My family loves table grapes, specifically black seedless ones. Its gotten to the point that we'd like to plant a couple. I'm finding some good general information but nothing particularly inspiring! I would like to know 2 things... can they be grown successfully (as in people would still want to eat them) without pesticides? we can net them, but not able to keep up with spraying regimes. We like black seedless, could we plant multiple black(or red for variety) cultivars and still end up with seedless fruit or will they cause each other to seed.

Any help would be greatly appreciated!

thanks
