    < Back Jack Pine (Pinus banksiana) Jim Lakin, MD, Dakota County Master Gardener Not every evergreen looks like it’s out of a Rudolph’s Christmas special. Jack Pine is one of them. But this native pine tree has many other virtues to consider if you are looking to add evergreens to your landscape. It is adaptable to good and poor soils, sun or shade and an attractive host to wildlife. Read this article to learn more about this interesting evergreen. Not every evergreen looks like it’s out of a Rudolph’s Christmas special. Jack Pine is one of them. It tends to be short and bushy, especially in poor soils; not the classic Holiday Tree. Yet in spite of that, it has many virtues for the landscaper. Its bushiness makes it an excellent windbreak or privacy screen, especially if you are planting it in difficult soils or part shade. In rich soil, however it can achieve 30 to 50 feet in height, spreading 20 to 30 feet in width. Jack Pine provides an excellent habitat for wildlife, producing abundant cones and providing good cover in winter. If you are naturalizing a large plot, this tree is a good choice. Jack Pine grows across the northern forests of North America, penetrating to Central Minnesota, although some strains will do well even further south. Indeed, the tree will grow from zone 2 through 6. It is, however, sensitive to pine wilt in these more southern locations. Virginia Pine, a close relative, is a better choice in the Southern Midwest. Since Jack Pine does grow well in poor soils, it is often a pioneer plant in burned off or disturbed areas. If you have access to a pure Jack Pine forest, blueberries frequently proliferate in the understory. Making for great foraging! Jack Pine is easy to grow from seed, although sometimes the cones have to be burned to force seed release. The tree requires full sun although it will thrive in relatively poor soils. With two short needles per bundle, it produces a lovely fine texture. In the winter, needles tend to turn a golden green, forming a nice contrast to the true green needles of other evergreens. In environments with cold winters, Jack Pine is relatively maintenance free. Further south, as noted, some difficulties can occur. Root rot and certain rusts are potential problems. So, for you folks Up North, this one’s for you! Photo Credits: Missouri Botanical Garden (1-2)

    < Back Pizza Anyone? Pizza Anyone? Why does my pizza taste so good? Home grown herbs – fresh pizza seasonings! Don’t forget to grow those incredible herbs with your children or grandchildren in a fun way that can be used not only this summer (if you are already growing herbs), but throughout the year. Read on to learn how to grow, harvest and preserve basil, parsley and oregano. Julie Henrichs, Dakota County Master Gardener Intern Why does my pizza taste so good? Home grown herbs – fresh pizza seasonings! Don’t forget to grow those incredible herbs with your children or grandchildren in a fun way that can be used not only this summer, but throughout the year. Introducing how to create the containers and then grow, harvest and preserve basil, parsley and oregano. Pizza is one of the favorite foods of children and adults alike. What can be better than to help your children or grandchildren grow their own seasonings for their pizza? Basil, parsley and oregano can be started inside or outside and can be directly sown or grown from seed or a plant starter from a store. Supplies Needed: (3) terra cotta pots/saucers (4” or smaller) Small bag of potting soil Oregano, Basil, Parsley Seeds or Plants Plant Markers (purchased or create from craft sticks) Optional: acrylic paint, brushes Preparing the containers for planting: Choose three 4” clay terra cotta pots and saucers. Find colorful acrylic paints, small paint brushes and a cup of water for rinsing brushes. Painting the clay pots is optional, but it is a fun activity for kids/adults to be creative and decorate each herb container - it also adds a pop of color. The herb names (Basil, Oregano and Parsley) can also be painted onto the terra cotta pots. (Purchased labels can be used or simple labels can be created with craft sticks as well.) Paint or Decorate containers & labels as desired - let dry before planting (for the younger painters - use an old large t-shirt as a paint smock and cover surfaces) How to turn herb seeds/plant starters into pizza seasonings? Fill (3) terra cotta pots with potting soil - moisten with water and you are ready to plant Plant herb seeds (each herb in one container separately) as directed on package OR Plant herb starter plants into the terra cotta pots. Make a hole or opening in the soil and place the starter into the opening. Press soil around the starter plant. Mist the soil or water as needed (terra cotta pots can dry out quickly so monitor the moisture needed). Place containers in a sunny location outside or place in a bright window sill or under grow lights. 6 to 8 hours of sunlight is needed per day (8-12 hours if growing inside under a grow light) Monitor daily - keep seeds moist, but not too wet and monitor for germination Be patient and watch for signs of growth Once herbs are growing they may be pinched back so that they do not become leggy - harvesting can also help in keeping the plant happy and healthy Continue to harvest the herbs and use fresh on pizza - “Home Grown Herbs” - Yummy! (Herbs can also be dried and/or frozen (ex. - basil can be turned into a pesto and frozen) and can be used throughout the year.)

