< 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 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. Check out our Master Gardener videos on growing Delicata Squash: “How, When’s, Where’s,” “Delicata Squash Borer Protection,” “Delicata Squash Borer,” and “ Delicata Squash Harvest.” Sources: https://extension.umn.edu/news/master-gardeners-are-busy-during-winter https://www.countryliving.com/food-drinks/g4686/delicata-squash/ https://extension.umn.edu/vegetables/pumpkins-and-winter-squash#choosing-pumpkin-and-winter-squash-varieties-235460 https://en.wikipedia.org/wiki/Delicata_squash Photo Credit: Gurney's Seed and Nursery,creative Commons Licenses (1) & Centerstagewellness.com , Flickr Pro (2)

< Back Identifying and Attracting Beneficial Insects Joanna Kapke, Master Gardener Now that the plants in our gardens are starting to bloom, we are also seeing insects on those plants. Some of those insects are certainly pests but others are actually beneficial. We know how pollinators are beneficial insects - many of the foods we enjoy rely on pollinators for fruit and seed development. But how do we identify other insects that are beneficial to our gardens and landscapes in other ways? Read this article to find out! Now that the plants in our gardens are starting to bloom, we are also seeing insects on those plants. Some of those insects are certainly pests but others are actually beneficial. We know how pollinators are beneficial insects - many of the foods we enjoy rely on pollinators for fruit and seed development. But how do we identify other insects that are beneficial to our gardens and landscapes in other ways. Beneficial insects (at various stages in their life cycle and using multiple methods) can help manage the populations of insect pests like aphids. Some examples of beneficial insects include ground beetles, lady beetles, lacewings, syrphid flies and a variety of solitary and parasitoid wasps. Many of the recommendations for attracting pollinators to your garden—planting a variety of flowering plants, including native plants in your landscape or providing a water source/feature—are also true for encouraging beneficial insect visits. But beneficial insects need more than the aphids and larvae you want them to eliminate. They need pollen and nectar for energy and places to shelter and overwinter to encourage them to stay in your space. Here are several gardening strategies to attract and retain beneficial insects in your garden: Have an array of perennial and annual plants flowering consistently throughout the growing season. Leave some aphids on plants. Allow some plant litter to stay on the ground over winter. Limit or eliminate the use of pesticides. Certain plants also attract beneficial insects. In many cases, smaller flowers will attract smaller insects like syrphid flies. Some flowers commonly listed as attracting beneficial insects that do well in Minnesota gardens are: yarrow, dill, alyssum, cosmos, gem marigolds, clover, cinquefoils, fennel, lemon balm and milkweeds. For more ideas, check the internet for lists of plants that attract beneficial insects. Before adding any new plants to your yard in order to attract beneficial insects, check your local DNR list of invasive species to ensure there isn’t crossover. For example, common tansy and Queen Anne’s Lace are often listed as plants that will attract beneficial insects. But in Minnesota, both are considered noxious weeds and it is illegal to import, sell or transport them within the state. You can purchase many species of beneficial insects online. Before doing so, take a few things into consideration: Can you follow the release instructions exactly? Will you need to repeat the process? Insects often…fly away. Is the pest you are hoping to eliminate a serious problem? It can often be more sustainable to make your landscape more welcoming to beneficial insects than trying to repeatedly introduce species that have been ordered from other sources. For more information on specific beneficial insects, their life cycle and what they can do for your garden visit this U of MN Extension site. Take some time to learn more about the insects that you want to attract to your garden. Your plants will appreciate it! Photo Credit: Joanna Kapke (1,2,3)

< Back Best Time to Prune Trees Faith Appelquist, Master Gardener Although trees are quite resilient and may be pruned anytime, there are both practical as well as biological reasons to prune or not prune during certain times of the year. Although trees are quite resilient and may be pruned anytime, there are both practical as well as biological reasons to prune or not prune during certain times of the year. If it is between opening up a wound to heat or opening to the cold, opening the wound to the cold is best. Optimally, the perfect window would be past February and into March. The chance of frostbite on the sensitive cambium is less, and the sap is not rising. When certain species are trimmed during the growing season, such as American Elms or Oaks, pheromones (scents) are given off at the wound, attracting insects that can carry fungus on their bodies that can infect these trees. These trees are best pruned in the fall or early spring. Deadwood should be pruned anytime because it is a health and safety issue. Deadwood is food for decay organisms and the quicker it is removed from a tree the sooner it can start closing the wound and preventing the spread of decay. If the tree was planted for its spring flowers, such as magnolia, dogwood, crabapple, you will want to wait until after it has flowered to prune. Otherwise you prune flower buds off and reduce the abundance of flowers that spring. For certain species such as maples and birches, I would trim these in the summer to minimize sap oozing or ‘bleeding’. Pruning during full leaf is fine, but dormant season is probably still best for tree health.

