< Back Square Foot Gardening Do you want to grow vegetables in your garden but you don’t have a lot of space or you only have one sunny spot or your soil isn’t conducive to growing or you just want a few vegetables for your family? Square foot gardening may be your answer. This approach will save time, work, space, and water. And, you will produce some delicious vegetables for your family. Read this article for more information about why square foot gardening may be for you and how to get started. Mickey Scullard, Dakota County Master Gardener With a short growing season, gardeners want high yields of fresh produce from their vegetable gardens, yet many people have limited space suitable for growing. “Square Foot Gardening” is a method of gardening with the underlying premise of producing a greater variety of vegetables in a small space. It is also intended to make gardening more accessible to a greater number of people. According to the Square Foot Gardening Foundation website , this method is, “estimated to cost 50% less, use 20% less space, 10% of the water, and 2% of the work”. They state there will be almost no weeds and you save time and effort because you don’t have to dig, rototill, or use heavy equipment, and fertilizers aren’t needed. It almost sounds too good to be true! However, many people have used this method successfully for 25 years. In the U.S., our standard gardening approach is to plant in rows. This is how many of us have done it for generations, passed down through our families. We have developed tools that support this approach for watering and weeding between the rows, using mulch papers or rototillers small enough for a row. We have row markers, seed tapes, and many other gardening supplies that support the row gardening approach. According to Bartholomew, this approach makes gardening harder than it needs to be with much of the growing space given over to aisles between the plants, resulting in a need to constantly weed those non-growing areas. He also argues that planting in rows results in overplanting. He uses the example of planting cabbages, suggesting few people find it useful to have 30 cabbage heads ripening at the same time. Square foot gardening suggests a different approach that carefully spaces plants to efficiently use space, manage the size of the harvest, and allow for successive planting, e.g., growing multiple crops in one growing season. Instead of sowing seeds and then having to thin the plants, this approach suggests placing the seeds at the distance you’d thin the plants. For example, if the seed packet says thin to 6 inches between plants, you can just space your seeds out that distance in all directions within the square. You can put a ‘pinch’ of seeds in each planting site to increase the chances of germination and instead of thinning, snip out the unneeded plants. This lessens the chance of disturbing or weaking the roots of the plant you are keeping. Most square foot gardens are 4 feet x 4 feet raised beds. They can be other sizes; however, you will want to make sure you can reach all areas of the bed without stepping on the soil. Stepping on soil compacts it, which makes it more difficult for plants to grow. The soil in the raised bed should be a mix of compost, vermiculite, and peat moss. The location of the square foot garden is important, with sufficient sunlight important and access to a water source. Bartholomew suggests placing it near the house so you always have a visual on your growing plants. Within the 4 x 4 space (or whatever size bed being used), a grid of 1 foot x 1 foot squares are laid to mark out each plot. In a 4 x 4 bed, you will have 16 squares in which to plant. The number of plants or seeds you grow in each square is dependent on the full size of the vegetable or flower. For example, in the 1 ft x 1 ft square, you could grow one tomato, or four heads of lettuce, or eight bunches of swiss chard, or sixteen carrots, or thirty-two radishes. Once you have harvested the vegetable, a new crop can be planted. Since one of the other premises of Square Foot Gardening is reducing the need for fertilizer, Bartholomew says you only need to add a shovel of compost prior to each new planting. Square foot gardening will meet the needs of many gardeners. However, those wanting to produce large harvests for canning, freezing, and other methods of preserving, may not find they get the quantities they want using this method. For those wanting a manageable amount of produce, this may be a great way to help limit the amount grown, although if you grow a zucchini plant, you will probably still need to sneak around after dark ‘bestowing’ your bounty on your neighbors’ doorsteps.