    < Back Holiday Trees Tori Clark, Master Gardener Tis the season. If your holiday decorating includes a fresh cut tree, here are some things to consider before selecting your tree and some tips to ensure it lasts throughout the season. If your holiday decorating includes a fresh cut tree, there are some things to consider before selecting your tree and tips to ensure it lasts throughout the season. Most of the trees you will find at cut-your-own or pre-cut lots will be one of these four types: Fraser fir trees have bright green, flattened needles; ½ to 1 inch long. They have some of the best needle retention and a pleasant scent. Fraser firs have strong branches which angle upward making them a great choice for heavier ornaments. Fraser fir Balsam fir needles tend to be a little longer, about ¾" to 1 ½" . The long-lasting needles are flat and rounded at the tip. These firs have a dark green color and are very fragrant. Balsam fir Scotch pine has very stiff, dark green needles about one inch long. The needles will stay on the tree even when dry. Scotch pine White pines have soft, blue-green needles, 2 to 4 inches long, that will stay on throughout the holiday season. The trees have a full appearance and are best suited to smaller ornaments. White pines have little or no fragrance, but can have less allergic reactions compared to more fragrant trees. White pine Whether you are shopping at a pre-cut tree lot in town or cutting your own, make sure you have a good idea of the height and width the desired spot in your home can accommodate. Also check your tree for freshness. Trees are often cut weeks earlier, so make sure the needles are green and flexible and do not fall off when you run your hand over a branch. If you are not putting your tree up when you bring it home, keep it in a shaded unheated location. A fresh cut to the trunk of your holiday tree will help it last through all of your holiday celebrations so remove 1-2” of the trunk then place the tree in a stand with water. A good quality tree stand will hold one to two gallons of water. Keep it filled with water for a long-lasting tree that is fragrant and doesn’t drop too many needles. Be sure to keep your tree away from heat sources like vents and fireplaces to reduce drying. Look for resources in your community for recycling your tree after the holidays.

    < Back Planning to Promote Success in Your 2022 Vegetable Garden March is a great time to start to plan for your summer vegetable garden. Whether you’re planning your first vegetable garden or you’re an experienced vegetable gardener, there are things you can be doing to enhance the probability of a successful growing season. Linda Stein, Master Gardener Experienced gardeners review last year’s successes and failures. Some problems that you encountered may be indicative of issues that you may wish to address as you prepare for the upcoming growing season. If your vegetable plants had lush leaf growth but limited vegetables, it may be because your soil has excess nitrogen and/or inadequate phosphorus. When we experience a thaw and you can dig in your garden, you may wish to have a soil test to determine how to amend the soil to promote effective growth. Go to the University of Minnesota’s website ( https://soiltest.cfans.umn.edu/testing-services/lawn-garden ) for details on how to submit a sample for testing. If you have been planting the same vegetables in the same locations you may have seen poorer harvests. As you prepare for the coming year consider rotating the location of specific plants to reduce damage from insect pests, limit the development of vegetable-specific diseases and manage soil fertility. Vegetables should be considered in the following groups: root