Syrian Ash prefers consistent moisture, especially when young. Water deeply when the top 5-10 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering frequency in cooler months or after the tree is well-established.

Prune Syrian Ash primarily to shape young trees and remove dead, damaged, or crossing branches. The best time for structural pruning is during dormancy in late winter or early spring.

Avoid heavy pruning, as it can make the tree susceptible to ash dieback.

Syrian Ash can be propagated by seed, though germination can be slow and irregular. Stratification is often required.

Grafting onto hardy ash rootstock is a more reliable method for producing healthy, true-to-type specimens.

Repotting is typically only necessary for container-grown young trees. Choose a pot that is only slightly larger than the current one. Repot in early spring before new growth begins, ensuring good drainage.

Established trees are best left undisturbed.