< Back Find Plants for Tough Sites Have you ever fallen in love with a plant that you know in your brain won’t grow in your garden but your heart made you buy it anyway? You bought that sun-loving plant and planted it – full of hope - in your shady garden. Didn’t work out? Unfortunately, wishing, and even tender loving care, can’t make a plant grow if it is in the wrong garden space. Fortunately, this article tells us about a resource that can help you find just the right plant for even tough garden sites. Janelle Rietz-Kamenar, Dakota County Master Gardener Over my many years of gardening, one of the most important, yet difficult lessons that I seem to have to re-learn time and time again, is that a plant will thrive best if it is planted in a location where it gets the type of sun, moisture, and soil required for its species. It is so tempting fall in love with a sun-loving plant and convince yourself that you can make it grow in your garden – the one that is all shade. Unfortunately, wishing, and even tender loving care, can’t make a plant grow if it is in the wrong garden space. For those of us whose gardens consist of poor soil conditions or natural landscape impediments, it is especially difficult to find plants that will be successful. So, how do you know which plants will thrive in your clay or sandy soil or on your steep backyard slope? Finding the right plants for your area can be challenging, but not impossible. Fortunately, the University of Minnesota Extension has produced a free, easy and thorough reference guide that can help you meet the challenge. Click on this link to access “The Best Plants for 30 Tough Sites,” written by Minnesota Master Gardeners and Extension Educators Mary Meyer, Deborah L. Brown, and Mike Zins. The reason why I like this guide so much is that it provides extensive lists of plants and their characteristics for those areas that can be limiting. Rather than waste money buying plants that do not fit your situation, use this guide to find plants that can grow successfully. The reference guide covers: Alkaline Soil Annuals 3 Feet or More Annual Vines That Grow Quickly Boulevard Gardens: Perennials and Small Trees Broadleaf Evergreens Clay Soil Cold Tolerant Annuals Compacted Sites: Trees Crevice Plants Deer Resistant Plants Dry Soil: Annual Foliage Plants, Shade or Under Trees and Trees Fragrant Annuals, Perennials, and Shrubs Indoor Low Light Knot Gardens Lakeshore Native Plants Long-Blooming Perennials Rain Garden Plants River Banks and Canoe Public Access Areas Self-Seeding Perennials Septic Mound Plants Shade: Shrubs, Small Trees, and Tall Perennials Steep Slopes Trees That Produce Minimal Litter Under a Black Walnut Tree While the guide does not show a picture of each plant, it does provide you with a place to start looking. I have used this guide many times and I hope it helps you find that perfect plant for your landscape.

< Back Moving Houseplants Outdoors for a Summer Vacation Linda Stein, Dakota County Master Gardener You have been enjoying your indoor plants during our long, cold winter. But soon it will be time to think about transitioning some of those plants outdoors. March might seem a bit early to think about moving your indoor plants to the outdoors but plants do require a transition time and warm weather will be here sooner than you think. There are many reasons that you might move your houseplants outdoors for the summer. But there are several things to consider to ensure that your plants flourish as a result of this move. As we plan our outdoor gardens, we consider which plants can survive in the different environments in our yards, taking into account the amount of sun and the type of soil. When we obtain plants for inside our homes, we are selecting plants that can survive in the environment inside our homes. These plants do not require full sun. But they can definitely benefit from a visit outdoors. Why would you want to bring your houseplants outdoors? Sun First of all, the plants can benefit from the stronger sun rays. The strength of the sun’s rays is significantly stronger outdoors even than the sun a plant receives when placed by a south-facing window. Easter Cactus moved outdoors bloomed for the first time Rain Secondly, the plants can benefit from rainfall. Slightly acidic ph is better for overall soil health and makes nutrients more available. Rain water generally has a ph between 5.0 and 5.5. (The acidity scale runs from 0 to 14 with lower levels indicating high acid levels and higher levels more alkaline.) The acidity of tap water varies among communities but generally has a ph between 6 and 8.5. So, the acidity level of rain can strengthen plants. Rainwater also contains nutrients that can benefit the plants themselves. In addition, rain can wash the dust and other particles that have been collected on your houseplants. They’re Pretty! Finally, houseplants can be used to beautify your deck or patio and eliminate or reduce the need to purchase plants that you will discard at the end of summer. The plants can also be incorporated into your garden, either directly in the ground or by placing the potted plant among your outdoor plants. Things to Think About Temperature : The move outdoors shouldn’t begin until the temperature is above 50 or 60 degrees. Phases : Make the move in phases. First move all your plants to a shady area, even those plants that can benefit from stronger sunlight. Keep plants that prefer shade (those plants that weren’t kept near a south-facing window), in this location. Other plants should be moved to a sunny location over the course of a week or 10 days. Water : Plants do require a difference in care outdoors than indoors. First of all, plants grow more quickly during the summer months and this growth spurt will generally be intensified when plants are placed outdoors. Therefore, plants will require more water and more fertilizer. The amount of water and the frequency of watering will depend on the type of plant, the type of pot (clay pots are porous and therefore moisture will escape through the pots while water in plastic pots can only be absorbed in the soil and can only escape through drainage holes), and other factors such as the amount of rain and humidity. Water your plants on their schedule, not yours. Check to see if your plant needs watering by sticking a finger about ½ inch into the soil. If the soil is dry, water. Fertilizer : House plants should not be fertilized during the winter months. During those months when there is reduced light and temperature, they experience reduced growth. However, they will benefit from fertilizer during