Winter sowing impatiens is a great way to add a lot of appeal to flower beds for a very low cost. While many bedding plants can be easily purchased at the home improvement store, the cost can definitely add up quickly. Luckily for those of us on a budget, the winter sowing method is a great way to great the most for your money.
To winter sow impatiens, I usually wait until mid March here in zone 6b/7. By March, the weather has started to warm and the days have gotten longer. This allows for the consistent germination of impatiens seeds. Here in my yard, the impatiens are definitely sensitive to frost. Even though the seeds will germinate when the time is right, there is still very much a chance of frost.
If there’s a threat of frost, it will be important that I take measures to protect my winter sown seedlings from the weather. In many cases, this means that I’ll need to add an extra layer of protection to the containers. This can either be in the form of a row cover or even an old sheet. If you don’t have a row cover, bringing the winter sowing containers indoors for the night is always another option.
By sowing early, it’s easy to great a really great jump start on the garden. I usually transplant the impatiens into the garden as soon as all chance of frost has passed. When this occurs, the winter sown impatiens have at least three sets of true leaves.
