Growing your own fruit at home is fun. However, one may ask if it is really cheaper for one to pay for the upkeep of trees ( fertilizer, water, pruning, mulching, spraying) than to just buy fruit in store. Citrus used to be no maintenance when I was a kid in Fl, but I can tell you that I spend a lot more on upkeep of peaches, apples, etc, and of course winter protection for citrus here in NC. Native fruits however, such as paw paw and wild crabapple are no maintenance and I can pretty much call their produce "free fruit".
