Ash should be grown in full sun or partial shade and prefers moist, rich soil, and grows well on calcareous soil. Grows best on deep soils with adequate moisture, although drought tolerance is moderate. It tolerates poorly-drained, low-quality and alkaline soil. Its use is probably limited by borers which often infest the trunk and cause the tree to decline. Probably best suited for landscapes with plenty of soil space for root expansion, not in confined urban soil.

Makes an obvious choice for along streams and rivers. Trees are very susceptible to damage from ice loads. Ash are among those susceptible to summer branch drop according to surveys in California. Summer branch drop is a phenomena resulting in failure and breakage of large diameter branches typically on calm summer days. Wood is considered ring porous. Pollen causes significant allergy symptoms.
