When I purchased my house last year I hoped that the tree with purple leaves in my front yard would produce fruit. Fortunately it has produced little plums about the size of a golf ball. This is my first experience owning a fruit tree so I apologize if the following is a silly question.
When I pick a plum that appears to be ripe, half of the flesh is sweet and the other half of the same plum is sour. I don't recall experiencing this with plums or other stone fruit I've purchased from the supermarket. In the supermarket stone fruit generally has a uniform flavor throughout. Is this a normal occurrence for little plums like these? If so is there anything I can do now to encourage the entire plum to be sweet now? If that ship has sailed what can I do so the plums are more uniformly sweeter next year?