< Back Managing Salt Damage on Plants B.J. Hansell, Dakota County Master Gardener Minnesota winters inevitably bring snow and ice on our driveways and sidewalks. Various deicer products are often used to manage these winter hazards. But many Minnesota plants are sensitive the chemicals that are in the deicers. This article will help you to know which plants are susceptible to salt damage and which plants can resist salt damage. Winters in Dakota County can be freezing cold, snowy, and windy. These conditions require sidewalk shoveling, driveway snow-blowing, manual ice scraping and street plowing up to and including applications of deicer products. Your d iligent clearing of snow and ice may minimize the amount of deicer spread across sidewalks, and driveways during the course of winter. Remember also, that as the ice and snow melts, the salts will run-off into the garden and impact garden plants roots. Many Minnesota plants are sensitive to road salt, which can cause dehydration, nutrient deficiencies, and eventual death due to both salt spray on foliage and salt accumulation in the soil. Evergreens are particularly vulnerable. The composition of deicer products varies depending upon requirements of the area. The primary difference is that "road salt" typically refers to raw, inexpensive rock salt for large-scale use, think streets and highways. While "sidewalk salt" (or "ice melt") often includes blends of different chemicals such as calcium chloride or magnesium chloride which are more effective in colder temperatures and can be less damaging to surfaces and plants. You can minimize the negative effects of deicer products on the plants in your garden by understanding which plants are better able to tolerate the chemicals. Choice of plant type and placement augments the plant’s innate ability to tolerate deicers salts. Here is information about plants that are and are not tolerant to deicers. Native Minnesota trees and shrubs that are sensitive to road salt include: Maples (Red maple, Silver maple, Sugar maple); Dogwoods (Grey dogwood, Red-osier dogwood, Red twig dogwood); Basswood (American basswood, Littleleaf linden); Pines (Eastern white pine, Red pine, Scots pine); and Firs (Balsam fir, Concolor fir). salt damaged evergreen Meanwhile, other Minnesota plants, including trees, shrubs, and perennials, are tolerant of road salt and are excellent choices for landscaping near roads, driveways, and sidewalks. Deciduous plants are generally more salt-tolerant than evergreens as they shed their leaves annually. These include trees such as: Oaks (Bur, Northern Red, and Swamp White); Hackberry; Honey Locust; Kentucky Coffee tree; River Birch; Serviceberry and Eastern red cedar. Along with shrubs : Sumacs (Staghorn & Smooth); Chokeberry; Winterberry; Lilacs; Viburnums ( Viburnum spp. ); Junipers ( Juniperus spp. ); Potentilla; and Rose ( Rosa rugosa ). Black Chokeberry Additionally, the following grasses, perennials and wildflowers are effective at handling both salt spray and soil accumulation and are excellent for boulevard gardens. Grasses : Little Bluestem; Big Bluestem; Switchgrass; Prairie Dropseed; Perennials and Wildflowers: Black-Eyed Susan; Purple Coneflower; Goldenrod; Asters; Butterfly Milkweed; Catmint; Sedums; Daylilies; and Yarrow. Common Milkweed For specific recommendations on seed mixes for different applications, the Minnesota Stormwater Manual provides detailed guidance.