vegetables, fruit-bearing vegetables, legumes, and leafy vegetables as you rotate the location of plants. So, for example, don’t plant fruit-bearing plants such as bell peppers where tomatoes were planted last year. Instead, plant legumes, root vegetables like carrots, or leafy vegetables such as lettuce. Many vegetables can be started from seeds, planted indoors and transplanted outdoors when the weather warms. March is the appropriate time to plant broccoli, brussels sprouts, cabbage, and cauliflower seeds indoors so they are ready for the Minnesota growing season. If you are planning your first vegetable garden, consider the following: Review your yard to find a location that receives at least 6 hours of sun. Decide which vegetables you would like to grow. Some of the easiest ones to grow include lettuce, cucumbers, green beans, summer squash, root vegetables (such as radishes and carrots), bell peppers, tomatoes, and peas. Review online listings or plant catalogs to determine the specific variety of the vegetables to plant. Make sure the plant will survive in Minnesota’s climate. Also consider the production habit of the plant. Some varieties continue producing over a prolonged period of time while others produce all their fruit over a short period of time. Develop a layout for planting. Consider traditional straight rows or square foot layouts. Consider how many plants of each vegetable to plant. Some vegetables like to be planted close together while others prefer space to allow good air flow around the plant. Plant tall plants along the northern end of our garden so they don’t shade shorter plants. Send a soil sample to the University of Minnesota to determine how you should amend the soil to promote plant health and vegetable production. (See link to the soil testing site above.) Consider March the start of your vegetable growing season and prepare for success in your 2022 garden.

    < Back China Bayles Series By Susan Wittig Albert In the mood for a little light reading while exploring the world of herbs? Master Gardener and herb expert Shari Mayer reviews the “China Bayles” mystery series by Susan Wittig Albert. Each of the multiple volume mystery series centers around a particular herb. Read this article to learn more about this clever and informative mystery series. Reviewed By Shari Mayer, Master Gardener In the mood for a little light reading with an educational bent? Check out the China Bayles series by Susan Wittig Albert. This series can be likened to ‘The Cat Who…’ mystery novels, by Lilian Jackson Braun. Even if you’re not a mystery buff, these books are delightful and you learn a lot about herbs along the way. It’s a lovely read for a road trip, up at the cabin, or just sitting on your porch after a long day gardening. This series is comprised of 28 mysteries to date, each centering around a particular herb. It’s a great way to explore the world of herbs. I would recommend reading in order, although it’s not required. Albert has been publishing this series since 1992, garnering several awards along the way, including the Agatha award. She has a Ph.D. in English from Berkeley, and has also published under pen names, including Carolyn Keene and Robin Paige. In this series China Bayles is a high-powered attorney, who left that world behind to open an herb shop in a small Texas town. Each book is centered around a particular herb, and it’s amazing how much you learn about that herb as the plot thickens. I’ve been recommending this series for years now, and it doesn’t matter your age or inclination, everyone seems to love them. If you haven’t tried them, now’s the time. I used to get them from the library, but I hear Kindle, as well as Amazon Prime, both have options. Happy reading!

