Q. Our mountain ash has suckers

Our mountain ash has suckers or shoots at the base and we would like to know how to stop these. The tree is 6 feet tall and we brought it with us from our old place in a big pot. How do we prune these off and stop them from coming back? Thanks.

The suckers may be a result of the stress of being transplanted. Cut them off, keep them cut off, give the tree the best care possible, and in a short time it should stop sending the suckers out.

Q. Mountain Ash Tree Berries

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?

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.

Q. I have 3 cardinal mountain ash trees that won’t flower.

Each tree was bought 1 year apart and they haven’t flowered yet. How to pollinate trees if they haven’t flowered yet? Trees are around 12+ feet tall

Grows best in full sunshine with moderate amounts of water during the growing season. If your tree is young, it may take a few more years before it's mature enough to produce berries. If it's been established for 4-5 years and is still not blooming, it may need more sunshine or additional water during the growing season.

Without seeing it, or the symptoms in question, it would be very hard to say. There are many insects and fungus that will cause the death of trees, and also many environmental issues that could have caused the death as well.

In the meantime, this article will help you to narrow down what is killing off your trees: https://www.gardeningknowhow.com/ornamental/trees/tgen/sudden-tree-death-causes.htm