< Back Indulging in the World of Mulching Spring has sprung in Minnesota! Are you thinking about putting mulch in your garden or wondering if you should? Resolve to learn more about mulching in your landscape beds this year. As you wander around your gardens and at the local landscape and garden supply stores, you may wonder which type of mulch to use, where to apply it and what time of year is appropriate for such mulch. Read on to find out the answers to these mulching questions. Mary Gadek, Dakota County Master Gardener CATEGORIES OF MULCH ORGANIC Organic mulches are natural materials that decompose over time, adding nutrients and organic matter to the soil and beneficial microorganisms that inhibit plant diseases. The increased amounts of organic matter will improve soil drainage and moisture retention, reduce soil compaction, and attract earthworms. Because organic mulches decompose, they need to be replaced. Depending on the type of mulch used, replacement intervals vary from one to four years. Bark: Available in bags or bulk, bark mulch comes in various particle sizes, ranging from fine to large chunks with some decorative colored/dyed options. This attractive mulch is weed-free and decomposes slowly, with cedar and cypress being the slowest. Use bark mulches around trees, shrubs, and roses, as well as in perennial beds. Photo by Mary Gadek daffodils surrounded by wood mulch Wood Chips: Wood chips from local arborists, municipal facilities, or waste sites are produced by chipping or shredding tree and shrub trimmings. Shredded mulch is less likely to blow or wash away than chips. Wood chips are best used in most landscape plantings, including around trees, shrubs, and roses, and in perennial beds. Be aware: Some commercially available wood chips are made by shredding or chipping lumber or pallets. They are an inferior product that breaks down quickly and may contain chemicals. These products are sometimes dyed to mask their origin. Check labels or with your garden center to avoid such products. Wood chips are best used in landscape plantings, such as around trees, shrubs, and roses, and in perennial beds. Pine Needles: Pine needle mulch, or pine straw, is light, airy, slow to decompose, and attractive. It lasts several years and can be easily removed, if necessary. Pine needles are slightly acidic, although their effect on soil pH is relatively minor. Use pine needles in the landscape, especially around trees and shrubs, and perennials. Available at local garden centers or under the pine tree in your yard. Photo by Mary Gadek straw mulch in garden Cocoa Beans Shells: Cocoa bean shells or cocoa hulls are a by-product of chocolate production. They are light, easy to handle, and have an attractive brown color with a pleasant aroma. This mulch is more expensive than most, but a depth of 1 to 2 inches is sufficient. Best to use for annuals, large containers, perennials, vegetable gardens, roses and sensory gardens. They typically last about one growing season. WARNING: Dog owners should monitor their dogs closely, as dogs may develop signs of chocolate poisoning if they ingest it. Straw: Wheat, oat, or soybean straw, free of seeds , makes effective short-term mulch for the vegetable garden and strawberry bed as well as overwintering insulation for cold-tender plants. Avoid using it around trees and shrubs as it may provide a winter habitat for mice and other rodents. Sawdust : Sawdust is easy to apply, weed-free, and decomposes slowly. Apply sawdust in vegetable gardens, perennial plantings, or around trees and shrubs. Use saw dust that either has been composted or aged for a year, or a thin layer (1 inch or less) of fresh saw dust, ensuring it doesn't crust over, reducing water infiltration. Watch for nitrogen deficiency (when your plants appear light green to yellow colors and slow growth) when