Additional Information

The Autumn Applause Ash has a dense and rounded form with excellent maroon fall color. Heavy crops of seeds on female trees cause litter, and these germinate freely making the tree slightly weedy. An unattractive ash flower gall (caused by mites) can develop on male flowers and persist into winter. Subject to storm damage, so plant in areas that shelter the tree from strong winds. Emerald Ash Borer is severely affecting all species of this genus. Damage can be prevented with the appropriate pesticide, but the treatment cost will eventually exceed replacement cost.