the summer months. This is particularly true if the plants have been moved outdoors. Be sure to use fertilizer that is labeled for indoor plants and follow the instructions on the package regarding the amount and frequency of application. Too much fertilizer can result in a buildup of salts and excessive, leggy growth. Repotting : When outside you might want to repot those plants that have become root-bound so you won’t create a mess indoors. Some signs that your plant may need repotting include, roots growing through the drainage holes, the plant becoming top-heavy, or the plant growing slower than in the past. When transplanting to another pot, the new pot should only be 1-2 inches larger than the original pot. The Negatives Keep in mind things that might negatively impact your plants. Large rainfalls and heavy winds might have adverse effects on plants. Remember to consider the amount of rainfall the plants experienced when deciding when your plants need watering. Watch for heavy winds that might cause large or top-heavy plants to fall over. Watch for signs that your plants are sun-scorched. Indications of sun scorch are leaves that become brittle and turn yellow or brown. Generally, if caught early, you can remove the impacted leaves and move the plants to a shadier location. Watch for pests that might set up household on your plants or the pots holding your plants. Many of these pests don’t harm your plants, but you will want to eliminate them before moving your plants back indoors. Photo Credit: Carol Fuerstneau (1), Linda Stein (2, 3), Steve Greenstein (4)

< Back History of Minnesota’s Successful Apple Research Breeding Program Apples - one of the joys of autumn! Wandering through apple orchards is a favorite activity for Minnesotans. And at the end of the day, there is the pleasure of eating the apples we have collected in so many different ways. But did you know that the University of Minnesota is one of the leading apple research and breeding programs in the U.S.? Without the intense desire of early Minnesotans to have access to apples and the commitment of early apple breeders, we would not be enjoying Honeycrisp, Zestar®, SweeTango®, and First Kiss® as well as the many older varieties still available. Mickey Scullard, Master Gardener When people moving from the east coast settled in Minnesota, they brought with them their apple trees. To their dismay, the trees did not survive the Minnesota winters. This dilemma prompted Horace Greeley, editor of the New York Tribune newspaper, to say, “I would not choose to live in Minnesota because one cannot grow apples there”. Minnesota apple growers rose to the challenge. Peter Gideon, from Excelsior, was the first director of the State Experimental Fruit Breeding Farm. In 1968, he produced “Wealthy.” It is still available, but not easy to find. The incredibly successful apple research program at the University of Minnesota (UMN) is one of the oldest continuous programs in the U.S., beginning in 1878. Samuel Green, the first professor of Horticulture, moved operations from Excelsior to the St. Paul UMN campus. In addition to advancing apple research, Green catalogued the hundreds of apples that amateur growers had been creating across the state since the mid-1800’s. This was one method he used to further a systematic apple breeding research program. Green edited a book, called Apples (available in the public domain, Apples ), that contained a list of apples, written by John S. Harris. Harris was an amateur apple breeder who was also an officer of the Minnesota State Horticultural Society. The book described key characteristics of the apples and the apple trees he found on homesteads and farms across the state. These characteristics included growing challenges, tasting notes, and information about the ancestry of the tree. Some included drawings of the apple. Examples from the book: Coates Seedling Size 2; form, round conical; color, yellowish green with light blush on sun side, skin shows many grayish dots; stem, short; cavity, small; calyx, closed; basin, irregular, shallow, corrugated; flesh, fine, greenish white; flavor, pleasant, sub-acid. Season January to March. Originated in Dakota County, Minnesota. Early Glass Size 7 to 8. form, round, angular flat, slightly ridged; color yellowish green, with light spots showing through the skin; flesh, nearly white, a little coarse and loose; flavor, mild acid, not rich; stem, short and stout in a medium irregular broadly russeted cavity; calyx, half open in a medium deep, ribbed basin; core, open. Tree is erect and vigorous. Season, August. Origin, Russia. The first apple developed in the research program, named “Minnehaha,” was released in 1920. According to the National Fruit Collection, Minnehaha had ‘rather soft, coarse flesh with a subacid, slightly sweet flavor”. Minnehaha apple The fourth apple introduced was “Haralson” in 1922. This apple is still widely available and a favorite of many people to this day. Haralson apple With apple research going back over 100 years, one might wonder why there have only been 30 new varieties. Producing a viable, hardy, and good tasting apple does not happen overnight. The process of developing a new apple can take 20 to 30 years. When the research program began, researchers collected parent trees from the wild and from growers in the Northeast and the Midwest. These were crossed and new trees containing the characteristics of the different trees were grown. The successful new tree seedlings were crossed with other apple trees that had favorable characteristics. This process was repeated until the trees produced were hardy and had good growing characteristics and more importantly, produced apples with good taste, texture, and appearance. The apple research program in Minnesota is only one of three in the U.S. The other two programs are at Cornell University in New York state and Washington State University. Without the intense desire of early Minnesotans to have access to apples and the commitment of early apple breeders, we would not be enjoying Honeycrisp, Zestar®, SweeTango®, and First Kiss® as well as the many older varieties still available like Beacon, Redwell, Prairie Spy, Fireside, Honeygold, and State Fair . This year, 2022, the UMN’s program released Triumph® . Trees are available in limited quantities and we won’t likely see these apples available widely before 2025. Triumph apple If you’d like to learn more, the Minnesota Historical Society has additional information on the history of growing apple trees in an article titled, “Minnesota Apple Trees” at http://collections.mnhs.org .

