Many (maybe 15) years ago, I planted a couple dozen apple seeds, most which germinated. I sorted the most vigorous 12 and planted to small pots for anther year, then into semi-protected areas that were caged. Two years later, only three were hanging on, and now, after 15 years, only one is still alive and it is maybe 6' tall and on it's last legs. Moral for me... there is a reason people grow rootstocks and graft known varieties to them. I suck and at growing trees, and I am not much better at grafting... a nurseryman's best customer! I have to admit it is fun, so I have nothing against growing anything from seed - good luck guys!
