< Back A Rapid Growing Native Shade Tree: The Birch (Betula spp.) Jim Lakin MD, Dakota County Master Gardener The birch tree is so much a part of Americana and so dear to the hearts of all Northern Midwesterners, it’s a pretty easy sell to suggest adding some to your landscape. But, hold on, there are facts to understand about various types of birch to ensure that the one that you choose will thrive in your yard. This article focuses on three types of birch that are commonly used in Minnesota. So was I once myself a swinger of birches. And so I dream of going back to be. It’s when I’m weary of considerations, And life is too much like a pathless wood… From Birches by Robert Frost The birch tree is so much a part of Americana and so dear to the hearts of all Northern Midwesterners, it’s a pretty easy sell to suggest adding some to your landscape. Mind, this is a full-sized tree and one that will send out roots from which spring a gathering of birches if left to their own devices. In other words, it probably is not a suitable planting for a small suburban lot. If you do have a bit of room, however, within a few years you can achieve a gorgeous stand of grey-white sentinels, rustling softly in the summer wind, gently presiding over the restrained winter landscape. About seventeen species of birch are native to North America. They are rapid growing, reaching as much as 80 feet in height with a spread about half the height. Birches tend to colonize open ground, especially after a fire or other disturbance. In general, they favor light, well-drained, acidic soils as are often seen as pioneer trees after a burn. Of these seventeen, three species are most often used for landscaping: Yellow birch, River birch and Paper birch. Yellow birch ( Betula alleghaniensis ) is found across the Great Lakes into Minnesota. It is easy to grow from seed and transplants well as is true of all three species. It makes a fine shade tree but should be planted in a moist, sheltered site. So, an area to the north or east of the house would be ideal. Once established, the trunk and limbs display a shimmering silvery to copper gray exfoliating bark. Try crushing the buds or stems. They give off a strong scent of wintergreen! River birch ( Betula nigra ) as the name implies is mostly confined to the flood plains and riverbanks of the Midwest. The lower Minnesota River is a great place to look for them. Unlike its sisters, it is primarily a southern Midwestern tree, cold-hardy up to USDA zone 4. Also, it is susceptible to highly alkaline soils. So, keep plantings away from streets and sidewalks with alkaline concrete deposits. It’s not a street tree. It looks great in clumps developing a charcoal grey trunk over time. The younger bark is an attractive exfoliating white, with cream to salmon shades underneath. Paper birch ( Betula papyrifera ) is greatly prized for its stunning white bark. It prefers the cooler Upper Midwest. Unfortunately, many have fallen to the bronze birch borer. Borer-resistant strains have been developed and should be sought in your local nursery. Paper birch requires full sun and requires well drained soil. It makes a dramatic mass planting on the edge of woodlands, its native niche. So, take your pick, depending on your situation. But a word of caution: don’t swing on them. As Robert Frost once admitted, “It was almost sacrilegious, climbing a birch tree till it bent, till it gave and swopped to the ground, but that’s what boys did in those days”.

