Professional Landscape Designer Suggestions to Replace Damaged Ash Trees

Autumn Blaze Maple to replace Emerald Ash Borer DamageBy now, most people know that the Ash tree population in central Ohio is being decimated by the Emerald Ash Borer.  Many homeowners, businesses, municipalities and golf courses are dealing with the unfortunate loss of these once beautiful shade trees.

Ash trees were long considered a favorite for those wanting a fast growing shade tree that were tolerant of a wide variety of growing conditions. Some of the improved cultivars of Ash such as Patmore, Marshall’s Seedless and Summit were extremely popular.  In fact, our company has planted hundreds if not thousands of them over the years.

Now that many people have had to remove their Ash trees due to infestation by the Emerald Ash Borer, we are often asked for replacement tree suggestions. Our professional landscape designers have compiled a list of suggestions based on several factors.  First, we wanted to pick out trees that are going to be medium to fast growing, but in order to make the list the tree must also be strong. Many trees that are fast growing are also “weak wooded” meaning that they have problems with branch breakage and are often messy.Red Sunset Red Maple to replace Emerald Ash Borer damage

Secondly, the trees needed to be reasonably available. It does no good to suggest a promising tree variety that has been recently introduced, but that have not yet had time to grow to a suitable landscape size at the nursery.

Third, in order to make the list the trees must be hardy for our area of central Ohio, which is USDA Hardiness Zone 6a.

Please note that since the primary value of Ash trees were for their abundant shade, this list contains suggested replacements that will provide shade.  If you are interested in a smaller,ornamental tree, please see my earlier blog article titled “My Favorite Ornamental Trees”.
