< Back Harvesting Seeds for Native Prairie Restoration Marie Stolte, Master Gardener Dakota County Parks and Recreation is restoring the county’s native prairies. The goal is to grow the same types of plants that have successfully supported local insects, mammals, and birds for thousands of years. Prairie restoration rebuilds prairies by planting prairie seeds in areas that have changed to another land use. This article explains the how and why of native prairie restoration through the experience of Master Gardeners in Dakota County. Learn how you, too, can help wildlife and the environment by developing your own “pocket prairie” garden. Dakota County Parks and Recreation is attempting to restore the county’s native prairies. The goal is to grow the same types of plants that have successfully supported local insects, mammals, and birds for thousands of years. Prairie restoration rebuilds prairies by planting prairie seeds in areas that have changed to another land use. The science of prairie restoration has evolved over the last century as more is learned about how to do so effectively. Why should we be interested in prairie restoration? This excerpt from the Minnesota Department of Natural Resources explains why: [It] buffers and creates connections between isolated native prairie remnants, thereby making the larger prairie landscape more resilient to changing environmental conditions including climate change, pesticides, and invasive species [Helps to “sequester carbon,” (stabilizing carbon in the ground rather than in the atmosphere] Promotes water infiltration and storage (recharges groundwater, flood control, reduces erosion and nutrient runoff) Provides places for people to explore and learn about prairies Provides habitat for a variety of animals, from deer to damselflies Connects people—physically, intellectually, emotionally, and spiritually—with prairie's past, present, and future Minnesota Department of Natural Resources. In Dakota County, prairie restoration is done by collecting and using native seeds from its own “remnant prairies” (true native prairies) (or the seeds of those plants’ descendants) or buys native seeds from within 150 miles of Dakota County. “Restored native prairies” are prairies that have been restored with seeds from true native prairies or those plants’ descendants. Recently, Sam Talbot, a University of Minnesota Extension Educator, met with Dakota County Master Gardener Volunteers (DCMGVs) to collect native plant seeds from “restored prairies.” One group met at Lebanon Hills Regional Park and the other, at Whitetail Woods Regional Park. Note - seed collectors should always have permission before collecting seeds from any site. The purpose of this particular outing was to collect seed for various uses by the DCMGV. The seeds from these older restored prairies are not used as a source for new restorations so DCMGV was allowed to collect them. Some of the gathered seeds would be cleaned and packaged, then placed in the free Seed Library at Farmington Library for any county resident to grow . The rest of the seeds will be grown in individual DCMGV homes over the winter and sold at the group’s May Plant Sale. Proceeds from the sale support 30 of DCMGV’s programs, including children’s and community gardens throughout the county; raingardens created in conjunction with the City of Mendota Heights; and a new vegetable garden grown cooperatively with the County Juvenile Detention Facility in Hastings. In the fall, it is much more difficult to identify plants, especially after the flowers (and sometimes, the leaves) have faded and dried. And when many species of plants fill a prairie, it helps to know how high to look and what to look for. On this day, Sam had arrived earlier and cut stems to show the seed-bearing structures with leaves and seed heads. Each stem stood in its own bucket, along with an envelope with the species name. He answered questions about plant height and where they might be found in the vast prairie, then explained that no more than one third of the seeds on each plant should be gathered. The rest would feed wildlife over winter or fall and potentially reseed. Seed shapes and sizes differ wildly. Cup Plant’s seeds are roughly triangular and black with a brown ring around the edge; they are about an eighth of the size of a dime. Prairie Cinquefoil’s are tiny as sesame seeds and white, with multiple capsules per stem. Wild Bergamot’s almost invisible brown seeds sit loosely in hollow tubes that are packed together on a single seed head, just waiting for the wind to rustle and spread them. With a better understanding of what they were looking for, the DCMGVs headed out into the prairie. Each volunteer gathered one type of seed in a bucket, then took a different bucket to collect. At the end of the evening, buckets were emptied into the envelopes. Sam brought all of the seeds to Lebanon Hills to dry. In winter, he will host another DCMGV event to clean those seeds, removing chaff, leaving only the seeds for planting. “These events were such a great way to connect the Master Gardeners with the County’s natural resources,” Sam said, “and to explore our restored prairies through a completely different lens. I’m excited to continue our native plant conversations this winter as we discuss the next steps in the propagation process.” You also have a role to play in restoring native prairies and improving our environment. You can plant a "pocket prairie" in your yard. Even small prairie gardens can provide habitat for pollinators and other wildlife and give you the joy of a beautiful natural landscape. Each month, this publication has been and will continue to feature native plants that you can grow in your garden.