< Back April Bring Us – Asparagus! Julie Harris, Master Gardener If you are lucky enough to have an asparagus bed in your garden, you will probably be able to start harvesting this tasty vegetable in April. And look for fresh asparagus in the stores in April, as well. There are so many fantastic ways to eat asparagus – raw or cooked. But here is our family favorite recipe. Asparagus is one of few perennial vegetables suitable for growing in Minnesota gardens. If you are lucky enough to have an asparagus bed in your garden, you will probably be able to start harvesting this tasty vegetable in April. And look for fresh asparagus in the stores in April, as well. If you would like to start an asparagus bed this year, you should plant between early May and early June. An established bed can provide you with delicious and tender harvests for 15 years or more. There are many ways that you can use asparagus, of course. I ran across this recipe several years ago and it has been a family favorite ever since. Cheesy Asparagus Salad 2 ½ pounds fresh asparagus (white or green, or mix) 1 teaspoon of salt 3 tablespoons olive oil 2 teaspoons white wine vinegar 1 teaspoon kosher salt ½ teaspoon black pepper 1 ounce fresh thyme (or to taste) 1/3 pound Jarlsberg cheese or Swiss cheese, shredded ¼ cup spicy sprouts, optional Trim asparagus and break off thick ends. Place asparagus in boiling water with 1 tsp. salt; reduce heat and cook for 4 – 6 minutes. Cook until crisp-tender. Plunge into cold water to chill. Meanwhile, combine olive oil, vinegar, kosher salt and pepper. Remove leaves from 2/3 of the thyme stems; coarsely chop leaves and add to olive oil mixture. Place chilled asparagus on a platter; pour dressing over asparagus. Garnish with Jarlsberg or Swiss cheese, remaining thyme and spicy sprouts.

< Back Protecting Our Trees from Invasive Species Dan and Cheryl Forrest, Master Gardeners The Minnesota Department of Natural Resources defines an invasive species as “species that are not native to Minnesota and cause economic or environmental harm or harm to human health.” This article defines and identifies the invasive species that can cause harm to the economy, environment, or human health. The Minnesota Department of Natural Resources defines an invasive species as “species that are not native to Minnesota and cause economic or environmental harm or harm to human health.” We’re looking at a two part definition. In the first part we see that these species are not native to Minnesota. We often use such terms as exotic, alien, introduced, etc. There is an implication that all invasive species come from outside the United States. This is not always the case. These new pests simply come from outside Minnesota. In the second part of our definition the key word is harm. We are concerned with those pathogens, plants, animals or insects that can cause harm to the economy, environment, or human health. Emerald Ash Borer (EAB) The number one new pest facing our trees in Dakota County is the emerald ash borer (EAB) . The nearest confirmed sighting is in the area of Fort Snelling in Hennepin County and Highland Park in Ramsey County. The general rule that the insect can travel by itself somewhere between 13-15 miles in a given year implies that within a short period of time we will have confirmed sightings within Dakota County. Do you know the symptoms to look for? The first thing to look for is increased woodpecker activity. These birds know a tasty treat when they find one. This increased activity normally happens in the second year after EAB infestation and is followed by vertical splits in the bark and sometimes defoliation in the tree canopy. A closer inspection could then reveal the large s-shaped galleries under the bark and the D-shaped exit holes. These symptoms generally confirm that the tree has been infected. Gypsy Moth The second pest that we all need to be aware of is the gypsy moth . It attacks several varieties of trees but here in Minnesota aspens and oak seem to be the favorite. The gypsy moth caterpillars are capable of defoliating acres of trees. It has arrived in Minnesota! Not necessarily here in Dakota County, but it has invaded out state. Lake and Cook counties in the Arrowhead region have reached the point where they will be experiencing the first steps in a quarantine . How will it affect us? Most of us will not be directly affected. But if we have property in these counties or intend to vacation there we will feel the impact. Thousand Canker Disease Thousand Canker Disease is a third new pest that affects black walnuts. It is a fungus carried by the walnut twig beetle. When it enters the bark it leaves behind a fungus that causes a canker. If you have any black walnut trees you need to be concerned and be able to recognize it. For the rest of us you do need to know that it is now the law that black walnut wood of any size or shape cannot be imported into Minnesota. A quarantine is in effect that makes this illegal. Asian Longhorn Beetle The fourth pest emerging in Minnesota is the Asian Longhorn Beetle . While poplars, maples and box elders seem to be the preferred trees in Minnesota it also feeds on several other varieties which makes it especially dangerous. Signs and symptoms include crown die-back, shallow depressions in the bark where the eggs are laid, sap seeping from these egg niches, pencil-size round exit holes and a sawdust on the top of branches or on the ground surrounding the tree. Brown Marmorated Stink Bug Two new and emerging pests do not actually kill the tree but both will damage the fruit the tree produces. The first is the Brown Marmorated Stink Bug . It has been found in several Minnesota counties and is considered a pest because it feed on fruit and vegetables. The insect is also considered a nuisance as it invades houses and other buildings in the fall seeking warmth. When disturbed, it emits a foul odor. Spotted Wing Drosophila Spotted Wing Drosophila (SWD) is also a new and emerging pest and has been found in 20 counties in Minnesota. It is similar to a fruit fly. But unlike the typical fruit fly that feeds on damaged fruit, SWD feeds on intact, healthy, ripening fruit, especially thin-skinned berries. The female can pierce the soft skin and lay its eggs. In doing so there is also a possibility of an introduction of rot and fungus. So far in Minnesota the favorite has been raspberries. It has been known to attack apples and other tree bearing fruits. Oriental Bittersweet In our training one invasive plant was discussed. Oriental Bittersweet has been found in Dakota County in Burnsville and Eagan. It is a vine that can grow over 60 feet long and will girdle and smother trees and shrubs. It is spread by rhizomes and seeds, mainly through birds ingesting and then eliminating the seeds. Through this natural action, entire plant communities have been known to be overwhelmed. iI becomes our job to eradicate it. What Can I Do? We still need to answer one important question. What should be done if you suspect you have found one of these tree pests? There is an “Arrest the Pest” hotline you can email at arrest.the.pest@state.mn.us or by phone at 888-545-6684. Doing so could help us protect our native trees.

