We typically look at the 4th of July as the planning date with starting several plants indoors to be transplanted in late August or September when the heat breaks. That being said, there are several cool weather crops that with a little early frost protection can easily reach maturity and some leave in the ground for a winter harvest like carrots. Frost protection does not need to be expensive and can be used in the autumn and the spring. We can make another post about cost effective frost protection if anyone is interested. To begin planning the autumn garden, first check your average first frost date and count backward to find expected days for maturity. We will then use these days to select seed that has the best potential to mature. Remember that growth slows as the days become shorter, so allow a little extra time. Also for me, I can eat anything from a sprout with first true leaves to maturity, so as long as I do not let the frost take it out, I'm good. Next, how much bed area is available to plant now? For me in TN, I am planting soaked lettuce seed under my tomatoes. Will your bed area receive enough sunlight as the sun moves lower in the southern sky? Everything south of me is deciduous so soon to loose there leaves. Will you sow seeds directly or use transplants to save time? Probably by August you are looking to direct seed although many cold weather crops will have poor germination with soil over 75 degrees F. Are you ok using short maturity hybrid seed or do you want to stick with open pollinated seed? Once we know the answers to these questions, we can make a seed list that has the highest potential for success. Cool-season crops such as lettuce, spinach, kale, radishes, carrots, beets, turnips, and Asian greens may all have a place, depending on your climate and remaining growing season. Fall gardening is not about filling every empty space. It is about choosing crops that fit the season, the household, and the care we can realistically provide.
