Admittedly, this is only tangentially related to food, but I know many of you are gardeners too (and wouldn't a gardening/farming hotline be awesome?). Anyway, some of the leaves on my young fig tree are turning brown in spots. A quick search on the Interwebs has me paranoid that my tree will die if I don't spray with fungicide or copper (?). Have any of you had experience with this? Will my growing figlets be inedible if I spray?