< Back Junior Winter Garden Detectives Mary Gadek, Master Gardener Do you know a child who has wondered where all the garden creatures live in the winter in Minnesota? Help that child become a Junior Winter Garden Detective by gathering clues, using some scientific techniques and then searching outside to solve this chilly mystery. CALLING ALL JUNIOR WINTER GARDEN DETECTIVES! Do you know a child who has wondered where all the garden creatures live in the winter in Minnesota? Help that child become a Junior Winter Garden Detective by gathering clues, using some scientific techniques and then searching outside to solve this chilly mystery. NOTE: Adults can help guide, or work together with, their child through this project. Utilize the books mentioned later in this article to reinforce the information from this article and to assist younger children in learning the concepts. Junior Winter Garden Detectives - Let’s find out where birds, common Minnesota animals, turtles, frogs and insects live in Minnesota winters. Some creatures migrate, or move, to a warmer part of the world in late summer or fall. Many others remain here in Minnesota. But, where are they all? Often, they are not so easy to see. By READING the clues from the information below, you will be able to solve the case of the hiding winter creatures by looking in your own backyard or neighborhood park. THE CLUES BIRDS - When the cold and wind of a Minnesota winter settles in, watch for birds to make a roost and group together in the holes of trees, next to trees or a thicket of pines . Insect eating birds fly South for the winter so they can eat insects from open water in warmer climates. The remaining birds can survive on the seeds, berries and garden waste found in our yards and parks during the cold weather. Sometimes people leave seed in bird feeders to help these birds survive during the cold days. Just like humans, birds keep warm with their down coat; that is, their feathers. Some common Minnesota winter birds are cardinals, finches, blue jays and woodpeckers. DEER AND SQUIRRELS - Look around and you will see many animals, including deer and squirrels, in your local landscape. Deer stay active and hang out by stands, or groups, of pine trees . These trees, called conifers, keep their needles all year round so snow can easily collect on their branches and keeps the forest floor warm and dry underneath for a cozy gathering spot. The common gray squirrel can be seen occasionally popping out from their nests in tree cavities or leaf and piles collected from trees in the fall and thickened by moss. You can view the squirrels scampering around nearby their nests to retrieve the food they hoarded in the fall, foraging on pine cone seeds, or stealing from the bird feeder in your yard. TURTLES AND FROGS - Keep a sharp eye open for turtles hibernating, or sleeping all winter, at the bottom of a pond or lake, digging themselves into the mud of the water's bottom , where the temperature stays warmer and more stable than up at the top of the water's surface. Frogs can be found in two different areas, depending on the type: 1. Aquatic frogs hibernate in the water near the bottom of the stream or pond where they breathe oxygen from the water through their skin; and, 2. Tree and wood frogs become dormant under leaves and plants from the past growing season in our garden and then freeze solid for the winter months. These frogs’ bodies use a special process where a natural antifreeze, called glycerol, keeps their organs from fully freezing . Carefully look under some leaf piles and you might see a frog that looks dead but really is just temporarily frozen. How is this possible?! All good detectives verify their clues--see below for more information on this special antifreeze process. INSECTS - Minnesota insects