< 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 Planting for a Fall Harvest Late summer doesn’t always come to mind as planting time. But Late July and early August are great times to plant vegetables that grow quickly and mature better in cooler temperatures. Read on to discover which plants you can plant now that will grow successfully well into fall. Tori Clark, Master Gardener Late summer doesn’t always come to mind as planting time. Some crops like lettuce and spinach can be bitter and hard to grow in the heat of the summer. Late July and early August are great times to plant vegetables that grow quickly and mature better in cooler temperatures. After harvesting veggies like lettuces, radishes, peas and spinach you can easily grow more if you have the inclination for more fresh, garden-grown produce into fall. Before replanting an area remove any remaining plants and allow the area to rest for a couple of weeks. Roots and debris from some plants can cause seeds to not germinate so it is best to wait. Next, remove any weeds, loosen the soil, and add a balanced fertilizer or some compost to replace the nutrients the earlier crop used. Some plants like peas, salad greens, spinach, and herbs such as cilantro and basil grow in as few as 30-50 days and have plenty of time to grow before the first frost. Other vegetables like kale are frost tolerant and continue to grow well into October while being tender and sweet. Whatever you decide to try growing as a late crop be sure to check the seed packages for the number of days to maturity to ensure plants have enough time to grow. The University of Minnesota Extension also has a handy planting chart that shows the types of vegetables best suited to late planting. Photo Credit: University of Minnesota Extension (1)

< 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 Tomatoes the Ubiquitous Summer Vegetable BJ Hansell, Dakota County Master Gardener It’s not too late to plant tomatoes in Minnesota this summer. But, how do you choose from the many, many brands of tomatoes that are out there. Read this article for very useful information about choosing the right variety of tomato to grow in your garden. It’s June, so likely you have already chosen and planted garden tomatoes. If you’re still debating, you’re at the right place. Let’s review of one of the most popular vegetables raised in home gardens. The tomato, s olanum lycopersicum, Lycopersicon lycopersicum is a member of the nightshade family of plants; most of the family are poisonous. Thank goodness for this tasty, safe to consume relative. World-wide there are 10,000 varieties of these delicious orbs. A small percentage perform very well in Minnesota. Our growing season is challenging given the potential for late frosts, and the wide range of temperatures (hot to hotter) over a short period. Tomatoes are almost any color of the rainbow. Sizes range from cherry, about the size of a thumb tip; to beefsteak, regularly at seven inches in diameter with some weighing nearly a pound or more. So many tomatoes, so little time! To help with choosing the optimal for your garden take a look at the results of 2022 tomato seeds trial of six varieties: Brandywine Marriage Tomatoes Below are some general considerations when choosing varietals. To Heirloom or not to Heirloom An Heirloom tomato carries the best characteristics of tomatoes and have been grown for decades. They have been grown without crossbreeding for at least 40-50 years or more. When you choose heirloom varieties you consistently get what you expect. Heirlooms are reportedly easy for the beginner gardener to grow. They are also often considered to be more flavorful. Hybrid, “normal” tomatoes are carefully bred (human intervention) to have particular characteristics. For example, hybrids have larger yields. They also may be bred to be more resistant to pests and disease. Determinate versus Indeterminate Determinate tomatoes grow to a certain point, then stop. They are bushy, compact, of shorter stature, and generally 2-4 feet tall. They still require some support, like tomato cages. They produce all of their tomatoes at once. The fruits develop on the ends of the branches. Determinate tomatoes are usually labeled as “bush,” “patio,” or “container” - perfect for smaller spaces. There are also dwarf types. Since all the tomatoes on the plant mature simultaneously, they tend to have a shorter growing season. In order to have tomatoes throughout the summer, one must either stagger start dates, or consider planting additional indeterminate tomatoes. Indeterminate plants grow and grow. They are the vine tomatoes most recognized and envisioned when people talk about growing tomatoes. They can grow to lengths of 10-12 feet, therefore, require vertical supports, and lots of them. Indeterminate tomatoes produce fruit throughout the season. The fruit grows all along the stems, ripening at different times. This results in a longer growing season and and greater yield than determinate varieties. Regardless of your choices, enjoy the sun-happy tomatoes until the Minnesota frost sweeps them away. Here are two recipes that are often overlooked. First, more than a movie, welcome: Fried Green Tomatoes! Second, the “Southern Tomato Sandwich.” NOTE, Duke’s Mayo is what makes it perfect. Ingredients 2 (½-inch-thick) slices beefsteak tomato ¼ tsp. kosher salt or ⅛ tsp. table salt ¼ tsp. freshly, coarsely ground black pepper 2 slices soft, white sandwich bread 3 Tbsp. mayonnaise, or more!! Directions Arrange tomato slices on a paper towel, sprinkle evenly with salt and pepper. Let stand until tops of slices are beaded up with juices, 3 to 5 minutes. Spread one side of each bread slice with 1½ tablespoons mayonnaise. Arrange tomato slices on mayo side of one bread slice: top with other bread slice, mayo slice down. Enjoy the messy, juicy goodness immediately!!

