The complicated bit is selecting a good variety, but if you can get a good variety, then they are very easy to grow. Didn't mean to discourage you just wanted to let you know that it is worth the trouble to seek out one of the modern grafted varieties on a rootstock for your area. Now that I have a good tree, it needs heavy fertilization & pruning once to twice a year, and that's it. No spraying needed. I got mine at plan o gram if that helps. The owner is very knowledgeable if you have the time to stop by his place.
