Hey John, I'm in middle Tennessee and I grow spinach, but I don't bother with it in the summer. I find that when the weather gets hot, spinach gets bitter and it bolts. I've also found spinach and lettuce seeds won't germinate well in hot soil. I mean you can try a small patch and see what happens, but I have noticed on my spring grown spinach that stays in the soil into late may, some can be sensitive to sunburn. I really enjoy fall grown spinach, as they start getting large in the cool fall weather and into winter I find they are much sweeter than any I grow in the spring, and they also seem to lack any bitterness.