< Back Bleach Dying Dark T-Shirts Joy Johnson, Master Gardener We’re always looking for activities for our children or grandchildren in the summer. A fun summer project to do with children, or adults for that matter, is bleach dying. It’s cheap, fairly easy, fun and educational. In this article you will learn how to use plants from your garden to create a fun and pretty design through bleach dying. A fun summer project to do with children, or adults for that matter, is bleach dying. It’s cheap, fairly easy, fun and educational. I think in lists, so this is written as a list, it may seem long, but the actually process goes quite quickly. I just didn’t want to leave anything out, so you can have a successful product. 1. Wear really old clothes and shoes that you don’t care about (or go barefoot). 2. Warn anyone who has cuts or scrapes on their hands, as children often do, this will sting a bit, so prepare them for that. It does do a really good job of cleaning their hands! I would not wear gloves; you need to be able to grab and move wet delicate leaves and coins quickly and carefully. 3. Equipment needed: a. Two large buckets (5 gallon) b. Bleach c. Vinegar d. A medium sized spray bottle to put the bleach in. e. Lots of coins to use as weights. Rocks don’t work, I tried that. f. Water g. Kneeling pad if you’re doing this on the ground. h. A large place to work outside (I strongly suggest concrete). DO NOT work on the grass. The bleach will kill the grass. i. A dark colored t-shirt, one for each person, in their size. I chose black, but red, dark green and navy blue or brown work too. j. Cardboard or layers of newspaper to put inside the shirts so the bleach doesn’t soak through. Remember though, the shirt needs to lay flat. k. Extra-large weights for pressing down leaves that tend to curl. I used a piece of plywood and a wooden block. 4. Process: a. Half fill spray bottles with bleach. Rinse them off in case you dripped some on the outside. b. Fill one large bucket about 2/3 full with cold water. Add 2 cups of vinegar. This is your first rinse water. c. Fill the other bucket about 2/3 full with cold water. This is your second rinse water. d. Go snip or pick some leaves, ferns, flowers etc. Just remember that they need to lay flat. It’s helpful to choose leaves that have hair or fuzz on one side because they will stick to the shirt and you can gently press them flat with your hand. e. Put the cardboard inside the shirt. f. Lay the shirt flat on the concrete. g. Lay leaves and ferns on the shirt in whatever design you choose. h. Weigh them down with coins, being very careful to not let the coin go past the edge of the leaf. i. Use plywood or heavy blocks to press delicate curly or especially stubborn leaves that don’t want to lay flat. (Depending on what you have, it might take a while for them to relax and flatten out) this would be a good time to have a snack and work on identifying the various plants that were chosen. j. Remove any large weights carefully. k. Spritz shirt with bleach by standing above it and spraying straight down. DO NOT spray at an angle or you will get bleach under the edge of the leaves and your design won’t be crisp. l. DO NOT overuse the bleach. Wait about 5 seconds and the shirt should start to fade and show other colors. This part is quite fun, because you never know what colors are going to appear. m. Don’t wait too long. The bleach acts quickly and will eat holes in your shirt if you don’t get it in the vinegar water. n. Quickly and carefully remove the coins and leaves. DO NOT let them tip and drip bleach on your shirt. Remember they are covered with bleach. Any drips will show immediately. If you look carefully at the photos, I was moving too fast and dripped a couple of times when removing coins from the morning glory leaves. You can see that a couple of the leaves have drippy dots on them. o. Pick up the shirt by the shoulders and immediately immerse it into the vinegar water bucket. Swish it around, loosen it up, work the vinegar water all through it while counting to 60. p. Squeeze it gently over the bucket q. Immerse it in the plain water bucket and again swish it around and work the plain water all through it, this time count backwards from 60! r. Gently squeeze the shirt letting the water drain back into the bucket. s. Hang on the clothesline to dry t. Or you can wash all your shirts in your washing machine with a bit of detergent in cold water and tumble dry. Make sure no other clothes get washed with the shirts for this first wash. If you’re going to do this, have an empty, clean bucket or laundry basket by your work area to transport them to the machine. Otherwise, you’re going to have a trail of drips from outside all the way to your machine. u. Throw all your leaves and ferns in the trash. v. Rinse off all the coins in the plain water before returning them to your pocket! w. Throw cardboard away or recycle. x. Empty all of the spray bottles back into the large bleach container and thoroughly rinse them OR clearly label them “Bleach.” y. Empty the water buckets and return all other supplies.

