My first packets of seeds have come in the mail and I’m so eager to start gardening, but the 10 inches of old snow that’s still all over my garden is a real obstacle. My lights are reserved for tomatoes and peppers….but I want to Garden NOW. When I’m in this predicament, there’s only one thing to do: head out to the recycling bins and dumpster dive for plastic milk jugs and salad containers and all other types of clear plastic to start some seeds in.
Winter Sowing is my favorite way to start wildflower seeds but it works for all seeds. Winter Sowing is all about starting your seeds outside and letting nature’s natural rhythms stir the seeds to life at the right time. It’s also all about getting LOTS of plants practically free without having extravagant indoor light setups or greenhouses.
There’s lots of info online about Winter Sowing…a term coined by the Queen of Winter Sowing, Trudi Davidoff, back in the early days of the internet on the Garden Web forums. Trudi has it all consolidated on her web page www.wintersown.org with answers to every question you can possibly have. We all love Trudi because she took something rather mysterious…making new plants…and made it easy and almost foolproof.
To make it even easier for you, here’s your “Short Form” Winter Sowing Instructions:
1. Recycle a plastic container. I’m fond of the gallon water jugs but any container with a clear lid that you can put holes in the bottom works.
2. Label your container at least twice. Sharpies aren’t really permanent so I use an art deco paint pen from Michael’s to write directly on the container or on a strip of duct tape.
3. Put in 2-4 inches of potting soil. Wet the soil. Sprinkle the seeds on top. Lightly water the seeds into the soil or press them with your fingers.
4. Secure the top of the container with duct tape. Place the container outside where the wind won’t blow it over.
5. Check periodically (twice a month) for watering. This is really important. If the soil dries out completely, this seeds will likely die because germination had already started. If you can see condensation on the inside of the container you’re probably OK. A foot of snow on top is probably also a safe sign.
6. Beginning in April or May here in Zone 5, anytime after the seedlings come out you can plant them directly into the garden.
Timing is the beauty of this method…On cold winter days, you yearn for spring and have more time for starting seeds. In my experience, the plants started this way are much sturdier than ones started indoors under warm conditions.
Winter Sowing is an ideal technique for wildflowers. You can start now and keep making containers when you have time until as late as March or April.
