Yes, you can garden in winter. It’s called Winter Sowing. Have you ever heard of winter sowing? Winter Sowing is a method of propagating new plants for your gardens simply by starting seeds outdoors in the winter. Several years ago, I read an article in Northern Gardener Magazine written by a master gardener, with whom I later became acquainted. After seeing the results of Michelle’s winter sowing, I knew I had to try it. It’s so incredibly easy and a great way to get some beautiful perennials for your flower gardens for super cheap.
There are different methods of winter sowing, but I’m going to stick with what I know and what has worked for me.

Supplies Needed for Winter Sowing:
- Several clean, plastic, gallon-sized jugs or plastic deli containers (that are at least 4 or 5 inches deep). The containers should be somewhat transparent so the sun can shine through them.
- Potting soil – I just use a cheap potting soil. You don’t need anything with fertilizer in it.
- Seeds – (I winter sow mostly perennial and hardy annual seeds, but check the bottom of the post for more information on sowing tender annuals and vegetables.)
- Sharpie or permanent marker that won’t fade (I use these paint markers.)
- Plant tags or labels
- Clear packing tape or duct tape (I use this packing tape.)
- A sharp knife or scissors
- Free printable Winter Sowing Chart – this chart helps me keep track of what I’ve sown and the results.
Seeds that work well for Winter Sowing:
A large part of gardening and learning is experimentation, so if you’re curious if a particular seed will work for Winter Sowing, go ahead and try it, cause you really don’t have much to lose. Here is a list of seeds that I’ve had success with Winter Sowing:
Perennial Seeds for Winter Sowing:
- black-eyed Susan
- balloon flower
- shasta daisies and painted daisies
- meadow blazingstar liatris (butterfly magnet)
- blanket flower (gaillardia)
Annual Seeds for Winter Sowing:
- morning glory
- black-eyed Susan vine
Steps for Winter Sowing:
- If you use gallon jugs, cut them around the middle neatly on three sides, leaving 5 or 6 inches on the bottom. You can discard the caps.
- Poke some drainage holes in the bottom of your container.
- Fill your containers with 3 – 4 inches of soil. Pack it down to fill in air pockets. Water the soil to get it fairly moist but not soggy. At this point make sure the drainage holes in the bottom of the container are working.
- Plant your seeds according to the directions on the packet. If you don’t have the seed packet to refer to, as a general rule-of-thumb, the smaller the seed, the more shallow you plant it.
- After your seeds are covered, give them a light sprinkling of water (I use a spray bottle). Skip this step if your soil is already moist.
- Next you’re going to tape the lid or top of the jug to the bottom. Poke some holes in the top of your taped up container for ventilation. And there you have it – a little green house. As you can see in my pictures, last year I forgot to take the caps off. Oops, I still had great results though.
- Write the name of your seeds on the container. Make sure to use a marker that will withstand weather elements. I also put a plant tag inside the container too.
- Place your container(s) outdoors. Select a spot where your little greenhouses will be safe from wind and animals, but be sure they are exposed to the elements. They need moisture from snow and rain. Some seeds like perennials need a period of freeze and thaw (called cold stratification). I put my containers on the deck where I can see the containers and watch them in the spring.
- Now all that’s left is waiting for nature to do it’s magic.
I just have to share this handy Winter Sowing Chart that I’ve been using
to keep track of the seeds I’ve winter sown. Next year, it will be so helpful
to be able to refer to it and see what worked and what didn’t. Just added is
a Winter Sowing Checklist so that you can check off steps as you go.

When the weather starts to warm up in the Spring, you’ll be able to see your seeds sprouting. At this point you’ll need to make sure your new sprouts are getting enough water and ventilation. Poke a few more holes in the top of your containers and/or loosen some of the tape to allow for more air flow. The little seedlings will enjoy some days with the lids opened completely and then closed back in the evening.
Once it warms up and frost isn’t an issue, completely remove the lids. At some point, I will either divide and transplant the seedlings into bigger individual pots or directly plant them in my garden.
My winter sown plants are always very healthy looking plants. Here are a few of my successes from my winter sowing last winter. I’ve always wanted to have a large patch of Foxgloves, so I’m working on that patch of foxgloves by winter sowing. I’ve also had great success with Painted Daisies and the bunnies thoroughly enjoy this addition to the garden. Delphinium is another easy winter sown perennial and is always a lovely addition to any flower garden.
Depending on the perennials selected, the first year they may not flower, but the next year they will and they’ll just keep getting bigger and better each year. Is there a perennial you want to try, but don’t want to shell out the money for it? Well, winter sowing is a great way to get it for practically nothing. So, go ahead and give it a try. Play around with it, experiment and keep track of what works best for you. You’ll be so glad you did!
