< Back Garden Myths Exposed Susan Ball, Dakota County Master Gardener Myths abound in the gardening world. The internet provides limitless information, but is it reliable? Or is it a myth that has floated around for so long it has become accepted as fact? To save your time, effort and money, make sure that the advice you read is research-based from a dependable source. In this article, we review several gardening practices and reveal which ones are based on science or myth. Myths abound in the gardening world. The internet provides limitless information, but is it reliable? Or is it a myth that has floated around for so long it has become accepted as fact? To save your time, effort and money, make sure that the advice you read is research-based from a dependable source. In the Garden Buzz, we support research-based information from reliable sources like the Minnesota and other state Extension Services, all of which are supported by the research universities in their state. Departments of Natural Resources, which also exist in every state, are another reliable source of science-based information. In this article, we review several gardening practices and reveal which ones are based on science or myth. MOTHBALLS KEEP RABBITS OUT OF THE GARDEN False - Through a process called sublimation, mothballs slowly convert from a solid into a gas that repels moths, not rabbits or other undesirable wildlife. Using mothballs in a way not specified by the label is also illegal and can harm people, pets, and the environment. PLACING GRAVEL OR POT SHARDS IN THE BOTTOM OF A PLANT CONTAINER WILL INCREASE DRAINAGE False - Rocks or shards in the bottom of pots can block or restrict water drainage because they reduce the size of the drainage hole. Water has difficulty moving from fine-grained soil (such as potting mix) to coarser material (such as gravel or pot shards). The water must saturate the fine-grained material before moving on. The best course is to fill the entire pot with high-quality planting mix. (University of CA Marin Co. Master Gardeners) LAWNS ARE LOW MAINTENCE False - Lawns are maintenance hogs. To keep your lawn looking good, you must water, mow, fertilize, edge, aerate, and weed. And that's just the beginning. You will also need to trap underground varmints, repair sprinkler heads, (assuming you have a sprinkler system - worse if you don’t - hauling out the hose and repositioning your sprinkler is time consuming and guaranteed to drench you) and seed or patch bare spots. That sound you hear? It's your shrubs laughing at all the time you spend babying that water-guzzling grass. Moral: plant more shrubs or replace your grass with ground cover. (University of CA Marin Co. Master Gardeners) CRACKING AN EGG UNDER YOUR TOMATO PLANT SUPPLIES NEEDED NUTRIENTS Maybe but not the best practice - Some people bury whole eggs or crushed eggshells in the soil when planting tomatoes to prevent blossom end rot. The theory is that the eggs provide extra calcium to the plants. While some gardeners swear by this method, scientific evidence does not support its effectiveness. While the calcium from eggshells will eventually leach into the soil, it may take some time to break down completely. Whole eggs buried in the soil could also attract pests like rodents or raccoons who may dig up your plants to access the eggs . Instead, focus on overall soil health. Healthy soil, rich in organic matter and beneficial microbes, will provide a much more consistent and reliable source of nutrients for your tomato plants. (University of Minnesota Extension; University of CA Marin Co. Master Gardeners) SOAP WILL KILL GARDEN PESTS True and false - Dish soap can kill small, soft-bodied insects like aphids and white flies but does nothing for insects with hard shells, like Japanese beetles. To be effective, the soapy water needs to not only to touch the insect but also coat the insect's body. This means turning over leaves to reach insects on the underside of leaves. (MN Extension Service; Colorado State University Extension) aphids on underside of leaves Mole crickets and caterpillars hide deep in turf and are difficult to detect. Drenching a small area of turf with soapy water can irritate the pests and cause them to temporarily surface where they can be identified, counted and treated. (Source: FL Extension Service) ADDING COFFEE GROUNDS TO YOUR SOIL HELPS ACIDIFY IT False - Fresh coffee grounds are acidic, but used coffee grounds are not. They're neutral. Therefore, adding your used coffee grounds won't change your soil pH. A better idea is to add used grounds to the compost pile. (University of CA Marin Co. Master Gardeners) WILTING LEAVES ALWAYS INDICATE THAT A PLANT NEEDS WATER False – There are other reasons that plant leaves wilt, so it’s worth exploring other causes before soaking your plant in water. In fact, wilting leaves could be due to waterlogged soil (which deprives roots of oxygen). Overly moist soil can also promote fungal disease. Certain bacteria may also cause leaf wilt. Another reason leaves wilt is animal damage to the roots. Gophers and nematodes feed on roots. Other animals may create tunnels under your plants that reduce root contract with the soil. Additional reasons for wilting leaves are over fertilizing or excess salt in the soil. (University of Minnesota Extension, University of CA Marin Co. Master Gardeners) GRASS CLIPPINGS LEFT ON THE LAWN CAUSE THATCH False - Thatch is a layer of grass stems and roots, living and dead organic matter that settles on the grass or ground. Excessive thatch, over a half-inch thick, creates an unfavorable growing environment for grass roots. They cause the lawn to grow very rapidly, inhibiting the decomposition of organic matter at ground level. Lawn clippings are often erroneously blamed for thatch buildup. Lawn clippings are very high in water content and rapidly break down. Overwatering and over-fertilizing have more to do with the buildup of thatch. (University of CA Marin Co. Master Gardeners) MEXICAN PETUNIA IS INVASIVE: DON’T PLANT IT! Maybe - It is true that native Mexican petunia is invasive and nearly impossible to get rid of once it invades. However, three non-invasive cultivars have been developed by the University of Florida and are sold as cultivars 'Mayan Purple’, 'Mayan White' and 'Mayan Pink’. And the sterile cultivar ‘Purple Showers’, taller and larger than its invasive relative, is available at big box stores. (Source: FL Extension Service) Note : All these cultivars are treated as annuals in Minnesota. In conclusion, when you come across advice that is not footnoted, or comes from a dubious source, it is always worth checking with your local extension service or a reliable research source. That will save you time, effort and money if the advice you have received turns out to be a myth. Click here for the University of Minnesota Extension website.

