Hello Gardeners
I know I just sent out an email, but I have 2 items of interest that are time sensitive.
I have placed various seed packets for seeds that need to be started early before the normal planting time in the seed drawers. This includes many annual and perennial seeds, vegetable seeds such as asparagus, celery, onion, rhubarb (locally harvested!), fennel, eggplant, cauliflower, collards, okra, and gourds and herb seeds of oregano, lemon balm, parsley, peppermint, sage, savory, rosemary, tarragon, thyme, basil, and sweet marjoram. (Dill and cilantro will come later as many seeds need packaging). Note that both peppers and tomatoes also need to be started early, but these seeds need packaging before I can put them in the seed drawers.
Depending on the seed variety, you may need to start these seeds anywhere from 14 weeks to 6 weeks before the average last frost date. The average last frost date in Zone 4, where we live, is around May 10th. The reason these plants need to have their seeds started early is that they need a longer growing season then our typical Minnesota growing season which is from the last spring frost to the first fall frost.
I’d love to have more locally harvested seeds from tomatoes! Locally grown seeds generally grow better than seeds grown in other locations.
5th Annual Pollinator Series Webinars
The second item of interest are some great free webinars by the University of Minnesota Extension. The 5th Annual Pollinator Series January 26-28th, 2026.
Curious about the best ways to support Minnesota’s native bees and strengthen pollinator habitat where you live? Interested in the newest research on bee health, habitat needs, and conservation strategies? This year’s three-part webinar series from University of Minnesota Extension brings together expert educators, researchers, and Master Gardeners to highlight keystone plants and “Soft Landings” designs, share the latest findings from the UMN Bee Lab, and showcase successful pollinator projects from across the state. Learn practical, science-based steps you can take to help pollinators thrive in any space—large or small. Join us January 26, 27, and 28 from 1:00–2:30 p.m. CST for this free webinar series. Pre-registration is required at z.umn.edu/BeeSeries to receive the webinar links.
Two wonderful speakers, Heather Holm and Dr. Elaine Evans as well as Master Gardeners will be the speakers for the series. I encourage you to register for the webinars.
To join for all or one of these webinars, please go to z.umn.edu/BeeSeries to register. You only need to register once to receive access to each topic. The Zoom link will be emailed to you immediately after you register. If you are unable to attend the live sessions, you will receive the recording via email on January 30 along with helpful resources provided by the speakers.
Native Seed Starting
The seed drawers at the seed library are bursting with native plant seeds! My last count had over 400 seed packets to choose from. There’s still time to stratify your native seeds. An easy, fun and easy way to start native seeds is using the winter sowing method. See below for directions.
Winter Sowing
Most native plants produce a flower which, if pollinated, will make a seed head or pod. Late in the fall collect the seed pods and allow to thoroughly dry. Remove the seeds before placing in paper envelopes or paper bags. Store in a cool, dry location. It is important seeds are dry before storing to prevent mold. Most native seeds require a moist cold period of time called stratification before they will germinate.
Germination Methods
Many native plant seeds have a dormancy mechanism that helps them to germinate at an optimal time. This prevents them from germinating right before winter or during a drought.
Easiest Methods: The easiest way to grow native plant seeds is to plant them in the late fall and let them go through the winter where they will sprout in the spring. Another way is to do snow sowing, used mostly for large sites. Prepare the site for planting in the fall. During the winter, scatter the seeds on top of the snow above the prepared site. As the snow melts in spring, the seeds will sink and germinate on the soil surface.
Winter Sowing Method
1. In late fall or early winter, prepare containers for growing seeds. Take a clean one gallon clear or semi-clear plastic container (such as a milk or water bottle) and poke holes in bottom and all over the sides and top of the container. Be generous with your holes. This is needed so water can get into and out of the container. Remove lid so that water can also get in through the top.
2. Cut 7/8 ways around the diameter about 6” from the bottom. Leave the top part attached by a small piece of plastic as the ‘hinge’. You are making a little greenhouse.
3. Turn the container over and label the bottom of the container with a permanent marker with the type of seed you are planting. Labelling the bottom prevents fading of the marker due to sun and rain. Yes, even permanent markers will fade in the sun, rain and snow.
4. Fill bottom of the container with at least 4” of potting soil. Use any kind, but don’t use soil from your garden as it is too heavy in texture and may have diseases.
5. Plant seeds in the soil to the depth stated on package. A good rule of thumb is to plant seeds to the depth of 2 ½ the diameter of the seed. Some seeds need light to germinate, which means don’t cover them, just sprinkle on the top of the soil.
6. Water until moist.
7. Replace top part of container and close with a piece of duct tape on the corner opposite the hinge. You just need one piece of tape to hold the lid in place so critters can’t get in to rummage around in your soil. Do not tape the entire sides. It is not necessary and some water will get in through the sides, which is a good thing.
8. Place containers outside in a sunny location. Yes, you put them outside in the winter in the cold. The seeds need a period of cold moist stratification before they will germinate. If you have persistent critters you may need to secure your mini-greenhouses so they don’t cart them off or play with them.
9. No need to do anything with the containers until spring. Check containers periodically to make sure they are still moist. Start checking containers as early as March. Things heat up quite a bit inside these little greenhouses on sunny days. There may still be snow on the ground, but it could be warm enough inside them to cause the soil to be dry. Remember seeds need moisture to germinate. You may have to open the tops on very warm days or when seedlings outgrow the container.
10. Transplant seedlings in the spring to your garden. No need to harden off seedlings as they have been growing outside all the time!
Moist Sand or Coffee Filter Method
You need to simulate winter by placing the seeds in moist sand or between a folded moist coffee filter and storing in the refrigerator for a set number of days before starting inside. Find the number of days to stratify on online or catalog sources.
Place a handful of moist fine sand in a plastic bag. Add seeds and mix. Or moisten a coffee filter and place seeds on filter and fold in half. Place filter in plastic bag. Label bag and place in refrigerator for the required number of days needed to stratify. Check bag occasionally and add water to keep moist. After appropriate number of days has gone by, place sand and seeds in potting soil medium in flats or pots and grow as you would other seeds.

Seed Packaging
The next seed packaging will probably be sometime in February. It will be on a Saturday that doesn’t look like it will have inclement weather! I’ll send an email and post a flyer at the White Bear Lake seed library when the date and time has been set.
If you would like to package seeds at home, send me an email and I will make up a bag of seeds and supplies you can pick up at the library.

Native Plant List
I have updated the online list of native plant seeds at the library. Note that this is a constantly changing list and was only accurate at the date listed at the top of the document.

An Act Locally Opportunity!
I want to make a request for locally grown tomato, lettuce, bean or pea seeds you harvested from your garden. Though the seed library gets donations of commercial seed packets, I especially like getting locally grown seeds. These locally grown seeds have started adapting to our local environment and in time will grow better than produce, flowers and seeds from plants grown elsewhere in the country.

Local Greenhouses and Nurseries
As a request from our volunteers, I am adding a list of various local greenhouses or garden centers that sell plants. Many of these establishments do not use neonicotinoids on their plants that they grow. But the buyer should beware: they may sell plants that were grown previously at a different wholesaler which did use systemic pesticides. You should ask the growers at these establishments whether neonics were used on the plants you wish to purchase.
Neonicotinoids or ‘neonics’ are a systemic pesticides used on plants to kill insects. Unfortunately, these insecticides also harm pollinators as the insecticide gets into all parts of the plant including the pollen and nectar.
The only way to be sure a plant has not been treated with neonics is to buy certified organic seed and grow it yourself, or buy a certified organically grown plant.