< Back For Healthy Plants, Understand Your Soil First As you start to prepare your garden for spring planting, attending to the quality of your soil is one of the first things on the list. Testing and possibly amending your soil may not be as fun as planting, but these steps are crucial to the health of your plants. This article explains how to understand your soil and how to make it a beneficial host for your vegetables, shrubs, trees or flowers Mickey Scullard, Dakota County Master Gardener It all starts in the ground! Soil – or ‘dirt’ – is a critical component of gardening, along with water and sunlight. Soil is often the cause of plant problems and for this reason, it is important to understand what kind of soil you have. While this could become quite technical, there are some basic concepts that will help you understand what kind of soil you have and what actions you could take to improve it. As Dr. Anne Sawyer, from the University of Minnesota Department of Soil, Water, and Climate says, “healthy soils, healthy plants”. Dr. Sawyer explains that the soil is alive, full of microorganisms such as bacteria, fungi, and other organisms that support plant growth. In an ideal planting situation, the soil would be loamy. This means water moves through the dirt, it has a good mix of nutrients, and provide plants with the ability to grow their roots out with ease. Loamy soil looks black and crumbly and if you squeeze it gently, forms a ball or log. Clay soil is the least ideal type of medium for growing plants. If you squeeze it, it will form a solid ball. Clay soil does not allow water to filter through the soil particles, often creating puddles or little ponds. It is very compact. Plants struggle to grow their roots and often look stunted and unhealthy. Fruit and vegetables are unlikely to produce a good harvest. Sandy soil, like loamy soil, filters water but it filters water quite quickly, making it difficult to maintain a good moist soil. If you try to squeeze sandy soil, you will not be able to form any kind of structure. Plants grown in sandy soil require frequent watering and may sometimes look a little wilted. To further test your soil, you can do an infiltration test , which can be done with a soup can! This is a simple way to see how well water is draining and how long it takes your soil to absorb water. When possible, it is best to perform this test when the soil is dry so you can get a more accurate test. This infiltration test site provides step by step instructions. The good news is that you can amend most soils. That means you can improve your soil by adding organic matter. This can help to improve the soil’s water filtration (permeability) and aeration (air flow, oxygenation), which helps it to become similar to that ideal loamy soil. Soil amendments can also bring in nutrients that plants need to grow and thrive. For sandy soil , you would introduce materials that will give it more structure and help hold in the water or slow its movement. The amendments may include compost, peat moss, or decomposed/composted manure (never use ‘fresh’ manure – it can burn plants). For clay soil , you want to try to break up the solid mass. You would also thoroughly mix in compost and peat moss or other organic materials. However, to be frank, clay soil can be daunting to amend. Many people find they are not able to improve the soil sufficiently to create a better growing environment. Often the best solution for those with clay soil is installing raised beds and filling them with good garden soil. This article is not going to delve into several other important factors present in soils but you should know that plant problems may also be caused by several other soil-related factors. For example, knowing the ph of your soil (is it acidic or basic) can significantly impact plants. For this reason, it is usually recommended that you test your soil. Other articles in the Garden Buzz have talked about soil testing. You also can go right to the University of Minnesota website to learn more about soil testing and get instructions on how to take a soil sample and where to send it for testing. As you start to prepare your garden for spring planting, attending to the quality of your soil is one of the first things on the list. Not only will your plants be happier, so will you!

< Back Eating Winter Melon Looking for a comfort food that can come straight from your garden? Try this recipe using winter melon. Winter melon, also known as ash gourd, is a fruit native to parts of Southern Asia. The fruit grows on a vine and matures into a round or oblong melon that is approximately the same size and color as a watermelon. When it is ripe, it’s exterior turns a greenish-powdery ash-color. It tastes a bit like cucumber and is delicious in the soup described in this article. Anita Oakman, Dakota County Master Gardener Intern Winter melon, also known as ash gourd, is a fruit native to parts of Southern Asia. Winter melon grows on a vine and matures into a round or oblong melon that is approximately the same size and color as a watermelon. When it is ripe, it’s exterior turns a greenish-powdery ash-color. The fruit tastes somewhat like cucumber. It is said to have various health benefits and has been used in Asian medicine and cuisine for centuries. This recipe comes from an Asian-American vlogger named Yi who touts it as being a childhood comfort food for when you have a cold - a sort of “remedy for what ails ya”! Traditional Winter Melon Soup Ingredients: 1 lb winter melon, cut into 1” square pieces 1 lb ground pork Pork seasoning : 1 egg 1.5 tbsp cornstarch 1/4 tsp salt 1 large piece ginger, peeled and sliced 1 smaller piece peeled ginger for grinding or mincing Soup seasoning : 1 tsp olive oil 1 large piece ginger 1 tsp Sichuan peppercorn (optional) 1 tbsp Goji berries 2 tsp salt 1 tsp sesame oil Chopped green onion for garnish Directions: Crack egg into ground pork in medium sized bowl. Season pork with salt and one-half teaspoon cornstarch, mixing in ground or minced ginger until pork sticks together well. Pour olive oil into large saucepan on low heat, add sliced ginger and optional Sichuan peppercorns and heat until mixture becomes fragrant. Add enough boiling water to reach halfway up the sides of the saucepan. Form small meatballs from pork mixture and place into saucepan over increased heat, cooking until soup comes to a boil and meatballs are cooked well. Remove excess grease off top of soup. Carefully add chunks of winter melon to soup, cover saucepan, and let boil for 15 minutes. Stir in Goji berries, salt, and sesame oil. Serve garnished with chopped green onion.