< Back Hydroponics at Home Have you heard of the hydroponic method of growing plants but thought is sounded too difficult to try at home? Hydroponics is a method of growing plants using a water-based nutrient solution rather than soil. Joanna Kapke, Master Gardener Hydroponics growing systems can seem daunting given what we may have seen or know about commercial and large-scale hydroponics; but at-home hydroponics systems can be quite simple and rewarding. When growing hydroponically, you have year-round growing potential, limited disease and insect pressure, no messy soil and even increased and quicker yields than when growing plants in soil. The most accessible hydroponics system for the at-home grower is called the “Deep Water Culture” method. This method consists of a container, water with nutrients and a support system for your plants. This method can utilize either a passive form of aeration (also sometimes referred to as the “Kratky method” due to research done on the concept at the University of Hawaii in the 1980s) or an active form of aeration involving a pump or other method of mechanical water circulation. More information about all forms and elements of deep water culture can be found on the U of M Extension website on their Small-scale hydroponics page. The basics elements for starting your own at-home hydroponics system are as follows: Container : The container you choose should be opaque, clean and made of food-safe ingredients. The size depends on the mature size of your plants or how many plants you will grow in one system. The lid will be important as it will hold the net pots the plants will grow in and keep them suspended above the water. Some ideas for containers include a 5 gallon bucket with appropriately-sized holes drilled in the lid or even a recycled pasta sauce jar (the lid is the perfect diameter to hold a standard net pot) covered in an opaque material such as thick felt or foam craft sheets. Container and growing medium: The most common type of container for your plant when using the Deep Water Culture method is a net pot. It is exactly what it sounds like: a plastic pot with holes that will hold the plant and growing medium, but also allow the root system to grow through it to reach the water and nutrients below in the container. There are many options for growing mediums in a hydroponic system, including rock wool, coconut coir, hydration, pumice or perlite. Whatever medium you choose, ensure it is clean by soaking it in water for 24 hours before transplanting your seedlings into it. Light : Most at-home indoor hydroponics systems will require supplemental lighting-especially in winter. Water : The first and most important element of your hydroponic water is its pH. Water should be tested for its pH levels both before and after adding nutrients. The ideal pH of hydroponic growing water is between 5.4 and 7. The second most important element of your hydroponic water is the maintenance of appropriate levels in your container. In a passive system there needs to be an air gap between the water and the beginning of the plants’ root system. The air gap is where the plants get oxygen. Generally, after the first filling—in which the water should just touch the bottom of the net pot—water should only cover up to half of the root system. Any more than this and the plants may die. Nutrients: Because only carbon, hydrogen and oxygen are available to plants in a hydroponic system, supplemental nutrients must be added to the water. Nutrient mixes specifically for hydroponic use are easy to find and come in many varieties. Plants to try and seed starting : The plants that do best in indoor hydroponic systems are lettuces, greens and herbs. When selecting seeds for your system, look for a hydroponics-friendly logo or signifier that many seed companies use. Seeds can be started in plugs of growing medium that will then be transplanted to the net pots when their roots peek out of the bottom. In addition to growing hydroponically indoors, hobby gardeners can grow many crops hydroponically outdoors in the summer. Other more advanced hydroponics options exist that can be adapted to home use as well. More information on outdoor hydroponics and advanced hydroponics systems such as nutrient film or drip systems can be found on the U of M Extension website on their Small-scale hydroponics page. This page has links to external and researched sources of information as well. If the supply resources and information available on the internet is overwhelming, there are several companies in the Twin Cities metro that can provide in-person guidance to get your own at-home hydroponics system started; for example: Ecogarden Supply ; St. Paul and Greener Gardens; Richfield.

