Culture Notes
Existing trees do not tolerate soil compaction or construction injury due to an extensive root system. The tree appreciates good soil and is probably not a good choice for poor, urban soils. It tolerates high soil salt concentrations originating from de-icing salt applications better than many other plants. Plants in containers tolerate moderately-high soil salt solutions up to about 6 mmhos/cm according to the saturated media extract method. It does not tolerate heavy clay soil with standing water in the planting hole. Established plants tolerate flooding well.
White Ash is resistant to heat, although it is native to moist locations, including river bottoms and well-drained upland sites. There is no fruit production on this cultivar but pollen from this male tree causes significant allergy symptoms.
The potential disease and insect problems limit use to parks and other areas where the tree will not be missed if it dies. White Ash which have not been properly pruned can break apart in wind storms, but it has better branch structure than seedling Green Ash. 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. Can be used as a street tree where there is plenty of soil space for root expansion and where cultural conditions are met. Used as a street and parking lot tree in central California. Wood is considered ring porous.