< Back All About Peonies Tori Clark, Master Gardener Peony is a favorite flower of many northern gardens. The sweet-scented flowers are large and range in colors of pink, red, white and pale yellow with attractive stems of pink to red. Paeonia (pay-own-ee-uh) or peony is a favorite flower of many northern gardens. The sweet-scented flowers are large and range in colors of pink, red, white and pale yellow with attractive stems of pink to red. The foliage remains interesting in the garden all season. Peonies make an excellent border or small hedge but may need the support of a low wire cage to prevent flopping. They are low maintenance when established but need soil preparation and well-drained soil. Let the leaves fade before trimming to allow for the feeding of the roots that fix next years blooms. Peonies are native to China but are suited to northern United States. They need a winter chill and do not thrive in the American south where temperatures do not drop below 20 degrees F. Plant them correctly in full sun, a minimum of six hours a day, in rich soil. A layer of composted manure in the bottom of the hole will get the plant off to a good start. If planted to deep, flower buds will turn brown. Plant the eyes just below the soil surface 1 ½”-2”. The plant may not bloom the first year as it is still developing a root system. Bartzella Itoh Peony Peonies are not native to North America but have an interesting connection to Minnesota. For many years Faribault, Minnesota, was the peony capital of the world, due to the work of O.F. Brand family. O.F. Brand began planting peonies in 1868 from seed, sometimes waiting ten years for the plants to bloom. He sold bare root plants through a mail-order catalog. By 1920, Brand Peonies were the best in the country. The city of Faribault celebrated the fame with a community peony festival that featured a parade and peony queen. The depression ended the festival but Brand Peonies, later known as Tischler Peonies, continued until 1980. For many gardeners the easy maintenance, and fragrant cutting flower make peonies a favorite garden plant. Sources for this article Schier, Mary Lahr.

< Back Brussels Sprouts Brussels sprouts are one of the few crops usually harvested in late fall – late September through late October, depending on your location. Flavor improves with cooler fall weather and they can stay in the garden as long as temperatures remain above 20°F. Read more about how to grow and enjoy this late season vegetable. Julie Harris, Master Gardener As a ‘winter” plant, seeds can be planted indoors in June. They can be hardened off when the seedlings have 3 or 4 leaves (about 3 weeks). They can be planted outdoors about a week later. Direct seeded plants need twice the time to mature as seeds started indoors. You can also plant transplants. Brussels sprouts belong to the Brassica family. They are of the same species as broccoli, cabbage, collard greens, kale, and kohlrabi. Plant brussels sprouts in areas where they, or plants in the same family, have not been planted recently. Brussels sprouts require well-drained but moist soil with a pH between 6 and 7. Plant seeds 1/4 - 1/2 inch deep every 18 inches; thinning to 1 after they have germinated. Transplanted plants should be placed 18 inches apart. Brussels sprouts must have good soil moisture to mature properly. The amount of water needed will depend on your soil (clay, sandy or loamy) but keep the soil moist. Brussels sprouts plants are tender and you may need to protect them from wind and insects with a lightweight but secure row cover. Mulching is encouraged. Brussels sprouts look like mini cabbages and grow on the stalk of a tall, leafy plant. The sprouts develop where each leaf joins the stem, beginning at the bottom and moving up. Cut off the top 1 or 2 inches of the plant when the lowest sprouts are 1 inch in diameter. This will cause the sprouts at the top to grow also. Harvest brussels sprouts by removing the leaves and cutting the plant off at the ground. Keep the stalks in a cool cellar and harvest the sprouts over a few weeks. They are generally harvested from the stalk when the sprout is 2 inches or less. Sprouts will also keep in the refrigerator in a plastic bag for up to 2 weeks. Brussels sprouts are high in nutrients, fiber and vitamins and have a number of health benefits. They are especially rich in vitamin K, which is necessary for blood clotting and bone health. They are also high in vitamin C, which helps promote iron absorption and helps with tissue repair and immune function. What type of Brussel Sprouts should you look for? In recent University of Minnesota Extension Master Gardener vegetable trials, the top 3 rated varieties were: Gustus, Hestia, and Diablo. Brussels sprouts can be cooked in many ways but roasting is a common method. They can be frozen or pickled.