< Back Stumped by a Stumpery? Deborah Snow, Master Gardener Have you thought about planting a Stumpery in your yard? A what? A Stumpery is basically a stylized shade garden. The garden uses stumps and logs as habitat for shade-loving plants; mainly, ferns, mosses and lichen. Colorful mushrooms may eventually grow and add color and character to the wood. When I tell people how excited I am about creating my own Stumpery, almost everyone asks, “What is that?!” As any gardener, I’m learning along the way. I tell them it’s basically a stylized shade garden. The garden uses stumps and logs as habitat for shade-loving plants; mainly, ferns, mosses and lichen. Colorful mushrooms may eventually grow and add color and character to the wood. So, how did this garden style get started? It came from a Victorian tradition of growing ferns among tree stumps. One of the first documented Stumperies was at Biddulph Grange in England. It was designed in 1856 by Edward William Cook, an artist and garden designer. Estate owner, James Bateman, was a wealthy horticulturalist who exemplified the Victorian passion for collecting plants from around the world. They created the Stumpery by stacking tree stumps into 10 foot high walls and filling the crevices with ferns and other plants. Due to the popularity of ferns during the Victorian era, the Stumpery was adopted as the garden space to display their collection. The Stumpery was emulated throughout England. One of the most famous Stumperies was created by Prince Charles of Wales, now King Charles, and is still a featured part of the gardens at Highgrove, his home in Gloucestershire. I did see a Stumpery in England but you don’t need to go that far. We recently toured a Stumpery at the Missouri Botanical Garden in St. Louis. I highly recommend a visit there if you’ve never been. What inspiration does a Victorian tradition from England have for American gardeners? A Stumpery is a workable concept for a modern garden. There is beauty in the architecture it provides. Its unique design lends itself to beneficial growing environments for shade-loving plants. Ferns are an obvious choice but any woodland plant could be included. It’s always evolving and that’s exciting to me! As the stumps and logs gradually decompose, the peeling bark provides habitat for insects that will feed the birds and frogs or pollinate the plants in the garden. Then come the mushrooms! I can’t wait for that. Next, I’ll talk about how to create your own Stumpery. It can be large or small. It can consist of several unearthed trees showing the roots or simply make use of logs or driftwood. You will use the arrangement of logs and stumps as an organizing feature. The wood will be equally important as the plants. Shade or part shade will work best and, if possible, plant on a slope for the best viewing. Along the edge of some woods would be perfect. My Stumpery is still very young. I put it together in the fall of 2021 and have added more wood and plants this last season. I’m sure it will get bigger as I learn more and find interesting pieces of wood. I’m always on the hunt. Friends have even contributed stumps. I will share the steps I used to get started. First, I chose and cleared the site. Next, I gathered some wood. I laid cardboard as the base to smother any weeds. I used logs as an outline and piled a mix of garden soil and compost inside. I created a mound since I didn’t have a slope. I partially buried some interesting stumps in and around the mound and covered it with wood chips for mulch. Now I was ready to plant. I’m such a plant collector and all that summer, before I started to build, I collected mostly ferns. I looked for varieties I didn’t already have wherever I went. Any time I saw something differed or unique I bought it. Also, I transplanted some ferns from my other gardens. So now I had a nice selection of plants to tuck in and around the wood. I planted ostrich ferns as a backdrop and started some mosses inside some hollowed out pieces of wood. I have continued putting in plants and stumps all this next season. And of course, me being me, I had to put a fairy garden piece in as well! I’m sure that will grow in the future. The garden looks mostly brown still but should be showing more green in the spring – I hope. I have struggled to keep it wet enough to get the mosses going. They don’t like this hot dry weather pattern we are stuck in. I’m hoping for a rainy spring and I’ll place more mosses. I’m researching best practices for moss and hope to do better next year. So, now you know what I know and I hope you are inspired to get out and build one of your own or at least find a stumpery to visit. There are lots of beautiful photos online to give you a better sense of what a mature Stumpery will look like. Good luck and happy gardening. Photo credits: Deborah Snow (all)

< Back Ornamental Grasses Carolyn Plank, Master Gardener Interest in Ornamental Grasses has exploded. They can fit into any garden theme. They provide height, movement, and long season color to your landscape. Most questions about ornamental grasses consist of when to plant them, trimming grasses and how and when to divide them. Little Fountain Interest in Ornamental Grasses has exploded. They can fit into any garden theme. They provide height, movement, and long season color to your landscape. Most questions about ornamental grasses consist of when to plant them, trimming, and how and when to divide them. Grasses are classified as cool season, warm season, or evergreen. Below is the difference between all the various types of grasses. COOL SEASON Most growth occurs in spring before temperatures exceed 75 degrees, and in the fall when temperatures cool down. You can cut back cool season grasses in the very early spring as soon as the snow is gone. WARM SEASON Most growth starts mid to late spring and flowers when it is hot. The grasses usually turn shades of brown from winter. The warm season grasses can be cut back in fall or mid to late spring. EVERGREEN GRASSES These ornamental grasses look like grasses but are not classified as grasses. Examples are sedge and carex. Evergreen grasses don’t ever go dormant. Do not divide these grasses as it will wound them and their ability to live through winter. Sedges DIVIDING ORNAMENTAL GRASSES You don’t necessarily have to divide grasses unless you want more plants, the plant has an obvious dead center, or they just haven’t done very well or have been declining in growth. CUTTING BACK ORNAMENTAL GRASSES Resist the urge to cut back younger grasses as it may result in winter injury. Trim plants to 1-2 feet if you want to maintain a tidy appearance but still hold leaves and snow for winter protection. There are so many ornamental grasses to choose from. You can click on the following link to find out some of the various types available. https://www.naturehills.com/grasses/ornamental-grasses . Here are some suggestions for shade tolerant grasses from the University of Minnesota Extension. For native grasses with great fall color , try these varieties: Little Bluestem, Big Bluestem, Switchgrass, River Oats, and Prairie Dropseed. Professor Mary Meyer, grass expert at the University of Minnesota recently named some of her favorite ornamental grasses : Hakone Grass, ‘Goldtau’ Tufted Hairgrass, Bowles Golden Sedge, Palm Sedge, ‘Blackhawks’ Big Bluestem. Blue Heaven Remember, not all ornamental grasses are perennials, some are only available as annuals. They all make a great addition to your garden and add a ton of picturesque scenes in the winter and all year long.