    < Back Yes, You Can Grow Shade-Loving Plants Marjory Blare, MD, Master Gardener Many people think that shade just creates problems for the garden. This article explains how wrong that can be. Read on to learn more about which trees, shrubs and perennials can prosper in your shady garden. You may consider your garden to be “shady,” but is it in full shade or part shade? Full shade is defined as an area that receives less than 4 hours of direct sun per day. Part shade is defined as a garden that receives 4 to 6 hours per day. How much sun (take into account reflected or filtered sun) does your garden get? The easiest way to measure sunlight exposure is to simply observe your planting area every 30 minutes or so throughout the daylight hours over a week or two. Use those observations to determine the average amount of time the area receives sunlight, dappled sunlight, or shade. When you have determined the average amount of sunlight an area receives, you can choose plants that match the conditions of the site. Research the plants before buying and planting. You should also take into account the condition of your soil. Is it clay, sandy or loamy, is it dry or wet, acidic or alkaline? (Click here to find out about soil tests: https://soiltest.cfans.umn.edu/ ) Consider the following plants for your shady garden. SMALL TREES Saucer Magnolias Saucer Magnolias (30’) are shrub-like trees. They grow at a moderate pace producing goblet-shaped flowers in shades of white, pink, and purple. The buds are attractive to deer and rabbits. They grow well in many soil types, especially organic-rich soils that stay moist. They are useful in tight spaces and can be near a foundation without causing problems. Eastern Redbud (zones 4-9) Eastern Redbuds (20’-30’ x 25’-35’) produce violet-pink blossoms on bare branches in early to mid-spring before heart-shaped foliage emerges. Eastern Redbuds grow at a medium rate, and tolerate many soil types, from clay to sand, from alkaline to acidic. Water regularly when young; once established, they’re drought-resistant. SHRUBS Azalea The University of Minnesota’s Northerns Lights series has a wide range of colors. https://mnhardy.umn.edu/azaleas . If you look at other growers, be sure to purchase plants grown in Minnesota. Acidic soil (pH 4.5-6.0) is very important. Try to site azaleas at the edges of shade. Aronia, Chokeberry Aronia does best in part shade. In the spring they are covered in white blossoms, in the fall they provide bright color. Chokeberry Aronia Snowberry Snowberry produces tiny pink flowers and white berries the size of peas. Is is very hardy with a wide tolerance of soil types, and moisture conditions. The drupes attract many birds. Weigela Weigelas, like azaleas, bloom better with more sun rather than less, but are not so picky about pH. The blossoms are white, pink, mauve and red. The leaves can range from light green to dark and many have stunning bronze foliage. Weigela PERENNIALS If you would like more ideas, please download this table. It should dispel any question in your mind that there are a wide variety of perennials that will grow well in your shady garden.

    < Back Hello Spring! Julie Harris, Dakota County Master Gardener April is the month when we can finally spend time out of doors, breathing fresh, cool air and watching plants and trees “green up.” April is also the month to get your garden in gear for the season. But do so slowly. Starting too early can compact the soil and disturb pollinators that may still be asleep in the garden. This article will review steps you should be taking now in your flower or vegetable gardens to set the stage for a successful growing season. April is the month when we can finally spend time out of doors, breathing fresh, cool air and watching plants and trees “green up.” April is also the month to get your garden in gear for the season. But do so slowly. Starting too early can compact the soil and disturb pollinators that may still be asleep in the garden. This article will review steps you should be taking now in your flower or vegetable gardens to set the stage for a successful growing season. Garden Clean Up The Minnesota garden in early spring is not impressive looking. Bunches of dead plant stalks, soggy leaves, and lots of brown. The temptation is to start cutting down the brown to make room for green growth as soon as the snow melts. But don’t ! During the winter, our dead, brown yards are actually playing host to dozens of pollinating insects. As longer days arrive, they emerge from their winter homes – underneath leaves, in hollow plant stems, and underground – and begin their critically important work for our food chain. When can you start cleaning up the mess? Most insects will not emerge until temperatures are consistently about 50 degrees. In Minnesota, this could be mid to late April or even early May. Of course, you may need to move some winter debris, for example, if leaves are smothering your grass. But be selective and let old plants and leaves rest for a while longer. Lawn Care Late spring and early fall are good times to fix bare patches in lawns. Cooler temperatures are ideal for germinating new lawn seed. Temperatures between 55-65 degrees are ideal for new lawn growth. Pre-emergent applications to control crabgrass or weed seed germination should be done mid-April to mid-May. Do not apply a pre-emergent to newly seeded lawns or gardens (pre-emergent prevents seeds from germinating). Hold off on fertilizing lawns until May when lawn growth begins to take off. Perennials Cut back any perennials that you left standing last fall. It is also the time to divide your established perennials as they begin to emerge from the ground. For many perennials, division helps the plant perform better because there is more space for roots to grow and absorb nutrients and water. (Hint: if you see a hole in the center of your hosta, it wants to be divided!) Plant division is also a cost-free way to expand your garden. Check out https://extension.umn.edu/planting-and-growing-guides/dividing-perennials for more information about how to divide perennials. Soil Testing