It's actually showing only 11 of my 14 fruit trees. I am located in Southern Ontario Canada aprox. 100km west of Toronto. The winters here can be very harsh. Drawf trees require less pruning than hedges of cedar, spruce or other full sized trees.
Apple trees fruit heavily but are subject to worms.
Some years I get a good pear crop. I've had no luck with nectarines although some success with peaches. My sweet cherry tree grew like a weed and gave me no fruit. My sour cherries don't grow but fruit like mad. Birds, rabbits and chipmonks are the spawn of the devil.