survive winter by migrating, by tolerating the cold or by avoiding the cold. Monarch butterflies migrate 3,000 miles to the warm south. The Banded Woolly Bear caterpillar tolerates the cold by becoming dormant underneath leaf litter and a blanket of snow, similar to the tree and wood frogs, after producing special antifreeze called glycero l, which keeps its cells from bursting when they freeze. (See the scientific process below). Bees hibernate in winter in one of three ways: in the ground, in flower stem cavities or, for bumble bee Queens, under leaves and brush. Most bees in Minnesota are ground nesters who burrow into bare soil to stay warm in winter and lay eggs for spring. Look for a small ¼-½ hole for a tunnel in the soil without a lot of plant cover to get a glimpse of where a bee might be in its winter slumber. You will need to wait until spring before you see a bee emerge! Some other bees take winter shelter and lay eggs in the hollow of flower stems . A garden left for a spring cleanup, instead of in the fall, will reveal hollow stems where flowers once were. Imagine bees and their eggs resting, safe from the harsh winter conditions. Bumble bee queens prefer to tuck into leaves or brush left in the garden, often near pollinator plants. The workers have died in the fall, while the Queens are left to start new colonies in the spring. READ READ these children’s books to do additional detective work with your child to see how creatures live in winters. Winter Dance by Marion Dane Bauer, tells about a red fox's discovery of how to live in the winter while learning about what some other creatures do for homes in the winter. Available at the Dakota County libraries. ISBN: 9780544313347 or, buy at Amazon : Over and Under the Snow by Kate Messner and art by Christopher Silas Neal, takes you along a cross country ski family adventure to what creatures are out and about in the winter. Available at Dakota County library. ISBN: 9780811867849, or buy through Amazon : DO EVIDENCE: WHAT IS IT LIKE FOR THE FROG AND BANDED WOOLLY BEAR CATERPILLAR TO HAVE ANTIFREEZE Once you gather all your clues, every good detective verifies the clues. Our clues show an amazing antifreeze process for tree and wood frogs and the banded woolly bear caterpillar, which allows these critters to live in the Minnesota winter. Using your detective skills, let’s do the following experiment to see what the antifreeze is like in the frogs and caterpillars. Supplies Any Gelatin Hot water from tap (not boiling), amount used in gelatin instructions Small paper cups (or small ziplock bags) Tablespoon Directions Follow the instructions to prepare the gelatin, but using warm water (not boiling). Fill a paper cup with about 1 tablespoon of the prepared gelatin. Put the cup in the freezer for about 20 minutes. (The antifreeze process for frogs occurs in about 20 minutes). When the time has elapsed, take the cup out of the freezer. You will notice the gelatin is part frozen, part liquid. The mixture is similar to the liquid in the organs of these creatures that stays cold but not frozen so they can survive being dormant in the winter. SOLVE THE CASE: FIND THE ANIMALS The last step for Junior Winter Garden Detectives is to find the animals or their homes outside! Put on your winter boots or snowshoes and go search to solve the case. Make notes on the checklist provided below or make a photo journal of the winter garden homes you find. JUNIOR WINTER GARDEN DETECTIVE CHECKLIST Check off the creatures you see outside. For the critters that go dormant, use your imagination and find a spot that might be their winter home. Note: Since they are trying to stay warm, it might take a few visits outside before you complete the list. Optional: list where you see them or take a photograph. 1.Birds 2. Deer 3. Squirrels 4.

