Tips for getting seeds started in the heat of summer.
Q. How can I get fall-veggie seeds to sprout when it's blazing hot (and dry) outside?
A. Some seeds do have trouble germinating when it's hot, but sprout they must if you're going to have a fall vegetable garden. Here are some tips for getting them started:
To determine when to plant, subtract the number of days to maturity (listed on the back of the seed packet) from the average first frost date in your area. Some semi-hardy vegetables such as spinach, lettuces, Swiss chard, radishes and beets can tolerate a light frost and temperatures down to 30 degrees or so. And some hardy plants such as broccoli, kale and cabbage can handle several frosts and temperatures down to 22 or so.
