I always plan numerous kinds of tomatoes, theres always just one more to try. all heirlooms. and, i dont have time to hand polinate and bag blooms. my question--if i save seeds, for myself only, will i get edible tomatoes? i'll have paste type, mostly stripe big ones, with pink oxheart, and a big red slicer to round it off.i know, i should get a mixed up bunch of seeds-but what i'm wondering, if i just save my own, will all be edible? or revert back to something non-edible?