< Back Canada Anemone, A Hardy Native Groundcover James Lakin, M.D., Master Gardener Looking for a low maintenance, vigorous, hardy and attractive groundcover? Consider the native Canada Anemone. If you have a difficult slope that never grows grass, a clay or sandy patch that defies seeding with bluegrass or fescue, consider the Canada anemone. Anemone canadensis is otherwise known as meadow anemone, crowfoot or round leaf anemone. It’s a tough guy, found native throughout the Upper Midwest, most commonly on river banks, flood plains or low moist meadows. It provides an excellent groundcover in medium to moist soils. Although it will self-seed, it spreads primarily by rhizomes. This it does rapidly and will form good coverage in two growing seasons with proper conditions. As it is a vigorous grower, it can muscle out other low growing plants unless managed. If you need to contain this anemone, garden edging that goes 6 to 8 inches into the ground should do the trick. Once established, its attractive bright green foliage is graced with lovely white flowers in May, June and early July. The plant’s height usually is less than one foot and it can be mowed lower. It does well in full sun to partial shade. It seems that the cooler the environment, the more sun it will tolerate. Canada anemone settles in nicely in a variety of clay, sand or loam soils. It is hardy to Zone 3 through 6 to 7 although it prefers the cooler, more northern climes. Drier soils and hotter temperatures further south than central Illinois can be a problem. The plant’s name derives from Greek mythology. The nymph Anemone, like the plant, was quite a looker. She attracted the devoted attentions of the God of the West Wind, Zephyr. Unfortunately for all concerned, Zephyr was married to Chloris or in Roman nomenclature, Flora the goddess of flowers and springtime. Needless to say, Flora was miffed at Zephyr’s philandering. She terminated the relationship by turning Anemone into the eponymous flower. Ancient Greece being the strongly patriarchal society that it was, legend is silent as to how Zephyr fared. Like Zephyr, you would be well advised to exercise circumspection in your choices. In selecting ground covers most nurseries offer a variety of aggressive Asian or European imports, commonly Vinca minor or periwinkle. Vinca like so many other non-natives can escape cultivation and invade natural areas. Although Canada anemone is also a hardy grower it strikes a balance in the wild and coexists with other native species in a balanced ecology. Another significant benefit of planting a native such as Anemone canadensis rather than an import is Anemone’s contribution to pollinators. The flowers offer both abundant nectar and nutrient-rich pollen. Vinca , in contrast provides little attraction to native pollinators. For a low-maintenance, vigorous, hardy and attractive groundcover you could do well to consider the native Canada anemone. Photo credits: US Forest Service (1, 2)

< Back Dutchman’s Breeches (Dicentra cucullaria): Springtime Treat Jim Lakin MD, Master Gardener Read on for Master Gardener Jim Lakin’s exploration of this month’s featured Minnesota native perennial - Dutchan’s Breeches, a springtime treat! Antiquated articles of gentlemen’s attire do not make good names for flowers…usually. One exception is Dutchman’s Breeches, named after the ubiquitous knee-pants of the 17 th century Lowlands. This curious little ephemeral pops up each spring, looking for all the world like a series of Hollander’s pants hung out to dry. Dicentra cucullaria is native to temperate North America and can be found throughout the Midwest. It is hardy from USDA Zones 3 to 7. North Shore gardeners note! Dutchman’s Breeches is a forest dweller, preferring humus-rich, well-drained soil in part shade. You will usually find them on north or east facing forest slopes with underlying limestone. The foliage is fernlike, emerging in the early spring. Blooms last for about two weeks in April or early May, looking like upside-down white britches. The flowers are translucent, luminous white, standing out vividly against the primavera greens of the spring woodlands. Once the forest canopy closes and blocks most sunlight, the plant will stop blooming. Soon after flowering, the leaves will turn yellow and disappear. The flower stalks and leaves arise from an underground corm. Seeds are dispersed by ants, who are encouraged to carry the seeds underground as they are covered by a protein and fat-rich layer called an elaiosome. The elaiosome covering makes great food for the ant larvae. Once established, the plants grow to about 6 to 12 inches in height and width. They can be grown from seed although that is a bit of a process. Use fresh seed and sew in the early spring. The seeds need a warm period followed by a cold one before germination, so don’t expect sprouting until the following spring. An easier, and more expeditious means of propagation is to plant corms, which are similar to bulbs, in the fall. You should have a plant blooming late in the following spring. If you are interested in propagating more Dutchmen, the mother corm will produce offset corms after a couple of seasons, which can be separated and replanted in the fall. The landscape uses of D. cucullaria are numerous. It makes a classic addition to shade or woodland rock gardens. If you have a shaded slope, it will make a great spring accent. It nicely fills in a bare spot in a shaded raised bed. No matter where you plan Dutchman’s Breeches it will always produce a smile at the beginning of the gardening season.