Spring is the time to prepare your garden soil. Good soil is the foundation of a healthy lawn and garden. Spring is also a good time get your soil tested. Soil testing is available through the University of Minnesota Soil Testing Laboratory . The basic soil test will provide information on the soil texture, organic matter, phosphorus, potassium, pH and lime levels in your soil. With that information, you will know the specific composition of fertilizer that will benefit your garden. It will also provide you with information that will help you determine the types of plants that will do best in your garden. Soil testing is easy! You will fill out a form that asks what the area will be used for and the results will then provide recommendations specific to that use. A soil sample of two to three cups of soil can be mailed or brought to the Soil Testing Laboratory at the University of Minnesota. The sample should be collected by walking in a zig zag pattern through the space and placed in a clean tub or plastic bag. Separate samples should be submitted for separate areas of your yard. Go to this website for specific instructions about how to submit a soil sample and get the latest fees. Preparing the Soil Applying compost to your soil may improve it and help plant growth. Incorporating compost into light, sandy soil helps it hold both moisture and nutrients while adding it to heavy soil improves drainage. If you haven’t applied compost in the fall - and depending on the results of your soil test - adding 2-3 inches of compost and working it into your soil about two weeks before planting may be helpful. Spring is the time to till your soil if that is your practice. Tilling the soil helps to warm it and removes existing weeds. But tilling also stimulates germination of new weeds which should be promptly removed as they emerge. Note that tilling may not be necessary. Take a look at this article for alternatives to tilling. If you do till, it should not be done when the soil is too wet because it may become compacted when it dries. If your soil sticks to a shovel and holds a ball, it is too wet to till. If you are going to add compost or other amendments to the soil, do so before tilling. Planting If you started seeds indoors this winter, you can start bringing seedlings outside during the warmer days of mid to late April (depending on the plant or vegetable) and begin acclimating them to their environment. Remember to watch the weather when hardening off seedlings as extreme wind, sun exposure and cold temperatures can set them back. Spring blooming annuals like pansies and violas can tolerate cooler temperatures adding a pop of color to your outdoor space while we wait for warmer temperatures to arrive. Some cool-season vegetables can be planted outside in mid to late April. The soil must be thawed and easily workable before you plant. Check the soil temperature to determine when cool weather vegetables can be planted. Here are some examples of appropriate soil temperatures for some vegetables: 40 degrees – arugula, kale, lettuce, bok choi, peas, spinach, radishes, radicchio 60 degrees – beans, beets, broccoli, brussels sprouts, carrots 70 degrees – tomatoes, eggplants, peppers, cucumbers, squash, corn melons Cleaning Garden Tools Disease from an infected plant may be spread to a healthy one by using dirty garden tools. Proper cleaning of your tools can reduce the spread of disease. If you haven’t cleaned your tools in the fall, do so in the spring. You should also clean your tools when you have used them on plants that may be infected with a disease. Cleaners such as Lysol All-Purpose Cleaner, a bleach solution and alcohol may be effective cleaners. However, refer to the following article regarding the proper methods to use with these cleaners. The last time you were able to work in the garden, you were raking leaves, cutting down plants, putting garden ornaments away and covering patio furniture. Take pleasure in doing the reverse and watching your garden come alive again.

    < Back Snow Mold! It’s Not About Putting Snow in a Mold As the snow begins to melt, you may start to see a grayish, and sometimes pinkish, circular straw-like, matted patch in your yard, especially near the street where snow was piled up for what may have seemed like decades to some but was only a few months. The spot can also have a “webby” fungus appearance. If you have this phenomenon in your yard, then click on this link to learn about snow mold and what you can do to prevent it from happening again next Spring. Janelle Rietz-Kamenar, Master Gardener Snow Mold is a fungus that develops and thrives when early, deep snow covers the ground prior to the ground being frozen. Snow mold can continue to grow once the snow has melted in the Spring as long as the conditions remain wet and cold. There are 2 types of snow mold found in Minnesota: Gray snow mold produces sclerotia which look like dark, hard round bodies on the grass blade. Pink snow mold produces pink-colored spores and fuzzy mycelium. Areas of your lawn that are affected with snow mold will generally take longer to green up in the Spring but usually come back to normal and therefore, is not usually too serious. In a bad weather year, it can, however, kill the grass. If you want to “spring” into Action this Spring: You can choose to break up and spread the larger snow piles around in the affected areas. This will help the snow melt faster and dry out quicker. You can gently rake the area to create a faster drying process and prevent further mold growth. Preparation to avoid snow mold altogether must be done in the Fall with these easy steps: If your yard is prone to snow mold, skip a Fall nitrogen fertilizer which the fungus thrives on. Continue to mow your lawn until the grass stops growing. Cut grass to 2 inches (but not shorter) to prevent the grass from matting and allowing mold to grow. Rake up leaves If you have certain areas in your yard where snow mold is a problem, consider a snow fence to reduce large piles of snow. While snow mold can be a little unsightly in the Spring, a few actions can help alleviate the problem quickly!