< Back Zinnias: Vibrant Accents to a Northern Garden You know that zinnias provide a beautiful flourish to the summer garden. The varieties and colors are endless and can be enjoyed from late Spring into the Fall. But did you know that growing Zinnias from seed is both easy and rewarding? Read this article to learn why you might want to grow your own zinnias from seed this year. Jim Lakin, M.D., Master Gardener Not every seed is created equal. Trying to get some of the native perennials to germinate seems to require an Act of Congress. And they’re gridlocked! Not so with the humble but glorious zinnia. In my book, zinnias are some of the most overlooked yet rewarding annuals a Minnesotan could hope for. Although originating in Mexico and the Southwestern U.S., varieties have been developed all over the world. Yet they all still retain their love of warmth and sunlight, a commodity sometimes in short supply up here. Fear not! Simply sew zinnia seeds after the last hard frost and bide your time. As things warm up the seedlings will take care of the rest, producing blooms from late spring, far into the fall. If you have a warm sunny spot inside, you might even consider starting some seeds four to six weeks before the last frost. Unlike some more persnickety plants, zinnias germinate readily. You can set them out in the garden when they get two to four inches tall and enjoy weeks of blooms before the seeds you sewed get in gear. There are many varieties of zinnias ranging in height from 6 inches to 4 feet. I like the older, smaller blooms. They are hardy, fast growing, and tough plants. As I said, they do need full sun and warmth, but ask little else. One fertilization a season usually suffices. They are quite disease resistant. Powdery mildew seems to be the only common malady. It doesn’t look very attractive, but the plants usually survive. To keep them happy and mildew free, select a well-drained location for planting. Zinnias don’t like their feet wet. Mixed zinnias in full summer bloom If you find a variety you really like, consider collecting seeds in the late fall. Just cut off the spent flowers, shake out the seeds onto a sheet of paper, slip them into an envelope and store in the fridge until early next spring to start indoors or sew in the garden a bit later. Either way you will have bold, bright colors to cheer you through the gardening season!

< Back Deciphering Seed Catalogs Seed catalogs start coming in January or February - a good time to start dreaming of your next garden! But there is so much information packed into a seed catalog it can be hard to interpret the abbreviations and array of plant varieties. This article will help you to decipher your seed catalogs so that you can choose the best plants for your garden. Marjorie Blare, Master Gardener Seed catalogs start coming in January or February - a good time to start dreaming of your next garden! There is so much information packed into a seed catalog! Most people have no problem with the catalogs’ rapturous descriptions of flowers or produce. After all, the catalogs are full of (probably 'enhanced') photos! More bewildering are the icons next to the photos. A good catalog has a key that explains what each icon means. They might have a drawing of a circle that is half dark and half light. They should also explain how many hours of direct sun that icon indicates, perhaps 4-6 hours. The key may be at the front of the catalog, or at the bottom of the page. Plant descriptions can have letters next to them. For instance, tomatoes may have the letters VFM. This means that variety has resistance to verticillium, fusarium wilt and nematodes. Without those letters, describing a plant as “disease resistant” is useless. Tomatoes will be listed as determinate (bush) or indeterminate (vining). You may find the letters OP (open pollinated), F1 (first generation hybrid) or X (a 'cross') in its name. F2 is a hybrid that can only be propagated vegetatively. These letters are important if you wish to save seeds. The OP seeds will breed true, but not the others. Flowers will have 'days to bloom' and/or 'bloom season' in their description, and veggies will have days to maturity or harvest. Note: 'days to harvest' for plants started indoors count from the day it is planted out. These numbers are based on the seed company's test gardens; choosing northern-grown seeds or plants, will make those numbers more accurate in Dakota County. The description or icon will tell you when to direct-sow the seeds or when to start them under lights. The latter requires you to know the average date of the last or first frost. Dakota County's dates are May 8th and October 10th respectively. It will tell you how many seeds are in a package, how far apart to plant, soil conditions (alkaline or acidic, clay, sandy, loamy) and watering requirements. Left-over seeds can be donated to a seed library, shared with friends or saved in a dry jar in the refrigerator. There will be shipping charges on the packages of seeds, so try to order all at once, or with friends, or with a heavier item. If you are getting perennials, make sure to choose plants that will grow in our U.S. Department of Agriculture (USDA) zone. Dakota County is zone 4. Some catalogs “stretch” the range of zones, so try to compare what different catalogs claim about the same plant or seed. Some catalogs include a USDA map and perhaps a table of temperature ranges. The catalog should list the scientific name of the plant, because common names are frequently shared by several unrelated plants. On-line catalogs will have simplified descriptions, but also have links to click to open up more information. They may also have customer reviews which are very helpful!

