In my backyard (including the side fence) I have - 1 cherry, 2 sour cherries (different varieties), apricot, Japanese plum (2 way), 4 European plums (different varieties), 3 lemons (different varieties), a grapefruit, lime, kumquat and a bitter orange, 23 apples (each is a different variety), 10 hazelnuts (4 different varieties). I think that's it for fruit trees. There's also seven raised garden beds for vegetables and a number of perennial vegetables, an enormous pin oak, lots of irises, tulips, and a herb garden in my normal suburban backyard. We have a large house and less than a fifth of an acre in total. We are self sufficient in fruit. We have no lawn, but people rarely realise just how many fruit trees we have. The front yard is all native plants.
