man I always have problems with sweet peppers, can grow everything else but peppers are always a problem. Anyway, my peppers were going great until the bottom leaves starting falling off, now only the tops are left, they are brown at the edges, at the middles, you name it. Only a few leaves left on the top but many new small leaves popping out of the main stem, like its trying to come back. I have two patches of peppers physically seperated, now I'm starting to see problems with the second patch, during hot weather six or seven of them get real droopy, even though the soil is damp and mulched, the others are fine but probably won't be for long. Brown edges are starting, is this a fungus? I read a description here and it sounds like the problem
In any case is it time to go get a gas mask and some fungicide? These are all in raised beds, cow manure and seaweed/fish emulsion fertilized (also compost from grass and leaves mix). I lime as needed.
Its funny, my neighbor plants his peppers directly underneath a huge oak tree, no mulch and his do great!(his tomatoes do horrible) My plants are in direct sun, do sweet peppers like semi shade?
