Additional Information

'Windy City' is an upright tree with an oval habit and strong branching. This hardy cultivar is also resistant to frost-cracking and has semi-glossy foliage with a handsome, rich 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. 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.