< Back Using the Last Frozen Vegetables to make Tasty Tacos and Springtime Cake Joy Johnson, Master Gardener It’s May, you may have a few things peeking up in your garden, or maybe you’re like me and nothing is up yet, and nothing is ready for picking. I’m still living off of veggies that I canned, froze or dried last fall. Here is a crowd-pleasing recipe that makes use of my canned tomatoes, frozen corn and ground venison. You can use ground beef or ground turkey too. It also has corn chips on it, and those are a favorite! It’s very easy to freeze fresh tomatoes. Just pull off any stem, wash and put into freezer baggies and put in the freezer. When you’re ready to use them, take them out of the bag and run them under hot water, the skins will peel right off by rubbing them with your thumbs. Cut out the stem spot and chop for your recipe. You’ll have that wonderful garden fresh tomato taste. Corn Bread Taco Casserole Ingredients 2 pounds ground venison, beef or turkey 2 envelopes taco seasoning 2 cups diced canned tomatoes, drained 1 cup water 1 cup cooked rice 1 can (4 ounces) chopped green chiles 2 packages (8-1/2 ounces each) cornbread/muffin mix 1 cup whole kernel corn 1 cup sour cream 2 cups corn chips 2 cups shredded Mexican cheese blend or cheddar cheese, divided 1 can (2-1/4 ounces) sliced ripe olives, drained Topping: Shredded lettuce, chopped tomatoes and chopped red onion Directions Preheat oven to 400°. In a frying pan oven, cook venison over medium heat until no longer pink, 8-10 minutes, breaking it into crumbles; drain. Stir in taco seasoning. Add tomatoes, water, rice and green chiles; heat through, stirring occasionally. Meanwhile, prepare cornbread mix according to package directions; stir in corn. Pour half the batter into a greased 13x9-in. baking dish. Layer with half the meat mixture, all the sour cream, half the corn chips and 1 cup cheese. Top with remaining batter, remaining meat mixture and olives. Bake, uncovered, until cornbread is cooked through, 55-60 minutes. Sprinkle with remaining 1 cup corn chips and 1 cup cheese; bake until cheese is melted, 3-5 minutes longer. If desired, serve with lettuce, tomatoes and red onion. Char’s Springtime Cake Some of you may have rhubarb peeking up, but due to our very cold early spring, I doubt it’s ready to pick. I had one package of rhubarb left from last fall in my freezer. I pick the last of my rhubarb in the fall just before it frosts and I wash, cut it into small pieces, put it in a freezer container and freeze it until early spring, like now, when I’m dying for a fresh spring taste of something from the garden. This recipe was adapted from one handed down to me from my wonderful step-mom who passed away last August, from COVID. Hers calls for all rhubarb, but since I didn’t have that much in the freezer, I substituted frozen strawberries and blueberries for part of the rhubarb. This was taste tested by family and friends and determined to be a wonderful taste of spring and summer! Directions Blend: 1 c. flour ½ c. butter 5T. powdered sugar Mix and press into a 13x9 pan. Bake for 15 minutes, until golden at 350 degrees. Mix: 3 eggs 2 ½ c. flour ¼ tsp salt ¾ tsp baking powder Add: 1 ½ cups rhubarb cut into small chunks 1 ½ cups sliced strawberries 1 ½ cups blueberries Pour over crust and sprinkle with cinnamon. Bake 40 minutes. Remove from oven and sprinkle with powdered sugar while still warm. Photo Credit: Joy Johnson (1,2,3,4)

< 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.