< Back How to Share Your Plants Safely Sharing plants from our gardens is a common and gratifying practice among gardeners. But in these times, we must know how to share plants safely. Safe from what? Jumping worms have become a significant and difficult problem for Minnesota gardens. This particular type of worm has the ability to ravage your garden soil and weaken or kill your plants. This article will help you learn more about this pest and show you how you can still share your plants safe from the spread of jumping worms. Mary Gadek, Master Gardener The Dakota County Master Gardener Plant Sale is scheduled soon. As we plan to share the lovely garden flowers abound in Dakota County, we will be mindfully bare rooting the plants before donating to the sale . If you are planning to share plants from your garden with others this summer, bare rooting them is the safe way to do it. Why bare root?! The goal of bare rooting plants is to prevent the spread of jumping worms, which are an invasive species of worms in the United States. The worms can produce significant destruction in your garden by severely impacting the soil structure of your garden and reducing or destroying plant growth. Read this article from the University of Minnesota Extension to learn more about jumping worms in Minnesota. Prevention is key to limiting the spread of invasive jumping worms. Since soil, plant roots and mulch are the common materials most likely to spread the jumping worms, you can play an integral role in minimizing jumping worm issues. Note that in the spring, jumping worms are either cocoons or juveniles. The cocoons are the size and color of soil aggregates so they are difficult to see. Juvenile jumping worms may look like other juvenile earthworms at this point, without the telltale cream color collar, so they are hard to find or identify. These worms and juvenile worms can easily hide inside the roots of your plant. You can still share your plants and dramatically reduce the spread of jumping worms by taking steps to “bare root” your plants. The remainder of this article will provide step-by-step instructions about how to do so. How to Bare Root Your Plants Before sharing your beautiful garden plants, please take the following steps to bare root your donations. SUPPLIES: Drop cloth for work area; your plant; deep tray or wash tub; chopsticks or bamboo skewer; 4-5 five gallon buckets, with all but one half full of water; sheets of newspaper; paper towel; sterile soil; twine; label; 5 gallon elastic-top paint strainer and a gallon sized plastic bag. DIRECTIONS : 1. Prepare the work area with a dropcloth. Take the plant out of its pot over the deep tray/washtub. Using the chopsticks/skewer or your hands, completely remove all the dirt directly into the tray. 2. Rinse the roots in 2-3 of the water buckets until clean. 3. Examine the roots to ensure no dirt or potential jumping worm cocoons remain. 4. Position one sheet of newspaper into a diamond shape. Set a paper towel in the middle of the newspaper. 5. Lay the plant on the paper towel. Sprinkle sterile soil on the roots. 6. Wrap the bottom of the newspaper up on the roots and dirt. Fold in both sides of the newspaper over the roots. Tie the packet with twine. 7. Attach a label with the plant’s name to the twine. Write the plant’s name on the newspaper, too. 8. Put the tied packet into a bucket of clean water (ie., a bucket of water not used to rinse the roots) to hydrate it initially, removing it after soaked. Water the packet daily. 9. Return the dirt from the washtub to the old plant pot. Put the dirt back where it came from. 10. Pull the elastic paint strainer over the empty bucket. Dump everything collected in the other 5 gallon buckets (that you used to rinse off the plant’s dirt) into the empty bucket. Remove the strainer and the strained material into a gallon sized plastic bag. Seal the bag and discard it in the trash. Tip the bucket to empty the water into the area where the plant originated. Clean the dropcloth to prevent inadvertent spread of the worms/cocoons. NOTE : Since no earthworms are native to Minnesota, drop any worms found while bare rooting into a plastic bag, seal it and put it in the trash. Do not compost. With a little practice, you’ll get the hang of bare rooting. A practice well worth it to keep your garden healthy.

