I have two Black Ice Plum trees in my yard. I planted them about 6 years ago. I’ve been babying them and trying my best to prune correctly. Last year was the first year they really produced fruit. I harvested a few large bowls of plums and was so excited – until I cut into them… Inside almost every plum (except maybe 10) I found white “worms” that were alive. I am wondering what this might be? And how can I treat it? Or maybe you can point me in the right direction for learning more. The trees are totally organic. I haven’t put any chemicals on them – even organic fertilizer. But the fruit that had the worms had holes or scarring on the outside of the fruit. So I’m assuming they will need to be sprayed with something.