< Back Sunburned plants This article provides advice about how to recognize sunburned plants (sunscald), how to prevent it and what to do if your plants suffer from it. Marjory Blare, Master Gardener Many plants in your vegetable garden can get sunburned! For instance, vegetables and fruit can burn if the canopy of leaves over them is removed or if they are placed outside without being hardened off. House plants will suffer if moved from a shady room to a sunnier room. Sunscald is a synonym of sunburned. How to recognize sunburn/scald Look for: sunken bleached spots on fruits and vegetables; brown areas on pome fruits such as apples; or whitish, yellowish or browned foliage. Some things to do to prevent sunburn or sunscald 1) Harden-off plants before moving them to a sunnier location. Over the course of about 5-10 days, let them have longer and longer exposure to the sun (and wind). This goes for houseplants moving to a sunnier room or outside, as well as seedlings and plants grown in a greenhouse. 2) Plant out on an overcast day, if possible. 3) Water thoroughly before and after planting out. 4) In the case of house plants, research ideal light conditions and then observe the new location for several days in advance of moving them. 5) Water in the morning, and water at the root instead of the foliage. Water on leaves can magnify the sun to cause damage. 6) Be careful to not remove foliage shading immature fruit/vegetables when harvesting; this will let the sun reach areas that aren’t used to it. 7) Research whether your fruit/vegetable will continue ripening after picking and possibly pick them a little early, then promptly get them into the shade or a cooler place. 8) Try a different variety if you notice lots of sunscald this year. 9) Mulch freshly planted starts to conserve moisture, and facilitate root growth. 10) Do not fertilize right away; a high nitrogen fertilizer will direct energy into the leaves before the roots can settle in. 11) Kaolin- based products such as Surround® can reduce the chances of sunburn. Read the label for proper application rates and personal protective equipment. The label for Surround WP® includes language about reducing sunburn damage, but Surround CF® doesn’t. This product covers the surface of the fruit with clay. The clay will reflect the sunlight and reduce the sunlight that reaches the fruit. Kaolin should be applied to the point of near-drip coverage. Be careful to leave enough foliage free of the kaolin for photosynthesis. Check label for organic certification. Read more about the use of Kaolin from Purdue University here: https://vegcropshotline.org/article/sunburn-on-vegetables/ 12) Prune carefully to leave enough foliage to shade the fruit/vegetable. Prune diseased foliage promptly. 13) Water deeply. 14) Sheer curtains in the window can help house plants deal with too much light. 15) Use a shade cloth or bamboo screen to throw some shade during the hottest part of the day, and growing season. Shade cloth differs in the amount of shade that is thrown. A 70% cloth will let 30% of the light through. There is no one, right, answer to which percentage your garden needs. I used an orange snow fence last summer. Some things you can do after a plant shows sunburn/sunscald 1) Move plants (if possible) to a less exposed site. 2) Cut fertilizer rates to half strength until new leaf growth shows. 3) For tomatoes, try to keep temperatures below 95 degrees Fahrenheit. Tomatoes are native to alpine regions in Central and South America. The hottest days of Minnesota’s growing season can be hard on tomatoes. Try a shade cloth or bamboo screen to keep the tomatoes cooler during the hottest parts of the day. 4) Remove damaged fruit or leaves so that the plant can use its energy to grow more fruits, vegetables or leaves. 5) Be patient. Planning to prevent sunburn/scald before it can happen will lead to a happy productive garden!

< Back Fall Lawn Care Margie Blare, Master Gardener Fall is the best time to prepare for next year’s healthy lawn. Most lawns in Minnesota have cool weather grasses such as Kentucky bluegrass, tall and fine fescues and perennial ryegrass. Renovation Fall can be a great time to renovate your lawn. Seeding is easier because the seedlings won’t experience as much heat stress. Avoid adding additional nitrogen as it will over-stimulate the existing grass, thereby crowding out the new seedlings. Fine fescues will use less water, and tall fescues have longer roots. Figuring out why your lawn isn’t doing well before renovating it, will save you time and money. Go to: https://extension.umn.edu/lawn-care/renovating-lawn-quality-and-sustainability for more information. If you are laying down sod it, too, benefits from cooler temperatures in the fall and will require less water. Fertilization When temperatures are between 50 and 75 degrees your grass starts storing nutrients in its roots, to be used next spring, so late August through mid October is the optimal time to fertilize. Applying fertilizer in the spring leads to fast growth that suffers in the summer heat. Applying it after the ground is frozen creates run-off pollution and wastes your money. You should start with a soil test (go to: https://soiltest.cfans.umn.edu/ or e-mail soiltest@umn.edu ) before applying fertilizer. Weed Control Fall can also be a great time to kill those perennial broad-leaf weeds. They, too, are storing nutrients in their roots, so taking care of them in the fall eliminates them next spring. If using an herbicide (or fertilizer), always read ALL the instructions and follow recommendations for application rates, weather conditions and personal protection. Spot-treating may be the most economical and safest way to apply broad-leaf weed control products. Herbicide/fertilizer combination products can compromise both the fertilizer and the weed control effectiveness due to the ‘water-in’ vs. ‘leave-on-the-leaf” instructions. Crabgrass sprouts earlier in the year, so don’t use a crabgrass pre-emergent product in the fall. Go to: https://extension.umn.edu/planting-and-growing-guides/lawn-care-calendar for more information. Mowing Continue mowing until the grass stops growing, sometime in October. Make sure your mower blades are sharp and remove no more than the top 1/3 of grass length in any one mowing. During warm weather 3-4” long grass keeps the ground moister. But if you leave it long over the winter it becomes a vole paradise! Leaving (small) grass clippings on your lawn returns their nitrogen to the lawn and mulching blades help keep the clippings small. Bee Lawns Bee populations have been declining in part due to habitat loss and pesticide use. Having flowering plants in a lawn will help bees, and you also increase your lawn’s resilience; it will have healthier soil and need less watering, mowing, and fertilizer. White clover, Creeping thyme, Self heal, and Ground plum are low-growing flowers that tolerate mowing down to 3 inches. Turf areas that have little foot traffic or that are primarily aesthetic are great locations. Examples are: steep slopes, right of ways or easements. Do not use broad-leaf weed control on Bee Lawns: it will kill all the flowers that the bees need. Spot treat very carefully.