< Back Planting Seeds with Children Kristen Beardsley Schoenherr and Mary Gadek, Master Gardeners Kids love to plant seeds, and it’s a great way to show them the joys of gardening. Now’s the time to get seeds started for indoor and outdoor growing. Kids love to plant seeds, and it’s a great way to show them the joys of gardening. Now’s the time to get seeds started for indoor and outdoor growing. Explore these educational resources for you and your family. WATCH, READ and DO! WATCH this how-to video ! Read The Tiny Seed by Eric Carle (Ages 3-8 ) A simple description of a flowering plant's life cycle through the seasons. Check it out at Dakota County Library or Buy online Plant a Little Seed by Bonnie Christensen (Ages 4-7): Children plant a seed, care for their flowers and vegetables during the growing season, and enjoy the harvest. Check it out at Dakota County Library or Buy online DO activities for different age groups This month we have two suggested project for you to try with your children: 1. Seed Starting with Young Children MATERIALS Child sized apron (optional) Mat/waterproof cloth to work on (optional) Seed starting soil in an airtight container Child sized trowel or spoon Plant pots (cam reuse old yogurt or egg containers, clear container to see roots, something decorated, etc.) Seeds displayed based on the age and abilities of your child, with or without seed packets and plant labels (for a young toddler maybe put out many types of seeds so they can see the variety, for an older toddler maybe put out one type of seed with the seed packet and labels, and older child can write their own labels and can be given more seed choices. Little pitcher/watering can/spray bottle Cloth for cleanup A warm lit place to put planted pots Tray to help carry materials, materials should be arranged from left to right in order of use Place to work, can be a little table, counter with a stool for child, kitchen table, or the floor. PRESENTATION OF ACTIVITY Invite child when they are well rested and feeling good. Show them where the materials are located and invite them to help carry the materials to where you will work. (If you are right-handed, sit to your child’s right, opposite for left handed. This will allow the child to see what your hands are doing.) Name each material as you take it off the tray (this is a great embedded language/vocabulary opportunity) Say, “I will plant one seed and then you can have a turn.” “Watch.” (This draws their attention to your hands.) Open container with soil, show the child how to carefully scoop the soil and place it in the pot. Close the container. Introduce seeds. “I’m going make a little hole for the seed.” Show how to make a little hole, put a seed in the hole and cover it with soil. “We only need one seed.” (they may plant more, and that’s okay) If you are using labels, show how to label the plant or how the child can create their own label. “Now we need to get some water.” Get water in the pitcher or watering can and pour on soil or show how to squirt spray bottle. Show child where they can put their planted seed. Clean up any spills as you go. “I see there is a little spill, I will clean it up.” “Now you can plant as many seeds as you like, when you are finished, I’ll help you clean up.” Offering multiple pots helps to encourage repetition. Empty pots can be kept in a different spot, instead of on the tray if that is easier. THINGS TO CONSIDER WHEN PRESENTING Young children are creatures of process not product. They benefit from simply doing the activity or even a part of the activity as opposed to the finished product. These seeds may or may not grow into great seedlings that can be transplanted into the garden, and that is okay. Limit language and distractions during the presentation and while the child is working. If you want to point out something additional or add more language or sensorial opportunities, try these at a different time. When you show your child how to plant seeds for the first time ever or the season you want them to focus on the activity and your hands so that they can be most successful. SENSORIAL OPPORTUNITIES AND EXTENSIONS It can be fascinating for young children to shake the seed packets and hear the noise that different seeds make. They can notice how the sound changes with seed shape. Collect a variety of seed packets for your child to shake. Make sure to pick some large seeds, such as peas or squash, and some small seeds such as lettuce or carrots, so that the child can hear the different sounds while shaking the packets. This activity will help the child develop their fine motor skills while learning about music and sounds! Children might love feeling the soil and become entranced with using their hands. Others may hate the feel of the soil and don’t want to touch it. When you offer the child to have a turn, it is