FRAXINUS EXCELSIOR – ASH, EUROPEAN

Common 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 soil. Its use should be limited, because of its susceptibility to borers which often infest the trunk of stressed trees. Probably best suited for landscapes with plenty of soil space for root expansion, not in confined urban soil.

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 from male trees causes significant allergy symptoms; females produce no pollen.
