Narrow-leaved Ash

Narrow-leaved ash is a large, fast-growing deciduous tree with glossy, slender leaflets and an open, spreading crown. Small greenish flowers are inconspicuous, while the foliage turns yellow in autumn and winged fruits may follow. ## Size and siting The [RHS profile](https://www.rhs.org.uk/plants/7300/fraxinus-angustifolia/details) describes a mature tree reaching about 25 m, with a broad spread. Choose a site with room for a substantial canopy and keep it clear of structures and overhead services. ## Growing conditions Plant in full sun in fertile, well-drained soil. The RHS lists chalk, clay, loam, or sand and an alkaline-to-neutral soil reaction; it also notes that the species can suit woodland and coastal gardens. Its narrow leaflets give the canopy a finer texture than many large shade trees. ## Maintenance Allow the crown to develop without crowding and prune only to remove damaged or poorly placed branches. Check local guidance on ash health and planting suitability before adding this large tree to a site.