using sawdust due to the high carbon to nitrogen ratio. Refrain from using sawdust from treated lumber. Leaves: Taken right from your own yard, s hred or compost leaves before using them as mulch to prevent matting, reduce their likelihood of blowing away, and speed up decomposition. Utilize for vegetable gardens, annual flower beds, raspberry plantings, and around perennials, trees, and shrubs. However, skip applying for winter mulch for strawberries and herbaceous perennials because they tend to mat down and smother plants. Grass Clippings: Grass clippings decompose quickly, making them ideal for vegetable gardens, annual flower beds or left (without clumps) on your lawn while cutting with an unbagged lawnmower. Let lawn clippings dry before applying to gardens, as fresh clippings may form a dense mat or produce an odor. Avoid using clippings treated with broadleaf herbicide until after two or three mowings. Clippings from weed-infested lawns will contain weed seeds. Newspaper and Cardboard: newspaper and cardboard can be used as mulch (but is often then covered with wood mulch or compost), in vegetable gardens, garden pathways, and around trees and shrubs. Shredded newspapers or whole sheets can be used as mulch. Most newspapers use organic inks, so there is no worry about lead contamination. Avoid waxed cardboard and glossy paper, such as magazine pages. Remove tape and staples from boxes. This link provides additional instructions on how to implement this mulch. Compost: Compost, used alone or with other mulches, like shredded leaves or newspaper, helps improve soil structure, drainage, and fertility, but doesn't suppress weeds as well as other mulches. Compost can be used in nearly all garden settings, including perennial and annual beds, vegetable gardens, and around trees and shrubs. INORGANIC Photo by Mary Gadek Little Bluestem ornamental grass in rock mulch Inorganic mulches, include rock, gravel, rubber or plastic chips, plastic sheeting and landscape fabric . The benefits of inorganic mulches are: warming the soil in the spring or fall, suppressing weeds, limiting soil erosion on steep areas and preventing water infiltration where water is not wanted. However, inorganic mulches do not contribute to building soil fertility or composition, can overheat soil in the summer and often have organic material collected on top of it, leading to weed issues. Inorganic mulches usually are more tedious to install, may require additional irrigation and can be difficult to garden in, making planting, transplanting, and weeding challenging. Rubber or plastic chips eventually decompose, which can release chemical components that are not desirable for healthy soil. Organic mulches placed over landscape fabric can still get weeds and are more likely to wash away. WHEN TO APPLY MULCH In Minnesota, apply mulch i n early spring but wait until the ground warms and perennials emerge. Putting down a layer of mulch too early can further insulate the ground and slow plant emergence. In the fall, mulch can help protect newly planted perennials and other plants from harsh cold temperatures. For late-season applications, apply mulch after plants go dormant, but not too early, as it can delay dormancy and increase the risk of cold damage. BEWARE OF JUMPING WORMS Beware of jumping worms. Once you have chosen the type of mulch, keep reading to learn more about applying mulch to your garden as well as learning about invasive jumping worms which like to reside in mulch. Here is an article about mulch and jumping worms . For more jumping worm prevention, seek out garden centers that use the recommended best practices with their mulch. This is an article about best management practices. Mulching is often a good gardening practice but be mindful of the type of mulch your use and when to use it, in order to obtain the best result.