< Back Pumpkins that will “Melt” Your Heart Julie Henrichs, Dakota County Master Gardener Intern An Amazing Pumpkin Creation for all ages! Are you looking for a fun way to make a unique and stunning looking pumpkin for Fall, but would prefer not to carve one? We have a simple decorative pumpkin idea that takes only a pumpkin of any size, shape or color (faux or real), a handful of broken crayons, a permanent marker, tacky glue, a hairdryer and don’t forget the optional googly eyes. Read on to learn how to make this adorable pumpkin craft for Fall that will “Melt” your heart. Supplies Needed for (1) Pumpkin Creation: Pumpkin - faux or real - any size, any shape - any color (colors really stand out on white pumpkins) 1 bottle of glue (tacky glue is best) Crayon pieces - paper peeled off Surface Coverings as crayons splatter when heated Googly Eyes (optional - size appropriate for pumpkin) Permanent Markers (optional - if choose to draw face on the pumpkin) Hairdryer (to be used under adult supervision) Let’s Get Set: Prepare work surface by covering with cardboard, tablecloth or similar covering because crayons splatter as they melt. Choose the crayon colors randomly or choose crayons to form a pattern of colors. Unwrap all crayon pieces that you plan to use. Kids usually enjoy unwrapping the crayons. On the top of the pumpkin (near stem) place several drops or light strips of glue and then place the crayons you have chosen on the glue. Crayons should be facing up and down. Let the crayons set in place before beginning the melting process. The more crayons used will result in more of the pumpkin being covered. Optional: Choose googly eyes and glue onto the pumpkin or use the permanent marker to draw a face on the pumpkin before melting the crayons. Let’s Get Melting: (adult supervision is required) Once the crayons are set in the glue, you are ready to begin the melting process. Make sure that the pumpkin is set on a sturdy and covered surface Have an adult prepare the hairdryer. Depending on the age of the child, additional adult supervision will be needed or the adult may need to run the hairdryer Turn on the hairdryer and point the hairdryer toward the crayons. The crayons will slowly melt and run down the side of the pumpkin. Caution: crayons may splatter while melting Please remember to only run your hairdryer for a short time to let it cool down and do not touch the hairdryer because it will be hot. Additional crayons can be added to provide various dimensions on the pumpkin. Make sure to let your Pumpkin creation cool. (If you set it in the sun or in a bright area place it on a plate or cloth to prevent damage to any surface.) Enjoy your creation through the Fall Season. If you used a faux pumpkin, then you can carefully pack away your creation for next Fall.

< Back Potentilla - A Hardy, Cold-Loving Workhorse Shrub Jim Lakin, MD, Dakota County Master Gardener Potentilla is a beautiful and useful native shrub. You may be familiar with the many cultivars of Potentilla that are on the market. But the native Potentilla has benefits that the cultivars do not. Read this article about the qualities of native Potentilla that may make it appealing for your garden. Dasiphora fruticose is known by a several common names: Potentilla , Shrubby or Bush Cinquefoil, Golden Hardhack, Shrubby Fivefinger, Widdy, Tundra Rose and Kuril Tea. Also, it is marketed as a number of attractive cultivars. The native, species plant is a quite hardy shrub doing nicely as far north as Zone 2. Thus, it is native to the cool temperate and subarctic regions of the northern hemisphere, often growing at high altitudes in mountains. It does wonderfully well and is long-lived in central Minnesota. Your author has had a fine patch with southern exposure which has done very well for over 30 years. Potentilla is a deciduous native perennial which grows to 3 to 4 feet being 4 to 5 feet wide. It is a member of the rose family, Rosaceae and produces a multitude of showy yellow flowers in summer into the early fall. It grows well in both clay and sandy soils. This could be a consideration for many parts of the Twin Cities. It will tolerate drought but does best in moist soils. In the wild it congregates in swampy, moisture-retentive soils. It will tolerate part shade, but does much better in full sun, especially if you want abundant flowering in summer. Potentilla is both deer and rabbit resistant. So, if you have “critter” problems, this would be a good choice for border, hedge or foundation planting. Potentilla will spread by rhizomes (underground runners) so it can invade adjacent beds. If it is acting as a woodland border plant, mowing will control spread. Potentilla as a flowering hedge The native is known to attract butterflies and is pollinator friendly. Data on pollinator attraction is scarce on the cultivars of Potentilla such as “Crème brulé”, “Marmalade” and “Happy Face”. There are over 130 named cultivars! As a general rule, they tend not to be as ecologically friendly as the native plant. You pay a price for a pretty face! Since Potentilla is hardy, disease resistant and low maintenance it is found in a wide variety of industrial and commercial plantings. If you are looking for such a ‘happy camper” for your landscape project, this would be a great choice. Photo credits: Walter Siegmund, Wikpedia (1), Oregon State University (2)

