Marshall's seedless ash is a large deciduous tree with upright branches, spreading form and irregularly-shaped crown. Shiny deep green leaves turn yellow in the fall. Due to the presence of the emerald ash borer in Colorado, tree care professionals are no longer recommending ash trees be planted in Colorado.
This is a widely planted tree in the Colorado Springs area since it has been a reliable, attractive tree.
Prune when young to achieve a structurally sound tree. For existing trees, protect them from emerald ash borer once the insect is found within a 50 mile radius. It is currently limited to the Boulder/Denver area.