a great opportunity to sit back and observe how your child proceeds. They do not have to repeat exactly how you modeled. LANGUAGE EXTENSIONS At a different time, invite your child to observe different kinds of seeds with you, notice and discuss similarities and differences. On a plate or tray lay out small piles of various seeds. Ask the toddler to describe the seeds. Questions you could ask: Is the seed round or flat? What color is the seed? Which seed is the largest? Which seed is the smallest? Which seeds look similar to another kind of seed? Let the child pick up the seeds to explore them. This activity will help the child develop their descriptive vocabulary and fine motor skills while learning about various seeds.Three period language lesson: Choose three types of seeds that are quite different. Tell the child the name of each seed, “This is a sunflower seed, this is a bean seed, and this is a pumpkin seed.” Ask the child fun questions to reinforce names of each seed. “Where is the pumpkin seed? Put the pumpkin seed next to the bean seed. Give the sunflower seed to your brother.” Test knowledge by asking, “Which seed is this? Which seed is this?” If your child answers incorrectly no need to correct them, simply say which it is, “That’s the bean seed.” This can be done in a group or with an individual child. MODIFICATIONS This activity is very easy to modify. Seeds and planting containers can be switched regularly to meet your family’s gardening needs and preferences.This activity is intended for one child to do at a time (young children love working alone and can concentrate best when alone), but we easily used the same materials and a similar process to include our child in our family’s group seed planting. If you have multiple children, you may need multiple trowels so they each could fill pots at the same time. Or one child could fill a pot, one plant a seed, and an older child could write a label. 2. GRASS HEAD PROJECT - WATCHING GRASS GROW CAN BE FUN! PURPOSE Introduction to plant biology to observe seeds transforming into a plant and to learn how to take care of a plant. EQUIPMENT Clear container with wide opening and its cap (plastic cup or item recycled from your household) Items to create a face on the container (permanent markers, puffy paint, colorful seeds, pipe cleaners, goggly eyes, stickers, etc.) Potting soil Fast growing seeds, like grass seed-bag of lawn patch kit or cat grass Optional- glue; scissors INSTRUCTIONS Punch a hole in the bottom of the container for drainage.Decorate a clear container to make a face on one side.Fill container ¾ full of soil; sprinkle seeds on top of soil; top with additional soil. Put the container cap or a shallow dish under the container.Set the container near a light source. Water (daily) so soil doesn’t dry out; since the container is clear, you can see if the soil is adequately saturated (not too little or too much). Watch the seeds grow! LEARNING POSSIBILITIES Explain what a plant needs to grow: soil, light and water.Growth cycle: Notice how the seeds are changing under the soil and then how the plant grows above the soil. Activities:Measure and record growth in a written and/or photographic journal.Predict how long it will take for grass to grow to a certain height.Give the grass a haircut with scissors and watch regrowth happen.Repeat A and/or B.

< Back Pet-Safe Plant Choices Sarah Heidtke, Master Gardener There are a lot of us in Dakota County and beyond who love both plants and our pets. Not all plants are compatible with the dogs and cats who live with us. Read on to find out about safer plant choices to make for our furry family members - and a few plants to keep away! I adopt new houseplants every year around January. Some fresh green helps me through the winter months - whether I’m expanding my collection or filling in for some plants that weren’t a good match for my environment (Master Gardeners get brown plants sometimes, too!) We have beloved dogs and cats in our family, so we want to make sure any plants we have within reach are going to be safe for our pets. If you are gifting houseplants, it is a good idea to keep in mind all of the household residents who can access the plants! I would recommend leaving any plant identification instructions and labels with the plant. This extra care also includes floral bouquets, so watch for danger there (think lilies, tulips and gladiola as examples). Today, I’m offering some houseplant options that are safer for dogs and cats: 1. Hoya Hearts (Hoya kerrii), just in time for Valentines Day! 2. Boston Fern - Many true ferns are nontoxic. This plant loves humidity and is a great option in a bathroom with a shower. Be careful, though, of plants such as “Asparagus Ferns” (Asparagus densiflorus cv sprengeri), which are not true ferns. These plants are actually related to the