< Back What’s the Buzz about Bee Lawns? Marjory Blare, Master Gardener You may have heard about bee lawns on the news or from a friend or at a county park. And, you may be wondering what that is and why you might want to plant one in your yard. Read this article about bee lawns to help you decide if planting one is right for you. Did you know that about 1/3 of the plant-based foods that humans eat are insect pollinated? But pollinators are in trouble due to habitat loss, pesticides and parasites. Butterflies, wasps, flies, soldier beetles, and moths are also in jeopardy. A pollinator lawn provides the high-quality nutrition that pollinators need to survive. A bee lawn can attract over 50 species of bee! A bee lawn integrates low-growing flowering perennials with grasses. They require fewer pesticides, less fertilizer, water and mowing than a traditional lawn. Grasses in bee lawns can include grasses already present in your lawn, but, adding fine fescues and Buffalo grass will reduce the number of mowings needed per year and make the lawn more drought tolerant. “Strong creeping red fescue,” “slender creeping red fescue,” “chewings fescue,” “hard fescue” and “sheep fescue” can be grown with other cool-season grasses in full sun to shaded areas. Another alternative to cool-season grasses are sedges. However, they don’t take as well to mowing. Pennsylvania sedge grows to about 6”. White clover springs to mind when thinking of bees, but there are several other good candidates that will spread out the flowering season from spring through fall. “Self-Heal” (Prunella) and “creeping thyme” and “birds foot trefoil” are non-natives that should not be planted near a wild area, but can be used in urban areas. “Ground plum,” “sweet white violets” and “common blue violets” are native alternatives. Bee lawns can be treated similarly to lightly-used traditional lawns. They can be mowed (or not) at 3” or higher and take light foot traffic. Some examples of good places to plant bee lawns are: boulevards, steep slopes, primarily aesthetic areas, rights of way and easements. There are at least two ways to plant bee lawns. One is to start with bare soil (be aware that this area will have a “seed bank” of weeds.) and the other is to overseed. In certain cases, plugs might be a better choice.

< Back Our State Soil: Lester If you have ever planted anything in the ground, or even just dug a hole, you know how our soil can vary depending on where we live. As a gardener, it is likely you have had your soil tested and amended your soil to provide optimal growing conditions for your plants. Here in Minnesota, mother nature amended some soil on a very large scale and deposited about 400,000 acres of it across 17 counties, perfect for growing crops like corn, soybeans, and alfalfa, right in the heart of our state. Click here to get the dirt on Lester, our state soil. Lisa Olson, Master Gardener It’s 2012, and Lester, named after Lester Prairie, Minnesota where it was first acknowledged, is about to be named the state soil of Minnesota. Sen. Rod Skoe, DFL-Clearbrook, summed it up with, “Maybe with this [vote], we’ll stop treating our soil like dirt.” After all, it’s easy to take for granted what’s under our feet. But without soil, clean water and air, we literally can’t live. And by the way, to get right down to the nitty gritty, soil and dirt are not the same thing. Dirt is just that, dirt. It’s what you get on your hands or wipe off the floor. Soil, on the other hand, is a living ecosystem. Let’s dig in and learn what is so special about Lester soil and how it came to be designated as the “Official Minnesota State Soil” by Minnesota Governor Mark Dayton on April 28, 2012. It all began about 10,000 years ago when glaciers were sliding south across Minnesota, depositing rocks, pebbles, sand, and other materials along the way. After the ice melted, plants began to grow on the material left behind by the glaciers. The cycle had begun. Plants would grow, die, and become organic matter to nourish new plants that would grow, die, and support the next generation of plants. Forests and prairies eventually grew up and spread across the land. The roots from grasses and trees worked their way through the rocks and pebbles further breaking them down while water flowed into the soil dissolving minerals that had been deposited during the glacial period. The decaying leaves and grass from the forests and prairies added to the layers, called horizons, and continued to increase the fertility of this nutrient rich soil. In addition, the glacial moraines where the soil formed provided well-drained conditions adding to the ideal properties of the soil. In 1985, the Minnesota Association of Professional Soil Scientists put together a task force to select a soil to represent Minnesota. In 1987 they voted to recommend Lester as the state soil because they recognized the significance of this resource. It took a while for Lester to gain its status as the official state soil however. There is always competition with other groups, often schoolchildren, pushing for designations of various state symbols. But finally, after the blueberry muffin became a symbol and the black bear didn’t, and just in time for the Smithsonian exhibit “Dig It!” to arrive in Minnesota, with Lester featured as the state soil, and coinciding with the University of Minnesota celebrating its 100-year anniversary, and 40 years of the Minnesota Association of Professional Soil Scientists – phew! - Lester became official. From the Smithsonian State Soils exhibit Having a state soil provides unique opportunities for education about this precious resource, especially since agriculture is extremely important to the Minnesota