Question From: n. chocker - Kimberly, Idaho, United States
Q: I have blue spruce trees that have oyster shell scale in certain areas of the trees. I am fearful to spray any oil sprays on evergreens. I have great luck using neem oil on other insect problems in my yard. Will it be safe on these trees or am I risking burn?
I am not trained in the treatment of diseases of trees so I cannot advise you. If they were my trees I would have them inspected by a certified arborist, a tree doctor. To find a professional in your area go to www.tcia.org. Best Nancy and thanks for visiting Yardener.com.
