broom hickory

Also known as: brown hickory; hognut; pignut hickory; small-fruited hickory; pignut

A very large, slow-growing deciduous tree with an oval-shaped crown and deep root system, also known by its common name of 'pignut hickory'. It can reach a maximum height of around 30m, but is smaller if cultured. Smooth, grey bark in young specimens turns to a textured brown as the tree matures and the pendulous foliage emerges brownish-green, changing to glossy pale green in the summer and then finally golden-yellow in the autumn. Fruits are nut-like and pear-shaped with a brown shell, and only appear on very mature specimens. Although edible, they are very bitter and tend to be favoured more by wildlife

Watering

Fertilizing

Balanced perennial feed every four weeks from spring through summer

Pruning

Little pruning is needed. Remove diseased, damaged, crowded or crossing shoots and unwanted growth. Timing depends on the plant: generally late winter or early spring; plants prone to bleeding and deciduous magnolias need different timing, and deciduous azaleas and lilacs are pruned after flowering.

Propagation

Propagate by seed; seedlings rapidly develop a deep tap root and resent disturbance so plant out in permanent position in the first year

Growing

Grow in a deep, fertile, humus-rich, moist but well-drained soil in full sun or partial shade. See tree cultivation for further advice
