If I understand correctly from other reading, tomatoes are more likely to self pollinate than to be cross pollinated by insects or bees. I've never done this before, but I hope to purchase some little drawstring organza bags and when I've seen the flowers begin to form, I hope to cap that stem off with the organza bag to insure no cross pollination. Since I hope to grow mine in large containers or buckets, they will be sitting close to each other, different varieties. I don't even know how many flowers will be on a stem or cluster, or even approximate; but as I see that the flowers are gone, I will remove the organza bag and somehow mark that stem cluster for future harvest of seeds.