< Back Water Smarter, Not Harder In the “Land of 10,000 Lakes,” it’s hard to believe that some areas of Minnesota may experience shortages of clean water by the end of this decade. Pollution caused by increased population - along with climate change - make water even more precious. Educating yourself about smart watering techniques is the first step toward becoming a good steward of our precious water resource. This article explains how you can be help to protect our water supply. Lisa Olson, Master Gardener You may be wondering why we need to worry about water since we live in the “Land of 10,000 Lakes,” but even here, fresh, drinkable water is a precious commodity and requires energy to clean it. According to the Minnesota Technical Assistance Program , “the wastewater and water treatment sectors account for as much as 3% of electricity use in the U.S. nationwide.” Since it is always there, like a reliable friend, every time we turn on the faucet, it is easy to take this precious resource for granted. In times of drought, even here in Minnesota, the population can deplete aquifers faster than they can be replenished. It is time to appreciate water and learn how to use it more wisely and efficiently - water smarter. Established Lawn and Gardens Water your lawn deeply, but less often. Typical, healthy Kentucky bluegrass lawns, common in Minnesota, need about an inch of water each week, maybe less depending on your soil and conditions. If you have been quick to turn on your sprinkler, the roots of your grass may be very shallow. By letting the soil dry out down to about a 6-inch depth, you can encourage deeper root growth and a more drought tolerant lawn. As Michigan State University reminds us, it is always a good idea to have your soil tested so you can amend it if necessary. Also, check for compactness to make sure the water you are applying can penetrate the ground. By being familiar with what you have, you are better able to meet the needs of your particular lawn, enabling you to make adjustments to the soil so that your watering techniques can be most effective. If you have a built-in sprinkler system, you may be tempted to just set it and forget it, perhaps programmed to match your city’s watering restriction schedule. ( https://extension.umn.edu/lawn-care/water-saving-strategies-home-lawns .) Don’t fall into that category of un-smart waterers! First, set out containers in different locations in your yard to catch the water being supplied by your sprinkler system to educate yourself on how much water you are actually giving your grass. Second, water in the morning before the heat of the day so you don’t lose a lot of water to evaporation. Winds are usually calmer first thing in the morning as well, and morning watering gives the blades a chance to dry off throughout the day to avoid providing a breeding ground for diseases to develop under wet, dark conditions that could occur if you water at night. If you do have a sprinkler system, check into rebates that may be provided by your municipality to residents who install soil moisture sensors. The sensors can be placed into the ground and set to prevent the sprinkler from running if the soil is still damp down to 6 inches below the surface. One other thing you can do to minimize frequent watering of your lawn, is to let it grow to a height of at least 3 inches. The longer stems will shade the roots to prevent drying out too quickly, while at the same time hamper weed growth in the thick, healthy lawn. Auditing Sprinkler System Similar to your lawn, a morning drink of water for your flower and vegetable gardens is a good idea. Watering the plants at their bases is another way to prevent water from sitting on the leaves which could lead to a breeding ground for molds and diseases to take hold. Soaker hoses are ideal for the garden setting to keep water off the leaves. To go the extra mile to conserve water, capturing rainwater in a barrel and reusing it to water your gardens is another smart watering idea. New Lawn and Gardens If you are starting with a blank canvas, preparing to put in a new lawn or garden, you have the opportunity to make some intentional choices during the planning stages that will set you up for success as a smart waterer. As far as lawns goes, while Kentucky bluegrass is a good choice because it has the ability to go dormant during dry spells, do some research about other winter-hardy, drought-tolerant grasses that require little or no watering. You may find a low maintenance lawn that not only requires minimal watering, it may have the added benefit of supporting pollinators. In your gardens, group together plants that have similar watering needs so you can water efficiently only where needed. ( http://www.seattle.gov/documents/Departments/SPU/EnvironmentConservation/SmartWatering.pdf .) When you are making your plant selections for your flower gardens, it is wise whenever possible to choose native plants. Native plants are much more likely to require less water. Remember, they were here before we were and survived without us watering them. Unfortunately, we cannot plant and just forget about them. Depending on soil and runoff conditions, native plants will still need some minimal attention. Want to boost your watering smarts I.Q. even higher? Whether your garden is established or new, applying mulch around your plants in late spring after the soil has warmed will prevent the soil from drying out too quickly. As an added bonus, it will free up your time from having to pull weeds as it acts as a weed barrier. Educating yourself about smart watering techniques is the first step toward becoming a good steward of our precious water resource. If there are youngsters in your life, you can use resources like the Minnesota DNR where you can find fun games to help educate them so we can continue to have fresh, clean water for future generations.
