Winter Sowing: An Alternative to Seed Starting for Northern Gardeners
One of my favourite ways to grow vegetables from seed is through winter sowing. This method allows northern gardeners to start seeds outdoors during the winter, using mini greenhouses created from repurposed materials. This ingenious method bypasses the need for indoor space, expensive grow lights, and the constant attention required by traditional seed starting methods.
Keeping Things Simple
The beauty of winter sowing lies in its simplicity and the minimal resources it requires. Traditional indoor seed starting demands space, specialized lighting, and a controlled environment to manage temperature and humidity. However, winter sowing utilizes the natural cycles of the winter weather to achieve a similar, if not better, outcome. Seeds are naturally stratified (exposed to cold temperatures) which breaks their dormancy, leading to a successful spring germination.
To begin winter sowing, you only need a few simple supplies, most of which can be found around your home. Here’s a basic list of what you’ll need:
Clear or translucent containers: 2L water or soda bottles, Milk Jugs, Salad Containers, or any plastic containers with a lid. Ensure they are clean and have holes poked at the bottom for drainage
Duct Tape: I like to use duct tape to seal my containers. However, you can use any weather resistant tape.
Potting Soil: Use a well-draining potting soil mix. Avoid using garden soil.
Seeds: Choose seeds that benefit from a cold start. This includes hardy annuals (Spinach, Kale, Broccoli, Cauliflower, Lettuce, Celery) or Perennials like Echinacea. You can grow frost tender vegetables like tomatoes, however these vegetables would go out later in the year when the weather is a bit warmer like in March.
Labels: I’ve made the mistake too many times of forgetting to label my containers. Use a waterproof label to mark your containers because it’s easy to forget what you’ve planted where.

Once your seeds are sown, nature takes over. The snow and rain will provide moisture, and the natural temperature fluctuations help with seed stratification. As spring approaches and the temperatures begin to rise, your seeds will start to germinate. This cost-effective, time-saving method of starting seeds eliminates the need for transplanting seedlings but most importantly produces hardier and healthier plants. Seedlings that grow in tune with the natural environment from the start tend to be more resilient and better adapted to outdoor conditions.
Whether you’re a seasoned gardener or a curious newcomer, I encourage you to give winter sowing a try. It might just transform your gardening experience as it has mine, offering a fulfilling hands-off way to grow a vibrant, diverse garden from the very start of the season.
