Well, the local farmers mostly grow cotton and sorghum, but I’d bet a lot of them grow gardens too. There’s also the county extension service, I suppose.
We do have an early and a late season; one year the hornworms ate the tomatoes back to bare stems and the plants were bearing again before first frost. Never really stays cold enough long enough to let fruit trees do much, though.
We found the hornworms one year...yuk...but we drowned them, fed them to the birds and the tomato plants went on to lead successful lives feeding my family well into late fall.