< Back Native Grasses for the Home Landscape Alyce Neperud, Dakota County Master Gardener Intern Native grasses, sedges and flowers can be stunning at any scale; from vast prairie to small garden. In addition to the visual appeal, they provide essential habitat for many native insects and birds. The vegetation of the mesic prairie ecosystems that once covered much of southern and western Minnesota included a profusion of flowering plants and grasses. These resilient plants adapted to survive cold winters, hot summers, flood and drought and are still excellent choices for most of Minnesota. This article shares the benefits of and considerations for making native grasses a part of your landscape. Benefits of Native Grasses Long lived perennials Drought tolerant and soil stabilizers; due to deep root systems Enhanced soil; fibrous roots slough off and break down into organic matter Food source for wildlife; butterflies, skippers, birds Shelter for native insects, including butterflies, moths and bees Structural; support other plants Competitive with weeds Characteristics of Native Grasses Primarily warm season grasses; grow in late spring and flower in the hot summer Either clump or running growth habit Wind pollinated; flowers are small, do not need to attract pollinators Arrangement and branching patterns of florets in the seedhead (aka grass inflorescence) determine how grasses are identified, named, and classified Clump (Blue Grama) Inflorescence (Side Oats Grama) Design considerations for your site: What are your goals? Are there any restrictions at your site? What are your water and soil conditions? Some grasses are more suited to sandy, dry, high ground while some tolerate more wet conditions. Do you prefer a formal or informal design? A formal garden generally takes more space so the plants can show their full shape and allow for layering of heights from front to back. Formal (Noerenberg Memorial Gardens) Informal (Mendota Heights Victoria Road) Do you prefer a mix of textures and shapes or a uniform look? The clump form grows outward slowly so is less aggressive and good for mixes while the running growth habit is beneficial if you want a single grass to fill in a space for a functional purpose, for example to stabilize a slope or create a mow-able lawn. Short to medium height grasses are suited to locations with limited space where visibility and minimal spreading is desirable. Preferred grasses are generally shorter, of clump form, include visual interest from color and/or interesting seed heads, and mix well with low growing prairie flowers. Prairie Dropseed is widely adapted to soils ranging from dry, sandy and rock outcrops to low, wet mesic habits. It is an elegant clump form, at 2-4’ height. The nativar “tara’ is shorter in form at 24-30”. See Reference #1 for more information. Prairie Dropseed - fine foliage and inflorescence in summer Little Bluestem is an iconic species of Minnesota prairies that prefers loose, well-drained soil. Grows in clump form, at 2-4’ high. Host plant for several native butterflies, skippers. Showy, bright red in fall with shiny silver seedheads. Little Bluestem - bluish foliage in summer Blue Grama does well in dry, sand to loam soil, not clay. Clump form at height of 12-30”.Horizontal seed heads provide interest. See Reference #1 for more information. Side Oats Grama is related, a bit taller at 2-3’ height, different inflorescence. Junegrass does well in very dry, sandy soils. It is short, compact and upright at 2-3’ and mixes well with low-growing prairie flowers. A cool season grass; grows in early spring, flowers and sets seed late spring or early summer. Tall Native Grasses are generally not recommended for home gardens as they may overtake flowers over time but they can be a feature, screen or backdrop for other plants where more space is available and/or height is desirable. Big Bluestem is found throughout Minnesota. Grows in sand, loam, clay soil. It is tall at 8’, upright and open. It tends to self-sow and dominate and is subject to ‘lodging’ (falling over). Several nativars with different growing habits and color are available. See Reference #1 for more information. Indian Grass is found throughout Minnesota and does well in dry to moist soils (sand, loam, clay) with a height of 5-7’. It is medium aggressive and tends to self sow. It has a good upright form with golden seedheads, looks great with little bluestem and medium to tall flowers at the back of a border or garden. If you haven’t considered native grasses for your landscape before, it may be time to reconsider. Native grasses can be a stunning addition to your pollinator friendly garden.

< Back Newby’s Vegetable Garden Marjorie Blare, Dakota County Master Gardener Spring is the time when many homeowner’s thoughts turn to gardening. New (or not so new) homeowners may want to start growing their own vegetables but are hesitant because they don’t know how to start. In this clever article, Master Gardener and experienced vegetable gardener, Margie Blare provides loads of good advice to the “Newby” gardener about how to start a vegetable garden. Read this article to start your vegetable gardening adventure. Once upon a time, there was a new gardener named Newby . One day Newby thought, “I would like to have a vegetable garden. Then I’d know where my food comes from and how it was grown. I wonder how I can do that?” With a flash of green, a figure appeared. “I can help!” exclaimed Greenthumb . Newby : “Hi Greenthumb , I have questions like, where should I plant my garden?” Greenthumb : “It depends! Choose a spot that gets 6-8 hours of full sun each day. To minimize weeding, consider a raised bed. Keep it simple, perhaps four 2 X 6s nailed together to make a 3 X 8 foot bed. At this width, you can easily reach across it. And, if that spot doesn’t work, you can move it next year.” Newby : “Can I just use the soil from my backyard?” Greenthumb : “It depends! You should get a soil test; watch this video to find out how. Soil tests let you know how much and what kind of fertilizer is needed. It will tell you how much organic matter is in your soil and will give recommendations for healthy plants, with no adverse effects on the environment. You can fill a raised bed with quality soil if your native soil is poor.” Newby : “So, I just put the seeds in the ground?” Greenthumb :” It depends! Some need to be started indoors and others do best when directly seeded.” Read the seed package learn what each type of seeds need. Newby : “When should I plant my garden?” Greenthumb : “It depends! Some crops are cool season; such as peas, spinach, lettuce, and many more. Others are warm season; such as cucumbers, beans, peppers, eggplant, tomatoes, squash and melons. You need to read the seed package. You can also check out this seed-starting calculator .” Newby : “My neighbor’s tomatoes got all black last year. How can I prevent that?” Greenthumb : “It depends!

