The first year I gardened, several of the NE companies had plants that developed blight. Unfortunately, I had some of those. I managed to get a decent yield, but I could have waited to learn about blight-it would not have hurt my feelings ya know?
Anyway, mulch with hay or newspapers does indeed help. I’ll have to try that bleach thing sometime-haven’t heard of it before.
Oh yeah, be sure to stand UPWIND when you spray the bleach stuff. Don’t breathe this stuff. I wear one of the little facemask things you get at the drugstore when I spray this stuff. Just because.
