Question From: Vineland, New Jersey, United States
Q: My zelcova trees are dying. They have developed a white coating on the bark.
Gail, you need to get an on-site inspection from a certified arborist. To find a qualified professional in your area go to www.tcia.org. I am not trained to make an accurate diagnosis and there may be several issues which only can be seen onsite. Good Luck and thank you for visiting Yardener.com.