< Back Vegetables of Asian Origin That Thrive in Minnesota Community gardeners are increasingly interested in expanding their growing practices to include crops that originated in cultures other than their own. As Minnesotans, we have some options for growing vegetables that can be used in global cuisines and also promote sustainability. This article highlights three vegetables that originated in Asia, but with the right conditions and care, can also be grown in Minnesota. Logan Caola, Dakota County Master Gardener Intern The vegetables featured here originated in East Asia, a region that includes parts of Korea, China, and Japan. These vegetables have long been staple crops in traditional gardening environments and can adapt well to Minnesota's climate. With seasonal timing planned and soil conditions prepared in advance, we can grow these vegetables successfully. Growing them offers Minnesota gardeners an opportunity to honor global food heritage while diversifying our gardens and diets. Bok Choy (Brassica rapa subsp. chinensis) These leafy plants have been cultivated in China for thousands of years and are foundational to East Asian cuisines. Bok choy grows in an upright clump of dark green leaves, with very thick green or white stalks.1 They are versatile in the kitchen; commonly used in stir fries, soups and fermented preparations like kimchi. They can also be used as fillings for dishes such as egg rolls and dumplings. A great ingredient for homemade sauerkraut,2 Bok choy is packed with calcium and vitamins A and C, making it a nutrient-rich addition to the garden. Growing Considerations : As a cool-season vegetable, this plant is well-suited to Minnesota’s spring and fall growing seasons. Seeds can be started indoors or direct-sown in early spring. A second planting in late summer often performs better due to fewer pest issues but plant no later than late July. Soil & Care : They prefer fertile moist soil with a pH of 6.0 to 7.5. They can benefit from row covers that can protect against common pests. Harvesting : Bok choy matures in 30 to 45 days. You can harvest Bok Choy a few leaves at a time instead of waiting for the full head to develop. Bok Choy Japanese Cucumber (Cucumis sativus var. japonicus) This Japanese-originating cucumber is great for both pickling and eating fresh. While this is a warm weather crop, its growing conditions are not too dissimilar from common variety cucumbers! In Japan, these cucumbers are often thinly sliced and served with vinegar, sesame, or miso-based dressings. Planting Tips : Start seeds indoors in late April or sow directly outdoors in late May, after all danger of frost has passed.3, 4 Growing Conditions : Growing with a trellis is optimal as this provides support for vertical growth and encourages airflow. Make sure to water regularly to avoid bitter fruit! Harvest : Pick when 8 to 10 inches long for best flavor and texture. Frequent harvesting over the growing season will encourage continual production. Japanese Cucumber Shishito Pepper (Capsicum annuum) The shishito pepper is a wrinkly small pepper from Japan known for its subtle flavor. These peppers are commonly blistered in oil and sprinkled with sea salt, which brings out their sweet grassy flavor. Its ‘easy to cook’ nature and taste have made it a popular snack food throughout the U.S.! Gardening instructions for more familiar peppers can be followed for this variety as well!5 Starting Indoors : Like most peppers, shishito should be started indoors 8 to 10 weeks before the last frost and transplanted outdoors once night time temperatures stay consistently above 55°F.6 Soil & Sunlight : Requires full sun and well-draining soil. Make sure to utilize a balanced fertilizer (if necessary) to ensure continual fruit production during the growing season. Harvest Time : Pick when the peppers are about 3 to 4 inches long and still green. They can be harvested throughout the season. Shishito Pepper These Asian originating vegetables demonstrate that with just a little planning and care, we can grow our gardens to help expand our diets and try new things. Incorporating one or any of these options into your growing space not only broadens your culinary possibilities, but also introduces you to agricultural traditions that have been around for centuries, from all over the globe. While these crops are not indigenous to Minnesota, they perform well in our short growing seasons. Look for heirloom or traditional varieties from seed catalogs specializing in global crops, such as Kitazawa Seed Company , Baker Creek Heirloom Seeds , or Seed Savers Exchange . Remember: As gardeners, we don’t have to go very far to explore the world.

