Recently I added 4 apple trees to my 3/4 of an acre to go along with my 3 sweet cherry trees. Lately I have noticed some nurseries offering different varieties of sour cherry trees on sale. I am a sucker for a good cherry pie, so I was thinking about adding a sour cherry tree. I would like to add only one tree so that means it needs to be self pollinating and one that will mature quickly and produce a relative large amount of fruit in a short period of time maybe within a couple of years. Anyone have any suggestions considering the criteria?? Too is a whip a better choice than say a larger more developed tree-have heard that it will transplant and do better is this true? Thanks in advance!!
