Narrow-Leaved AshFraxinus angustifolia

Water young trees regularly, especially during dry spells, to establish a strong root system. Once mature, narrow-leaved ash is moderately drought-tolerant.

Allow the top few centimeters of soil to dry out between waterings. Overwatering can lead to root rot, so ensure good drainage.

Prune for structural integrity, to remove dead, diseased, or crossing branches, and to shape the tree. The best time for major pruning is during the dormant season (late autumn to early spring).

Minor trimming can be done after flowering if needed. Avoid heavy pruning in summer.

Narrow-leaved ash can be propagated by seed, which requires stratification, or by semi-hardwood cuttings taken in summer. Seed germination can be erratic.

Cuttings are often more successful for specific cultivar retention. Ensure cuttings are taken from healthy parent plants.

Repotting is generally not applicable to mature trees in their natural environment. For container-grown specimens, repot every 2-3 years in spring before new growth begins.

Use a well-draining potting mix and a slightly larger pot. Prune roots lightly if necessary.
