White Ash Tree

White ash is a large deciduous North American tree with a straight trunk and a rounded to pyramidal crown. Its compound leaves provide summer shade before turning yellow, maroon, or purple in autumn, and mature trees need generous space. ## Landscape use University of Illinois Extension gives a typical mature height of 50 to 80 feet and lists white ash for shade and street plantings. North Carolina State Extension describes a broader range of 60 to 90 feet tall and 50 to 75 feet wide, reflecting variation among trees and growing conditions. ## Growing conditions White ash grows best in moist, well-drained soil and tolerates full sun to shade. The [N.C. State Extension profile](https://plants.ces.ncsu.edu/plants/fraxinus-americana/common-name/white-ash/) notes tolerance of drought and wet soil after establishment, but also warns that emerald ash borer makes new ash planting inadvisable in affected regions. See the [Illinois Extension profile](https://web.extension.illinois.edu/hortanswers/plantdetail.cfm?PlantID=209&PlantTypeID=7) for cultural conditions and hardiness information. ## Maintenance Inspect for dieback and structural problems, and check current local pest guidance before planting. Female trees may produce fruit that needs cleanup near walks.