economy. As we have learned, soil is one of the basic necessities to support life and we need to care for it. We can’t control drought, but we can control how we plant, protect our resources, and share our knowledge. typical landscape where Lester soil is found Resources for this article: https://www.startribune.com/hot-dish-politics-new-state-soil-is-a-standout/150303445/ https://www.soils4teachers.org/files/s4t/k12outreach/mn-state-soil-booklet.pdf https://files.dnr.state.mn.us/mcvmagazine/young_naturalists/young-naturalists-article/soil/soil-health.pdf https://www.soils.org/files/certifications/licensing/lester.pdf Photo Credit: Smithsonian Institute ( http://forces.si.edu/ ) (1), Minnesota Association of Professional Soil Scientists https://www.soils.org/files/certifications/licensing/lester.pdf (2), Smithsonian Institute ( https://forces.si.edu/SOILS/interactive/statesoils/html/State-Soils/Default.aspx?selection=Minnesota ) (3)

< Back Storing Root Vegetables Over the Winter Did you have a bumper crop of potatoes sweet potatoes, carrots, beets or turnips this year? You worked hard this year to produce that crop! Here are some helpful tips on how to store them to last for use all throughout winter and into spring. Joy Johnson, Master Gardener Potatoes Step 1: Dry them . After harvest, remove any damaged potatoes. Leave the rest outside to dry for a couple of hours. Don’t wash them but brush off excess dirt. Step 2: Cure them . Keep the potatoes in a dark, humid place for one to two weeks. These conditions help prevent rot. Indoors near the furnace works best. Spread out the potatoes in boxes and covered with cloth to enhance humidity. If you want to speed up this process, you can lay them out on racks or pallets, make a tent over them with light weight tarps or blankets and turn a box fan on under the tent. This will aid with drying them. Step 3: Choose a spot . For long-term cold storage, find a storage area that’s dry and dark, such as a basement, garage or shed with plenty of ventilation. A temperature of 35° to 40° is good. Step 4: Pack them . Pack the potatoes in a wooden crate, or something similar, with slatted sides and bottom. Alternate layers of newspaper and potatoes until the stack reaches 6 to 8 inches high. Make sure the newspaper covers the open slats so that light can’t get in. Step 5: Keep an eye on them . Check your potatoes monthly and remove any that are beginning to rot. One rotten spud will ruin the lot. Some varieties store better than others—russet potatoes are among the best. Sweet Potatoes and Yams Step 1: Time your harvest correctly . Wait for dry weather to dig up sweet potatoes and yams. Wet tubers attract insects, disease and mold. Wipe all the dirt off, but don’t get them wet. Step 2: Cure them . Lay the tubers in a warm location, similar to potato storage. Let them dry for 10 days to two weeks. Curing ensures excess moisture is drawn out, preventing mildew. Step 3: Pack them . Box up the tubers or wrap them in newspaper. Store them in a cool pantry or closet at 55° to 60°. If no cool place is available, pack them in layers of sand in barrels or crates. The sand cushions and keeps the tubers cool, but not cold enough to freeze. Place the containers in a moderately warm basement or garage. I have a barely heated garage. We keep it around 50 degrees or cooler, so that works well. Carrots, Beets, Turnips, Parsnips Step 1: Trim the tops . Cut off the leafy tops. Left on, they will draw moisture from the vegetable. Brush off loose dirt and remove any damaged ones. Step 2: Pack them . Place the root vegetables, unwashed, in boxes layered with slightly damp sand. I used Rubbermaid totes and buried the carrots, the tops that were exposed sprouted and grew very tall in the dark cool garage, but the carrots still tasted good. Step 3: Store them . Keep them in a cool place. Step 4: Keep an eye on them . Check regularly for spoilage and moisture, which causes rot, or dryness that could cause them to harden and split. Store your root vegetables correctly and you can enjoy your home-grown root vegetables all season! Photo credits: www.flickr.com (1,3), pxfuel.com (2)

< Back Creating a Butterfly Habitat Susan Ball, Dakota Master Gardener Would you like to attract a variety of butterflies to your garden? Different plants and environments attract different types of butterflies. So, if you really want to focus on particular butterflies, you can do it by planting appealing plants and creating welcoming environments. Read this informative article about what you need to do to attract butterflies to your garden. Would you like to attract a variety of butterflies to your garden? Different plants and environments attract different types of butterflies. So, if you really want to focus on particular butterflies, you can do it by planting appealing plants and creating welcoming environments. For example, asking, “what color flowers will attract butterflies?” is the wrong question to ask. Or rather, an incomplete question. Successful butterfly gardening requires creating “butterfly habitat,” which addresses each type of butterfly’s needs over its entire life cycle. The life cycle of the butterfly consists of four distinct stages: egg, larva (caterpillar), pupa (chrysalis: sack-like covering), and adult. A successful butterfly garden must provide food and habitat for both adult butterflies and their caterpillars all year round. Though many butterflies will drink nectar from a variety of flowering plants, their caterpillars are often limited as to which plants they can feed on. These plants are called “host plants”. I n order to create a successful butterfly habitat you must have: 1. A combination of adult nectar sources and larval host plants . Your goal is to attract the maximum variety of species to remain in your yard, reproduce and build populations, not to pass through for a snack on their way to more attractive living quarters. While butterflies need both host and nectar plants to complete their life cycles, an emphasis on host plants encourages butterflies to breed within given areas. Each kind of butterfly uses a limited range of host plants, but many host plants also provide nectar; in other words, a “twofer;” consider these plants first. Milkweed is a good example of a twofer: a host plant and nectar provider for Monarch butterflies. 