Since I’ve started posting about seed starting and winter sowing, one of the most common questions I get is “what do I winter sow and when?” This year, I’m attempting to help answer that question by making a series of posts showing what plants I’m actually planting each month. I generally start the winter sowing process around January 21st. This is around the same time that the day length in my growing zone surpasses 10 hours.
My last frost date is usually around the first week of May. This means that there is still tons of cold weather left in the season. Therefore, I’ll need to focus on plants that are able to withstand the cold should they germinate early. Most of the seeds I’ll be planting now are hardy annuals or perennials. It is especially easy to winter sow these types of seeds because many of them need a period of cold stratification.
Once the seeds have been sowed, they’ll germinate when the time is right. The important thing to remember about the process is that these seedlings will be transplanted out into the garden before the last frost date. I usually transplant as soon as the soil can be worked in the spring. This will ensure that the plants have plenty of time to get established before the heat of summer arrives.