lily family - and are not safe for pets! 3. Rubber Plant (Peperomia) 4. Money Tree (Pachira aquatica) 5. African Violets (Saintpaulia spp.) 6. Gerbera Daisy (Gerbera jamesonii) 7. Bamboo or Parlor Palm (Chamaedorea elegans) - but be careful of Sago Palms (Cycas revoluta), these are very toxic to pets! 8. Moth Orchid (Phalaenopsis sp.) 9. Holiday cactus (Schlumbergera) make great year-round houseplants 10. Many other succulents, such as Echeveria and Burro’s Tail are safe options as well. Check out this article from the Minnesota State Horticultural Society for more helpful information: A good general rule with all plants is to know your pets and double check plant labels . I have senior dogs that are more inclined to reach for the peanut butter spoon than any old plant, so I feel comfortable keeping riskier plants elevated and check for fallen leaves regularly. Some common plants in my home that are toxic to dogs and cats are Aloe, Amaryllis, Dieffenbachia, English Ivy, Eucalyptus and Philodendron. If you have a new puppy or kitten that can get to and munch plants in the house, you’ll need to adjust accordingly and stick to safer plants. Most plants can cause upset tummies if ingested or chewed on, but the above options will help avoid some more serious consequences. You can search toxicity by plant on the ASPCA’s website here . If your fur-baby has gotten into something they shouldn’t have, time matters. Here are a few resources if you are concerned your pet has ingested, touched, or inhaled poisonous substances - plants or otherwise: The University of Minnesota School of Veterinary Medicine recommends Pet Poison Helpline. - For general information or just checking, their website has tons of useful information including Top Ten Plants Poisonous to Pets . - For emergency help, you can call them at 855-764-7661 or email at info@petpoinhelpline.com ( please note there is an $85 incident fee applicable in this case ) ASPCA® (American Society for the Prevention of Cruelty to Animals®) also has a poison control line (888) 426-4435 and some additional resources on their animal poison control website . Check out this website from beChewy and Monrovia for some great outdoor container “recipes” filled with pet-safe plants. They also have great tips on gardening around pets. You and your pets will have a shopping list ready when the weather warms up in the spring. Have fun enjoying your plants and healthy pets!

< Back Grow Pear Trees Successfully In Your Back Yard Marjory Blare, Dakota County Master Gardener Pear trees can be just as easy if not easier to grow than apples! Find out how in this article. I am sorry to report that Partridges are a mostly ground-dwelling bird, so you’ll likely not see any in your trees. www.allaboutbirds.org Do partridges occur in pear trees? Around this time of year we do receive a spike in sightings of partridges in pear trees, although curiously there never seems to be more than one individual reported per pear tree. Both partridges and pear trees are Old World species that have been introduced into North America, which means that th Pears originated in central Asia and have spread around the world. They have been hybridized to survive in hardiness zones 4-8, although some can tolerate zone 3. The blossoms will die if there is a spring freeze of 24F°. Pear trees can be up to 40’ tall, but there are some semi-dwarfing rootstocks that will result in a 15-20’ tree. Most pears fruit on spurs. Spurs form on wood that is two years or older. Fruit buds are fat and furry, leaf buds are slender and smooth. Fruiting spur Pear trees will do reasonably well in a wide range of soil types, although they don’t like wet feet. Pear trees require full sunlight all day long. You will need two varieties of pears for optimum pollination. “Summer Crisp” and “Patton” work well together; both have a certain amount of disease resistance and are hardy here. Fire-blight is the most serious disease and should be pruned out to a minimum of 6” below the disease. The pests that can attack pear trees are rabbits and voles (winter bark damage), deer (browsing and antler rubbing). Japanese beetles feed on pear leaves, but not to damaging levels. This link includes planting instructions: https://extension.umn.edu/fruit/growing-pears Pruning is just cuts and consequences. A plant can be pruned at any time of year – you’ll just get different consequences. Begin pruning a pear tree in late winter before the buds begin to swell. Earlier pruning encourages water sprouts and suckering in spring and summer and also increases the chances of winter injury to the pruning sites. Summer pruning of fruit trees controls excess growth on a tree by removing energy-wasting water sprouts. Summer is also a good time to remove leafy upper branches that excessively shade fruit on lower