That can be attached to almost all advice posted here- that is why I mentioned my specific pest issue to qualify my advice as well as I could. The question is what are you comparing grafting to. If you aren’t comparing grafted heirlooms to similar tasting modern hybrids you are not addressing my point- leave the poor straw man alone, he needs some rest. It’s good to know the grafting is quick and easy, though, although not as easy as just leaving the plants as they grow.
