Mountain Ash Tree Berries

Question

I have a mountain ash tree in my yard which has produced many clusters of berries each year. For some reason, this season did not produce any berries at all. The tree is over 20 years old and has always produced lots of berries until this year. What could have caused this?

Answer 1

Did you have a late frost in the spring? Many parts of the country did this year and is likely what happened to you. These late frosts killed the flowers on the trees and without the flowers, the tree cannot produce berries or fruit.
