One potential issue we're keeping an eye on is a disease called late blight. You might remember it from 2009, when it wiped out tomatoes and potatoes across most of New England. Late blight can't overwinter here, but the spores get blown up on storms from the south, where it is present year-round. Usually it doesn't get here until late summer (thus the name), but it has been confirmed already in Massachusets and New York. Under organic management, there aren't a whole lot of options beyond pruning tomatoes well to encourage air flow and hoping for a good stretch of dry weather to slow down or stop the spread of the disease. Conventional growers can use several powerful anti-fungal sprays, but the only one available to organic farmers is copper, and it only really works if you use it before there are any symptoms. So we're pruning, and hoping, and keeping a close eye on the maps.
With luck, we'll have tomatoes for CSA pretty soon, and for a while!
