Answer: I'm sorry, but I'm not familiar with that tree, so I'm going to recommend that you contact your University of Arizona County Cooperative Extension office in Kingman. Their Master Gardeners or Horticulture Agent will be familiar with such local issues and can help you diagnose the problem. Good luck!
