I have some native plums. Last year after reaching a small green olive stage every single plum grew distorted and turned grey and felt like they were styrofoam. What happened? Can I prevent it?

Sounds like a disease called plum pockets. It is related to peach leaf curl. The controls are the same applying protectant fungicides in the early spring at bud break. http://www.extension.umn.edu/garden/yard-garden/fruit/integrated-pest-management-for-home-stone-frui...

Here is an article on peach leaf curl and its control. http://msue.anr.msu.edu/news/treat_peach_leaf_curl_now
