When the colder temperatures hit you can protect your fall harvest by covering the plants at night with blankets from your home and frost blankets they sell at the garden center. If you enjoy succession planting and getting another crop of edibles from your garden in the fall, you can also build cold frames and hoop houses over your raised beds.
If you have always been a summer gardener, give second season gardening a chance. I have found that I stress a lot less about the garden in spring when I know I have a second chance of growing a lot of things at the end of summer. Even if you don’t plant a second season vegetable garden this year, I encourage you to visit some urban and rural farms and see what they’re planting for the fall in your area for ideas for yourself. I have learned so much about vegetable gardening in late summer from talking to people who garden for production and sales.
What are you seeds to sow in summer for a fall vegetable harvest?
