My pepper plants had something wrong with them (picture attached) and after Googling, it seemed to be rust. It started on the bottom leaves and worked its way up the plant. For several weeks, I meticulously cut off all the bad leaves and sprayed with neem oil and Serenade (not at the same time). I finally gave up on stopping the problem and pulled up the peppers and got rid of them. The peppers were planted in a planter next to a Stevia plant and it never had the same symptoms. It is early enough in the season that I would like to get a couple more pepper starters and put them in the empty planter space, but I don't know how to tell if my soil is bad. Can I plant more peppers? Or should I plant something that isn't a nightshade? Or should I consider the soil contaminated and replace before next season?
Anyone have any ideas? Thank you SO much for your help.