    < 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 Fall Scavenger Hunt by Mary Gadek, Dakota County Master Gardener Come join the adventure of a fall scavenger hunt as a Junior Fall Garden Detective! Teach the child in your life how to detect the arrival of autumn in Minnesota. Read along here for a guide to gathering clues and using some scientific observations in an outdoor search to confirm fall’s arrival. It is time for all Junior Fall Garden Detectives to investigate how we know that fall has returned to our yards and gardens. Let’s find the clues, scientific observations, and evidence your child can collect about fall. Then, participate in a scavenger hunt revealing autumn’s cool air, shorter daylight, and changes in gardens, creatures, and our lives. CLUES As the seasons change from summer to fall, the air temperatures drop and the days get shorter. Look for these clues to determine when the seasons change: ● Air temperatures . The Minnesota average temperatures on September 1 are 77 degrees daytime, 59 degrees nighttime. By November 1, the temperatures have decreased to an average of 50 degrees daytime, 35 degrees nighttime. ● Daylight . From the start of school in early September through the end of September, you may have noticed less daylight each day as you hop on your school bus in the morning until you are playing at the park at the end of the day. Daylight on average decreases by one hour and 15 minutes from August 1 through October 15. The equinox is when the days and nights are said to be equal in length for the entire globe. For the Northern Hemisphere, (the northern half of the world), where Minnesota is located, the fall equinox will be on September 22, 2024, at approximately 7:43 am, kicking off the start of the season. EVIDENCE Some scientific observations, or evidence, of the seasonal changes may include: ● Trees . Trees and bushes are dropping an array of leaves with bright reds, yellows, oranges, and browns. Burning bush (or Euonymus alatus), along with oaks and maple trees create intense red leaves. River birch and yellow poplar trees have showy yellow displays in the fall. ● Plants. Flowers and plants around the yard have lost their blooms and dropped their leaves as their energy returns to their roots below the ground. The final fruits of many plants are ready for harvest, like apples and pumpkins. ● Creatures. The arrival of fall invites the creatures in your yard, or local park, to either migrate to the warmer south or prepare to hunker down for the Minnesota winters by making nests or dens. Birds, like Canadian geese, wood ducks, and the loon, form flocks and fly south. Look up to the autumn sky as the migrating birds fly in a triangular formation to head to warmer locations. Butterflies, like the monarch, partake in a long journey to winter in warm Mexico. You may notice that the butterflies are no longer to be found in the garden. Other animals, insects, and birds remain in Minnesota during the winter by hibernating, or sleeping, in covered areas or under the brush of the colorful fallen leaves and nearby evergreens. Look closely, squirrels are collecting seeds and acorns to save up for their winter meals. SOLVE Now, it’s time for a fun expedition outside in your yard, neighborhood, or local park to search for these clues and evidence of fall and its impact on our daily lives. See the attached printable Junior Fall Detective Scavenger Hunt here for an activity for your child.