What are they?” Greenthumb : “Plant hardiness zone maps show the temperatures of various places in the state and nation. It is necessary to know your zone when buying small fruits like strawberries and raspberries, and perennial vegetables such as rhubarb, horseradish and asparagus, to make sure the plants you buy can withstand the winters in our area. See the map above to find out your zone.” Newby : “Thanks Greenthumb!” Greenthumb : “Happy Gardening!” Photo Credits: Marjorie Blare (1,2,4), Hardiness Map (3)

This article explains how to engage in this fun and easy learning opportunity. Julie Henrichs Summer is upon us and what is better to grow with your child than flowers that are big, bright and beautiful. Sunflowers come in many varieties and heights and “Yes” they can be planted in containers too. Planting sunflower seeds with children is an incredible way to experience the entire life cycle of a plant. Sunflowers are ideal for planting with children because sunflower seeds are large in size for easy handling, tolerates dry or drought conditions and also is fairly low maintenance. Sunflowers are also “giving” plants - bees and bugs benefit from the flowers while birds eat the seeds produced. Let’s Get Planting Sunflower seeds come in all varieties, size and many colors ranging from yellow, orange, bronze, red, burgundy and even white with a variation of mixed petals. Allow your children to choose the type of sunflower to grow and then ask why they chose the one they did? Was it for the height, the extra fuzzy looking flower or simply the color? If you have height restrictions, refer to seed package for height and spacing guidelines. We think of sunflower seeds always being planted in the ground, but they can also be planted in containers. Choosing the best finished container is important and make sure to base the size of container by the plant height. Items Needed: Appropriately sized planting container (base size on final height of plant) with good drainage Sunflower Seeds Potting Soil Water in watering can or spray bottle Plant labels (optional) Gardening Gloves (optional) Let’s get started: Fill containers with potting soil, leaving dirt an inch away from the rim of the container. Once the container is filled, tap down lightly and add any potting soil as needed. Children can poke a small hole with their finger into the soil. Open the seed packet and have your child plant the seeds about 1-2 inches into the soil in the hole. Seeds can be spaced approximately 6-12 inches apart depending on the sunflower seed type. (refer to the back of the package for planting depth and spacing) Cover seeds and tamp down soil Water gently with a watering can being careful not to disrupt the newly planted seeds or spritz the soil with water making sure the soil is wet Set the newly planted containers in full sun. Continue to check the new plantings for watering needs at least once or twice a day. Once the seedlings have emerged, continue to check to make sure the soil remains moist, but not saturated. Seeds start to grow 1-1 ½ weeks after planting. As your sunflower begins to grow it may require staking to keep the plant upright, especially in strong winds. Sunflowers are unique in that they begin as a seed and also end as a seed. The sunflower plant produces a sunflower bloom/head. When the sunflower head starts to turn brown, the sunflowers can be cut off and either they can be left for birds and other insects or they can be dried and then used later. Sunflowers provide so many benefits – a fun and educational gardening experience, a beautiful display and food for birds and insects. Let’s get planting!
