I've been using Sevin spray, need to get more dust.
Seth -- I start as much of my own stuff as I can inside. Usually maters, peppers, onions and herbs in January, other things later. Stuff gets transplanted or planted according to its particular needs. Onion and lettuce transplants in March. Pea, beet, radish, spinach seeds in mid-March. Average last frost date here is Tax Day, so maters and peppers are transplanted out no earlier than that. Actual day depends on how much hardening off I've been able to do and what the short-term forecast says. This year they went out April 27, and I planted beans and some other stuff then too. We got a late light frost 5/18 but it wasn't too bad.
But, hey -- I'm not harvesting beans and peppers, so what do I know??