2. Native species and their favorite landscapes . Most larval host plants are natives. Click here for a list of butterflies and their host plants from the University of Minnesota Extension. Remember that larval host plants are meant to be eaten . Damaged leaves or even plants that are completely defoliated is a good thing. It means your butterfly garden has attracted butterflies that have reproduced! And only a few plants are eaten to the ground by butterfly larvae; examples being, milkweed, parsley, dill, and fennel. These plants, however, often rebound several times before they must be replaced. On other hosts, like trees, most shrubs and grasses, feeding damage is barely noticeable, and what there is encourages healthy, new plant growth. NOTE: many nurseries use pesticides and these chemicals can be deadly to butterfly larvae. When buying host plants always ask if they have been treated with pesticides. Similarly, be very careful when using pesticides in your garden. If you must use chemicals, use them sparingly, and only treat the infected plant. 3. Shelter and a variety of feeding opportunities . Plants with different heights and growth habits appeal to a greater variety of butterflies by providing more opportunities for feeding and shelter. For example, when monarch and queen butterflies are looking for nectar, they are generally attracted to taller flowers. And don’t forget trees: wild cherry (which hosts tiger swallowtail ) and willow (which hosts Viceroy - a monarch look-alike) provides both food and shelter . In addition, wild cherry and willow also produce nectar that attracts many other kinds of butterflies. Tiger Swallowtail Butterfly 4. Plants which have different blooming times . These plants provide food for butterflies during periods of low natural availability. Flowers, like asters, which are late season bloomers, are important sources of nectar for butterflies (as well as bees and other pollinators) in the fall. Asters 5. Plants with different flower colors and different flower shapes . Different butterfly species are attracted to different flower colors : yellow, orange, white, and blue flowers as well as reds, pinks, and purples, but the shape of the flower is important too. The feeding behavior and length of the proboscis (aka: butterfly tongue) dictate which flowers butterflies visit. Long-tubed flowers are more accessible to species with long probosces whereas many composites (daisy-like flowers, like black-eyed Susans and Stokes’ aster) provide a feeding platform and easy nectar accessibility for smaller species. As a rule, small butterflies feed on nectar from small flowers and large butterflies feed on nectar from larger ones. Avoid double flowers. They are usually bred for showiness, not nectar production. 6. Plant in shade as well as full sun . Shade appeals to more butterfly species, especially forest species butterflies. The Giant Swallowtail and the Mustard White are Minnesota butterflies that prefer a shady woodland habitat. A rare shade-loving species, the Taiga Alpine , occurs in northern Minnesota exclusively, when in the lower 48 states. Mustard White Butterfly (first of its kind documented at Minnesota Landscape Arboretum, 2021 7. Group plantings of flowers . Group plantings of flowers are more apparent in the landscape, not only to us but to butterflies as well, allowing larvae to locate additional food in the event of shortage. 8. Habitat and food for “no-flower” butterflies . There are butterflies that rarely visit flowers, like the Question Mark . These butterflies hang around rotting fruit, animal dung, dead animal carcasses - which you may or may not want to supply - or tree sap. If you have fruit trees, you can leave fallen fruit, like apples, on the ground. Then there are also the “ puddle club ” butterflies - mostly male. They gather at mud puddles and stream banks to drink water and take in salts and other nutrients. You’ll attract these butterflies if you live on or near water, or you can create your own “puddles” to attract them. 9. Shelter for “overwintering” butterflies . There are about nine butterflies that overwinter in Minnesota, among them the Question Mark. Although many of them “hibernate”, only coming out during the winter if there is an exceptionally warm day, these butterflies need shelter during the winter months to survive our climate. Adjust your fall cleanup to provide habitat for them. Don’t mulch everything. Leaf litter from large plants, like hostas, for example, provides shelter for butterflies and other pollinators. Also, don’t cut your spent flowers and plants down to the ground. Leaving 18” to 20” worth of stems and leaves also provides shelter for these overwintering butterflies. In addition, you can take fallen sticks and stems, bundle them together and put them in an out-of-the-way place in your yard to provide more habitat. To sum up: Be less tidy! Provide a year-round combination of food and shelter for butterflies. Then, sit back this summer on your lounger, a glass of lemonade or ice tea by your side, and enjoy your successful butterfly garden!
