Tree disease assessment

Asked July 14, 2018, 12:44 PM EDT

How can I get a reputable, objective expert to assess whether several large trees in my backyard have damage due to emerald ash borer or other insect that could cause them to deteriorate? Removing the trees would be very expensive.

Take a look at our website on the emerald ash borer, an invasive pest on ash trees. The emerald ash borer is in Maryland and is a problem. Begin by looking at our emerald ash borer page for more information http://extension.umd.edu/hgic/invasives/emerald-ash-borer

You will also see a link to ash tree identification. You will also see signs and symptoms of decline such as woodpecker damage, D shaped holes in trunk, etc.

Ash trees quickly become very brittle and dangerous as soon as they die. This makes them more expensive and problematic to remove. You may want to remove the tree before it completely dies, or at least as soon as it dies. It may be helpful to contact a certified arborist regarding the health of the tree and the best way to proceed. http://www.treesaregood.org/
