I don't have much room for a veggie garden, though I'd like one - just a few tomato plants this year (and the garden herbs). But I usually have a couple mounds for squash and pumpkin. Last year a powdery mildew of round white spots turning to black decimated my squash vines, and no amount of fungicide (I tried three different kinds, and a vinegar spray someone suggested, before giving up) had any visible effect. So I've left off for this year, and next year I'll start them in a different area and blast the young plants early and often. Anyone had experience of controlling such blights, or killing old spores - cause I'll bet there's plenty just waiting?