< Back Food for Thought in the Home Landscape Everyone wants a yard that is both beautiful and functional. For anyone wanting to grow food and make their landscapes more productive, there are many ways to incorporate both, outside of the usual raised beds, berry bushes, and fruit trees. Many more plants and plant parts than you might think are edible, and you can create layered designs to maximize density and diversity. Read this article for ideas and resources that you can put to use in your own yard. Greg Siems, Dakota County Master Gardener Intern When you think of an edible garden, what comes to mind? You might picture some raised beds filled with annual vegetables, a healthy patch of raspberries or rhubarb, or perhaps a small grove of dwarf fruit trees. Beyond these familiar and delicious friends, there are plenty of lesser-known roots, shoots, fruits and flowers that can be incorporated into your home landscape. The University of Minnesota Extension website provides a long of list fruits and flowers that can be grown in Minnesota and incorporated into your home landscape. Of course, only certain flowers are edible, so you must learn which flowers and which parts of a flower are edible. And make sure that the plants you eat have not been treated with harmful chemicals. Some examples of edible flowers listed by the U of M Extension at the above link are: nasturtiums, calendula, squash flower, borage, anise hyssop, bachelor buttons, beebalm and many more. Coneflower and Anise Hyssop If you are interested in exploring edibles and how they can be incorporated in your garden, visit the Minnesota Landscape Arboretum’s Foodscape . The Foodscape at the Farm at the Arb is a great model of “sustainable landscape design that combines the intentional use of food plants for their edible qualities as well as their ornamental value.” Thankfully, there doesn’t always have to be a tradeoff between a yard that looks good and one that tastes good. Foodscape at the UMN Landscape Arboretum Many of us are limited on space for our gardens. In relatively small urban and suburban lots, our eyes can easily become bigger than our yards when it comes to the wide variety of tasty things we could grow. If so, you should become familiar with the food forest approach. A food forest is made up of a variety of plants that mimic growth patterns found in nature. A food forest typically includes larger food-producing trees, small trees and shrubs, and a floor of annuals, perennial, root and ground cover crops and vines. Food forest projects are often group partnerships which make use of larger growing areas. However, you don’t need room for a full “forest” to take advantage of planting in layers. Making full use of the canopy, understory, and floor is a great way to maximize diversity and yields in your home garden. There are also culinary and medicinal uses for many plants that were not intentionally cultivated. Dandelions are a well-known example; others such as plantain , purslane , and even the dreaded creeping bellflower provide some benefits. Learn more about what to look for at this U of M Extension article on weeds so that the next time you are out weeding, consider if there might be a few things you’d like to try in your next salad! What’s more, if you happen to have a taste for these plants, you can harvest to your heart’s content, knowing that you’re helping to strengthen your local ecosystem in the process. Inspiration abounds for expanding your palate and introducing some exciting new elements to your existing panoply of plants. Check out a few of these other Extension resources for more ideas and information: “Edible Gardens for People and Pollinators” - University of Minnesota Extension “The Incredible Edible Landscape” - Iowa State University Extension “Edible Perennials” - University of Illinois Extension “Foraging for Backyard Edibles” - North Carolina State Extension So, take advantage of this great research and put it to use in creating an attractive and edible garden in your yard.

< Back How to Care for Blueberry Bushes This Spring Do you love to eat blueberries? No blueberries are better than the ones you grow in your yard. If you are growing blueberry bushes in your yard or want to do so, read this article for some tips on what you can do this spring to help your blueberry bushes flourish. Joy Johnson, Dakota County Master Gardener I love to eat blueberries and also wanted to add some bushes to my yard for pollinators and privacy and beauty. So, adding a few blueberry bushes seemed to be a good option. We planted 5 blueberry bushes a couple of years ago and have moved them around the yard a couple of times, trying to find a location where they would thrive. In the process, I’ve learned several things that you can do for your blueberries in early spring before they’ve even budded that will help them thrive. Blueberries have very shallow roots, so remove all weeds and grasses that may have grown up around the bushes, then add a layer of mulch 3-4 inches thick. After that, look carefully at your bushes and prune out any dead or dying branches. Also prune out any conflicting growth; branches that are growing into the center or crossing over or rubbing against other branches. Another thing to do is to step back and look at the overall shape of your bush and prune so it has a balanced look on all sides. For smaller branches, use a bypass pruning shears or snips. For larger more mature bushes and branches, use a pruning saw. You should do this pruning while the bush is fully dormant, and no buds have formed. Blueberries need an acidic soil with a pH between 4.5 -5.5. There are a couple of ways to amend the soil around your blueberry bushes. You can use elemental sulfur pellets available at Walmart, Fleet Farm, Ace Hardware and on Amazon. Wear gloves when you apply. Wait to apply until the soil temperature is at least 55 degrees. Sprinkle 2 handfuls in a ring around the plant, on top of the mulch and then lightly rub it into the mulch. You can also use a fertilizer that has a 5-3-3 balance or get a fertilizer like Plant Tone or Holly Tone. These are usually promoted as evergreen and azalea food (those plants also like a more acidic soil). Only fertilize once this year. Then you should add a layer of compost 2-3 inches thick in a 2-foot diameter ring around your bushes. Make sure your compost smells like grass, not garbage, to ensure that it is fully composted. Next add 3 inches of a natural mulch, not dyed. For example, bark mulch, woodchips, cedar or hay, or pine straw. Mini pine bark nuggets are mildly acidic and can help acidify your soil. Make an 18–24-inch ring around your bushes, 2-3inches deep. The last step is to wet down the entire area. Keep in mind that doing all these things, like adding compost and mulch, won’t last all year. Check your bushes throughout the growing season watching for decomposition, bare soil, and/or weeds starting to creep in. Pull the weeds, reapply a 2–3-inch layer of mulch as needed. Then look forward to a delicious blueberry harvest. Photo Credits: University of Minnesota Extension (1), Joy Johnson (2-6)