Unless you live in New Mexico, Arizona, Nevada, or Hawaii, you are probably familiar with creeping charlie. According to the Minnesota Department of Natural Resources , it was brought to the United States as far back as 1672 from Europe to be used both as a source of food and for medicinal reasons. Before the widespread use of hops for making beer, creeping charlie was commonly used for that purpose, thus you may hear it referred to as “ale ivy” among other names, including “ground ivy” or “catsfoot.” A quick internet search will provide an abundance of websites claiming creeping charlie provides relief from a number of ailments from ringing in the ears to constipation to colic to bronchitis, and the list goes on and on. The internet, however, is lacking scientific research to support those claims. One thing that is certain is that creeping charlie is in the mint family. Being in the mint family, some fans of creeping charlie enjoy making tea from its leaves, or using them in salads, or cooking them similar to how spinach is prepared. Rather than harvesting creeping charlie for its flavor profile, it is much more likely that you are not fond of the plant and spend an enormous amount of time and energy trying to eradicate it from your lawn or garden. There are a number of reasons creeping charlie is not welcome in a lawn or garden setting. Like the University of Minnesota Extension tells us, creeping charlie spreads or creeps across the top of the ground via surface roots or runners, called stolons, creating a dense carpet. The University of Michigan tells us that, similar to the runners above ground, creeping charlie has a rhizome root system that spreads horizontally below the ground. It can also spread by seed and even by small scraps of plant material dropped on the ground or left in the soil. It is a master at taking over areas where other plants are unsuccessful, like shady, moist areas, or where soil is compacted and only weeds tend to grow. Once established, it is very adaptable and has no problem creeping its way into sunny locations as well. It crowds out grasses and other desirable native plants. In order to get creeping charlie back under control, it is important to recognize the plant in your yard. According to the University of Michigan , this herbaceous perennial can be recognized by its square-shaped stems, scalloped opposite leaves, and bilaterally symmetric purple flowers that bloom from April to June. You may notice the dense carpet of the leaves that the University of Illinois describes as somewhat kidney-shaped with rounded, toothed margins. Before discussing how to get rid of creeping charlie, it is important to look at cultural control methods for how to prevent it from taking over in the first place; or at least how to create an environment that is not as conducive for its growth. One thing a gardener can do to prevent a creeping charlie takeover is to plant a shade tolerant grass in shady areas instead of a sun-loving Kentucky bluegrass, for example. The University of Wisconsin alternatively recommends foregoing grass in difficult shaded areas and instead planting other shade-loving plants like hostas, pachysandra, or vinca. Once alternative plants are established, newly introduced creeping charlie would have a more difficult time competing. Another cultural method to prevent or hinder the spread of creeping Charlie, would be to alter the growing conditions. Improving drainage or watering less makes the area less desirable for creeping charlie. The University of Minnesota also suggests reducing the amount of shade by trimming shrubs or pruning trees. Mechanical methods of getting rid of creeping charlie include hand-pulling the plants. The University of Michigan reminds us that it will take diligence and patience to remove all of the plants. The most important thing to remember about this method is to get rid of every piece of the plant. Since any little piece left behind can sprout a new plant, it may take multiple seasons to clear out an area. With that in mind, mowing an area of creeping charlie can cause it to spread if the plant is mowed and the clippings are left behind. Remember to bag clippings when mowing an area that is infested with the plant. The Minnesota DNR also recommends setting the mower at a taller setting and fertilizing less to help choke out the creeping charlie. Physical barriers, like edging, are not very effective in stopping the spread of creeping charlie. The stolons above ground and rhizomes below ground are very adept at finding their way over, under, or around barriers. However, if there is an area where you have decided to let creeping charlie live in your yard, a physical barrier will at least slow the spread as long as you are diligent about keeping it contained and removing any plants that make it past the barrier. If none of the previous methods are reasonable or successful in your situation, it is time to consider herbicides, though, as the DNR states, herbicide control is challenging because creeping charlie can reestablish quickly after post-emergence treatment. The University of Minnesota makes the point that the timing of herbicide application makes a difference in its effectiveness. They recommend fall as the best time to apply it when the plant is taking up nutrients from the soil in order to survive