< Back Put these insects under gardening law until you annihilate THEM! Marjorie Blare, Dakota County Master Gardener This is the time of year when bugs, not eliminated earlier in the year, try to take over your plants. Don’t get those creepy-crawly pests ruin your houseplants. Read this article to learn how to prevent getting those bugs and how to eliminate them if they manage to creep in. THEM : A HORROR HORDE OF CREEPY-CRAWLY PESTS CLAWING OUT OF THE SOIL AND FROM UNDERNEATH LEAVES! Kill one and two take its place! Steps you can take to reduce the chances of an infestation: Chose the right plant for the place it will live; take into consider light, temperature, soil/air humidity and air circulation. Before bringing them inside, inspect stems, tops and undersides of leaves (also the pots), for insects, webbing, holes and eggs. Things you can do to treat infestations: Use a forceful stream of water to dislodge insects. Physically remove pests with fingers or tweezers. Use yellow sticky traps to trap flying insects like whiteflies, fungus gnats or thrips. Small numbers of scale insects can be scraped off with a fingernail file or the like. Re-pot using new soil and sterilized pots, making sure to thoroughly wash off old soil. Prune if a pest issue is limited to a few leaves, stems or branches. Dispose of the entire plant if it’s heavily infested.

Apply chemicals outdoors whenever possible. Use a well-ventilated area to spray plants indoors. Enclose your plant in a plastic bag and seal shut. Cut a small hole and insert your spray nozzle. Spray your plant, especially under the leaves. Remove the nozzle and quickly cover the hole with duct tape. Keep it out of direct sun until dry. CAUTION: Mention of a pesticide or use of a pesticide label is for educational purposes only. Always follow the pesticide label directions attached to the pesticide container you are using. Be sure that the area you wish to treat is listed on the label of the pesticide you intend to use . Remember, the label is the law. Never use any pesticide on a plant that is moisture-stressed. Water the soil a day or two before applying pesticides. extension.umn.edu Managing insects on indoor plants With no natural enemies indoors, inspect your houseplants weekly for insect pests like mealybugs and scale.

< Back From Our House to Yours: Winter Sowing Native Plants for You! Marie Stolte, Dakota County Master Gardener Master Gardeners strive to be stewards of the environment. To that end, the Dakota County Master Gardener program seeks ways to support the efforts of community members to practice good gardening in their own yards. Planting native plants in your garden is one of those good gardening practices. To support that practice, the Master Gardeners’ Propagation Team grows native plants from local seeds that you can buy at our annual plant sale in May. In this article, learn how Master Gardeners collect, prepare and grow the native seeds. Master Gardeners using cleaning boards to clean native seeds Did you know that Dakota County Master Gardeners grow many of the native plants that we offer at our annual Plant Sale? At next year’s sale (on May 16, 2026, at the Western Service Center in Apple Valley from 8 until noon), you will find the 48 types of natives that our Propagation Team is growing this winter. There will also be shrubs, native grasses, and other plants that we obtain from local vendors. Our growing for the Plant Sale actually started in September and October, when we collected ripe native plant seeds from our own gardens. In November, we brought bags of dried seeds to the new Dakota County Parks’ greenhouse in Lebanon Hills Regional Park for cleaning. The Parks graciously allowed our approximately 15 volunteers to use their cleaning boards to crush seed capsules, scrub away the fuzz and chaff, and sieve the seeds. Master Gardeners sorting and cleaning seed It’s a time-consuming process, but important--removing the chaff means the seeds can get better soil contact at planting time. instrument to remove chaff from the seed; seeds in bottom cup are blown to the top of the tube where the lighter chaff is collected in side tubes. Seed sinks to bottom with less chaff Cleaned seeds that need no stratification were placed in envelopes, and are being kept in a cool, dark place until planting time in April. The rest of the seeds that required cold stratification (see Jessie Thompson’s article describing cold stratification in this January issue) for 10, 30, or 60 days went on to a second group of volunteers for winter sowing. Winter sowing is an easy process you can do yourself at home. All it takes is a plastic container that is at least two inches deep, damp potting soil to fill the container, seeds, water, a magic marker, and Mother Nature. Right after we cleaned the seeds in November, our volunteers punched holes in the tops and bottoms of containers that once held lettuce, strawberries, and grapes. Each container was filled with dampened potting soil. We planted the seeds at the proper planting depth. Finally, we labeled each container with the plant’s name and the date those seeds would complete the necessary cold stratification. Three Master Gardeners took all the containers home, watered them deeply, and set them alongside our homes. Mother Nature has taken it from there. The containers behind my garage were exposed to rain in the fall and are now covered with snow. Starting January 15, the first group of native plant seeds will complete cold stratification. More volunteers will take those containers, bring them inside their warm homes, and put them under grow lights. They will keep the seeds watered until they germinate. The little seedlings will keep growing in our homes until they go to the greenhouse for transplanting on April 1. From there, more Master Gardeners will tend to the seedlings and help them grow into healthy, mature plants suitable for our May Plant Sale. Look for more information about our Plant Sale this spring and consider bringing some of these native, home-grown plants for your yard. native Common Ironweed Photo Credits : MB Kufrin (1-3), www.flickr.com (4)
