Hello to you knowledgeable Gardeners out there. I live in the city and I'm growing okra along my fence line. Something is eating my okra but I'm not sure what. I've seen ants and an occasional earwig. Is there a typical treatment I can use that's natural and effective without knowing specifically what's devouring the leaves? I'm also wanting to mulch to deter weeds and help with moisture retention. Could I get some thoughts on best practices of growing okra? Thanks!
