Winter Sowing-A Different Technique

Plant Seeds Now Out in the Cold-It Works!

I’m hoping I have your attention by now. Maybe you think I’m crazy!

Believe it or not, it is possible to plant seeds in containers now, place outdoors in the snow, and they will germinate in the Spring. The technique is called Winter Sowing.

I have been using this technique for over 5 years now, and I‘ve had good results each year.

The best results will be with cold hardy, short season vegetables such as kale, lettuce, spinach, onions, leeks, radishes, and Brussels sprouts. Tomatoes and peppers will also germinate, but will be delayed compared to those started indoors and will mature much later. The nice thing is that seeds sown this way require absolutely no care once planted, until they germinate. The containers are planted and frozen in time.

This can be used also for some flowers, although I only have tried vegetables. For a great source of information on this technique including lists of seeds that will successfully germinate using this method, visit WinterSown.org.

Winter Sowing is actually pretty simple. Start with a one gallon milk or water jug that is clean. Remove the cap, and cut the jug in half except to leave one area to act as a hinge. Drain holes should be drilled or poked in the bottom to allow for proper drainage. The containers will not need to be watered once placed outside.

Fill the containers to about one inch from the top with a good growing medium. I tend to use potting soil as opposed to seed starting soil since potting soil normally is better at retaining moisture. Seed starting mixes tend to be very light and will dry out quickly.

Thoroughly wet the soil while allowing excess water to drain through the drain holes. Obviously this is best done in a sink. Once wet, lightly tamp down the soil to create a uniform planting surface.

At this point the containers can be planted and seeds covered to the recommended planting depth. Use a spray bottle to wet the soil again as to not to disturb the seeds. Again gently tamp the soil.

Once planted, the containers can be sealed. I normally use duct tape, but clear package tape will work also. Make sure you get a good seal so the containers can be carried without separating . The cap is left off the container when placing outside. This will allow rain rain to enter once the snow eventually becomes rain as Spring approaches. Once outside, watering will not be needed until the seeds germinate.

Place the containers outside in a spot where they will not tip over. If necessary, even dig into the snow to create a level spot. Snow will not hurt them, they can be completely encased in snow.

As you can see, I planted Romaine Lettuce, 2 types of Kale, Scallions, and Pak Choi. The containers will be like a time capsule. Plant it and forget it. To be re-discovered in Spring, when you will find yourself peeking in through the tiny opening to see if any seeds have sprouted. In the meantime, no maintenance necessary. Just relax and wait for Spring.

Stay tuned for updates.
