Infested trees start to die back from the upper branches. They start to this and then die. You may also notice suckering or water sprouts around the trunk lower on the tree.
Should you treat your ash tree?
We do not recommend treating all ash trees.
Once you start treating your ash tree you will need to continue treatments for the rest of the life of your tree. That is an added expense you may want to avoid. The cost of the treatments increase as the trees get larger. The ash trees we would recommend treating we be as follows:
- The tree is healthy.
- It is providing a useful benefit to the site. This is generally providing shade that may allow spaces to be utilized more or help to reduce heating costs of buildings.
- It is one or one of only a few mature trees on a site.
If the tree is unhealthy, very small, or is one of many on a site, you may be better off removing and replacing the tree. See a list of potential replacement trees below. Please feel free to reach out to us if you would like to find out what we would recommend.