winter. Purdue University adds that in the fall a very careful spot application is less likely to affect surrounding garden plants than in the spring when they are more actively growing. The next choice is spring when creeping charlie is actively growing if there are no surrounding plants or if they are shielded from the herbicide. The most effective herbicide against creeping charlie will contain the ingredient triclopyr. Also mentioned are 2,4-D and Dicamba. These are all selective broadleaf herbicides. This means that if you are treating creeping charlie in your lawn rather than in a garden, you do not need to worry about killing your lawn grasses as it will only kill the creeping charlie. Two - three applications per year should be sufficient to keep it under control if instructions are carefully followed, though the University of Wisconsin warns against applying Dicamba more than twice per year. In the past, gardeners touted the use of Borax to treat creeping charlie. Research at the University of Wisconsin and Iowa State University have proven that it should not be used as broadleaf weed control against creeping charlie or any other weeds. It was found that even in small amounts, it is bad for the soil, providing an unfavorable growing environment for desirable plants. If you have a large area where creeping charlie has completely taken over, you may want to consider one of these solutions. One method recommended by staff at the University of Michigan is called sheet composting, or lasagna composting. Layers of organic material are placed upon newspaper or cardboard to smother the creeping charlie and give you a fresh start. In a sunny location, the University of Minnesota recommends another natural method called solarization, where a sheet of plastic over the infested area for several months raises the temperature so that the creeping charlie can no longer survive. If you prefer a chemical alternative, the University of Minnesota suggests that if your lawn is at least 50% creeping charlie, you may want to apply a non-selective herbicide containing glyphosate, like Round-Up. It will kill all the vegetation. As with all chemicals, be sure to carefully follow the instructions to safely apply it and to see when it is safe for people and pets to enter the area and when you can re-seed the area. Everyone’s situation is different, so it is important to consider all the different options for ridding your lawn and garden of creeping charlie. Everyone’s tolerance level is different, so one last thing to consider, but definitely not the least, is whether or not you can live with creeping charlie. Keeping our neighbors happy and controlling invasive weeds from spreading across the property line is important, but perhaps you have an area in your yard where you can allow creeping charlie to co-exist with you. It does provide a small benefit to pollinators, and the carpet of delicate purple flowers in the spring is a beautiful sight. Photo credits: Lisa Olson (1, 3, 4), University of Minnesota (2, 5)

    < Back Discover Delicata Squash? Delicata Squash is favored for its delicate, edible skin. No peeling necessary! This squash is booming in popularity. Here are some growing tips. Janelle Rietz-Kamenar, Master Gardener So what is delicata squash anyway? It is an oblong shaped squash with green or orange lines running from end to end. It is actually classified as a winter squash but has a thin skin (similar to summer squash) that can be eaten. The delicate skin is the basis for its name. Even though it is technically a winter squash, it does not store as well as other winter squash though because of its skin. It is a cultivar of the species called Cucurbita pepo . Other common names for this squash are peanut squash, Bohemian squash, or sweet potato squash. I have to admit that I had never even heard of Delicata Squash until last year when I learned that 228 Master Gardeners from 49 counties across Minnesota conducted seed trials on this plant. Six different varieties were tested. Master gardeners were looking for the best germination rates, how well the seeds grew, which ones tasted best including texture, and insect and disease susceptibility, as well as a few other factors. Click here to learn more about how this particular squash type performed. This squash appears to be growing in popularity since Cornell University’s Plant Breeding department developed a non-hybrid open pollinated variety around twenty years ago which was more mildew disease resistant. Master Gardeners across the state found it was easy to grow. What some of us didn’t know was what to do with it once harvested. Delicata squash is primarily roasted but can also be steamed, sauteed, and microwaved. Some recipes call for the squash to be stuffed with meat or other vegetables. I knew it was becoming popular when Country Living had an article on “31 Ways to Use Delicata Squash for Dinner Tonight” (October 22, 2021) among other websites/magazines. Delicata squash is a good source of dietary fiber and potassium but not as rich in beta-carotene as other winter squashes. However, if you want to try something different, consider growing this product in your garden this year. Sow seed in the garden in late May to early June, or start seeds indoors in late April. Make sure to pick squash before a hard freeze.
