Question From: S. Hammer - Dzerzhyns'k, Donetsk Oblast, Ukraine
Q: There is black on the edges of my new mountain ash and it looks like they are curling up and dying. I have another tree about 40 feet away and not sure what type it is but I noticed it on there first. Don't see any bugs or any thing just the black almost like a tar look. I had to put in an American zip code but I'm actually locate in Zone 3 central Alberta Canada.
If it were my tree I would get an on site inspection from a certified arborist, a trained tree doctor. I am not trained in the care of trees. Best And Happy Yardening, Nancy