branches. https://extension.psu.edu/pruning-apples-and-pears-in-home-fruit-plantings A few weeks after pruning, new growth will be vigorous and can have very narrow crotch angles. To prevent this, you need to force the new shoots to a more horizontal growth pattern. If a limb is not spread, as in the picture to the left, a bark inclusion can develop, i.e. the bark of the trunk and the branch grow together. This weakens the branch and can be an entry point for disease. Weak branch angle with bark inclusion A wide-angled branch, results in a stronger branch that can carry future heavy crops. Limb spreaders improve the tree shape and form strong crotch angles. Young branches can be clothes pinned, tied or weighted down. Spreaders can be either short pieces of wood with sharpened nails driven into each end or sharpened metal rods. Spreaders should remain in place until the branch "stiffens up" (1-2 years). Strong branch angle The summer after the first winter pruning, remove any water sprouts that grow on a heavily pruned tree. Water sprouts grow around pruning cuts. If you use pruning shears, you never quite get the entire shoot. Instead, pull the shoots off the trunk and major side branches, shoots can be pulled off safely throughout the season as long as their bases remain tender and green. Heading cuts shorten a limb or shoot. This removes the terminal bud that normally stops shoot development from buds closer to the trunk. This also causes several shoots to develop near the cut, which results in a thicker, denser canopy and reduced light levels. A thinning cut removes an entire shoot or branch back to its point of origin. Thinning cuts do not induce excessive vigorous regrowth and will open the tree to allow more sun inside the interior. Harvest and Storage Pears should be harvested while they are still firm and green. Some pears rot from the inside out, if they ripen on the tree. For best results, find out the approximate maturity time for the cultivar, watch for a slight color change from a darker to a lighter shade of green, and check fruit size. Store mature pears in the refrigerator, then ripen at room temperature for up to a week before eating or canning. Pears bruise easily, so, handle carefully when picking and storing! https://extension.unh.edu/resource/growing-fruits-growing-pears-home-orchard-fact-sheet Happy growing and check out the many wonderful pear recipes found on the internet!

< Back Butterfly Milkweed (Asclepias tuberosa): Best Friend to Many Pollinators Jim Lakin MD, Master Gardener Watching Monarch Butterflies flit among the plants in our gardens is among the simple joys of summer in Minnesota. But, as we know, the population of this beautiful butterfly is diminishing. One of the likely causes is loss of habitat – not enough available plants that the larvae and butterfly need for fuel. As this article explains, the Butterfly Milkweed is a native plant that Monarchs favor. For that reason and more, you may want to add this plant to your garden next year. If you are like me, one of the great sights of summer is a flock of Monarch Butterflies dancing about the garden. Their numbers have been diminishing over the past few years. Many entomologists feel that this is due to loss of habitat, as we pave over and grass over many vital native ecosystems that traditionally have supported them on their long migration from Central Mexico. One solution, with a good bit of data to support it, is to create a string of mini-environments of native plants as “refueling stations” for the Monarchs on their journey. One favored source of “fuel” (nectar) is the Butterfly Milkweed. Asclepias tuberosa is a favorite of a number of pollinators. It, along with the other milkweeds, forms an important link in the native ecology of the Midwest, being found from the Eastern Seaboard through to the Rockies. In addition to its vital ecological role, Butterfly Milkweed is a gorgeous yet hardy, low-maintenance plant that will be an attractive addition to your garden. Butterfly Milkweed blooms with a bright orange to reddish yellow flower from late spring to late summer. It has narrow green leaves which serve as an important source of food for Monarch butterfly larvae. It is hardy up through Zone 3, so you North Shore folks are in luck! The plant grows to two to three feet, so it is best placed to the back of your beds. It can be started from either seeds of cuttings. We have a patch in our front which has gradually spread from spontaneous seeding. If you are trying to germinate from seed, remember to put the seeds in a damp cool environment, like a moistened paper towel in a baggie in the fridge, for 4 to 6 weeks before planting. Alternately you can sow the seeds outdoors in the late fall, covering with about ¼ inch of soil. You may not see blooming the first year, however. Photo Credits: www.flickr.com (1) , usda.gov (2)
