Emerald Ash Borer

Asked June 15, 2015, 11:57 AM EDT

We have several Emerald Ash Trees near our house which appear to be stricken..(e.g., bark falling away). Is it avisable to have them cut down, or can they stay and serve for squirrels, birds, etc. Will they become brittle and in danger of falling over? Any advice would be appreciated.

Ash that dying (especially from EAB) tend to dry out quickly and become brittle.

If this tree has the potential to impact the house, street, patio, cars, or people, I would remove it immediately. The longer you wait, the more expensive the removal will become. If the tree becomes weak and brittle, a tree service cannot send a climber up the tree to remove it in sections. Once it is unsafe to climb, they would have to use a crane to remove the tree.

Hope this helps.

Many thanks. MOST helpful.

I would recommend cutting them down as soon as you can. Ash wood dries out and becomes brittle. If it is next to a house, it will cost more to remove as it becomes brittle. An arborist cannot climb a brittle, unsafe tree so a crane might be needed if it is left too long.