< Back Practical Pointers for Planning Your Garden The seed catalogs are here so spring must be around the corner! It’s time to turn the dreams of January into the plans for a new or renewed garden in your yard. Read this article to gain some practical pointers for planning your garden. Let’s get planning! Joy Johnson, Master Gardener It’s only February but you probably have already received some seed catalogs in the mail reminding us that spring will soon reappear. As we look longingly out our windows, it’s a great time to start thinking about a new or improved garden for your yard. A new garden can replace an existing garden, enlarge or re-shape an existing garden or carve out a completely new space in a neglected part of your property. When designing a new garden, there are some general design principles and other things you should consider. I am old school and prefer to do my thinking with a pencil and a large sheet of paper. It’s a good idea to sketch out the area you have in mind. Ask yourself some basic questions as you sketch. Topography Is the new garden area on a slope? If it is, will you need a retaining wall or terracing? For example, we designed a new garden along the east side of our yard. It has a gentle downhill slope. We wanted to add some contour to our flat front yard and create a visual barrier to block the view of the side of our neighbor’s house. We needed a retaining wall to add height and keep the garden on our side of the land. The wall ended up being 30 feet long and 4 feet wide on each end. It is 4 feet high and made from bricks and large boulders. We filled it with soil and made a small hill, with two depressions and an S shaped curve along the front side for visual variety. Light How much daylight does the area receive? Watch the area over several months and make note of any areas shaded by buildings or trees for more than 6 hours a day. An area that is in the shade for at least 6 hours a day will only support plants designed to grow in the shade. Sun loving plants need a minimum of 6 hours of full sunlight. If you are just starting this process in February, you will need to remember back to June, July, and August to determine the amount of sunlight your spot will receive during the summer. This can be very different than in the winter months due to the angle of the sun and day length. Specimen Plants Do you have any specimen plants in the area that you want to highlight (or plant new in the area)? How can you set it, or them, off? Some ideas are to highlight a specimen bush or tree with a contrasting color of mulch or a contrasting low growing ground cover. We wanted to highlight a weeping pussy willow, which has an interesting shape, but is basically green the entire growing season, so we planted purple Bugleweed around the base. The Bugleweed has tiny purple flower spikes during June, July and into August, so it looks like the Weeping Pussywillow is floating on a purple carpet. Color Palette What’s your color palette? When designing a garden that includes blooming flowers and shrubs, it’s pleasing to the eye to group similar colors together and to plant numerous plants of the same variety. This is called color block gardening and is effective if you have a large area to fill. For example, since our area is long and narrow, we planted one section with weigela which has burgundy leaves and pink flowers for most of the summer. Around one side of the weigela we planted Asian Lilies in a variety of pink hues. Beneath them and trailing down the small hill we planted a low growing creeping sedum which gets tiny pink flowers. This leads us to another design element you should consider. Plant Size Plant size. It is pleasing to the eye to have a variety of heights in your garden. You should use the Rule of Thirds. The plants at the back of your garden should be two-thirds taller than the plants in front of them. In the example given in number 4 above, the Weigela are taller than the Asian Lilies and they are both taller than the sedum. They are in the same color palette as the peonies. The creeping juniper softens the edge of the rock boarder and anchors the color palette with a dark green. A variegated willow with its very pale pink spring leaves is a light back drop at the edge of the garden. Much taller Smokebushes with their burgundy, green leaves are two-thirds taller than the Weigela. Another example from our garden is the row of Arborvitae along the back of the garden that will eventually grow taller than the Ninebark, Forsythia and Weigela that are planted in front of them. In front of those bushes, we have planted a variety of shorter flowers, grasses, and creeping ground covers. Soil Type It is important to look at your soil type. That will be hard to do in February, but when spring comes, it’s a good idea to send in a sample of the soil from your garden area to the University of Minnesota . They will send you back a soil test report that will let you know if you need to add any phosphorus or Potassium to your area. If you google “soil testing University of Minnesota” you will find directions for submitting a sample. Make a Sketch As we looked through all our gardening catalogs and downloaded plant information from various websites, it was easier to visualize our ideas if we cut out the physical pictures of the shrubs and flowers we were considering and taped them on to our paper lay out. We used a 1” = 1’ scale, to get an idea of the size. After taping the pictures on our layout, we sketched a circle around the plant to show the size of the full-grown plant. Be Flexible Flexibility is the last element of design. A flat piece of paper and photos do a good job of preparing you for the final garden look, but the contour of the land will also affect how things look. We ended up redesigning a couple of areas and moving plants around in the spring when planting began to get the look we were going for. Also keep in mind that the mature size of a plant is very different than the seedling you first get from the nursery. Your garden may not look as full as you want it to until the plants have had a couple of years to grow and settle in. Sensory Considerations A couple of other considerations: plant plants with a pleasing fragrance near your front door or other heavily trafficked area, so people can enjoy them. Don’t plant ‘unwelcoming’ plants near your front or side doors. Things with thorns, spikes, trailing branches, or pungent smells are better suited to other areas. Some tall grasses make lovely swishing sounds when the wind blows through them, consider using those near an outdoor seating area or near an entry way for auditory variety. There are many things to consider when planning a garden so enjoy the process. Choose one or two main goals or focus points (is this an edible garden or a cutting garden, or a garden to block an ugly view or a “native-plants-only” garden). Don’t let yourself get pulled off track by all the beautiful plants you see in the catalogs, online and at nurseries. Keep a narrow focus for the first year. You can always add more plants and move plants in the following years. That’s one of the fun things about gardening, plants are always changing and growing. Photo Credit: Joy Johnson
