Additional Care Tips

Green ash prefers consistent moisture, especially when young and establishing. Water deeply once or twice a week during dry periods, ensuring the soil is moist but not waterlogged. Mature trees are more drought-tolerant but benefit from supplemental watering during extended droughts to maintain health and vigor.

Prune to remove dead, damaged, or crossing branches. The best time for structural pruning is during the dormant season (late winter to early spring). Light shaping can be done in summer. Avoid heavy pruning in fall, as it can stimulate new growth that may not harden off before winter.

Green ash can be propagated by seed, which requires stratification (a period of cold, moist treatment) to break dormancy. It can also be propagated by cuttings taken from semi-hardwood in summer or hardwood in winter. Grafting is also an effective method for specific cultivars.

Repotting is generally not applicable to mature green ash trees as they are large landscape specimens. For young trees grown in containers, repot them into a larger container every 2-3 years, preferably in late winter or early spring before active growth begins. Use a well-draining potting mix.
