Description
A majestic and fast growing tree that is often grown for its timber. Black Walnuts make excellent specimen trees, best suited to very large gardens, parklands and open spaces. Their grey, deeply furrowed bark and large pinnate leaves are extremely attractive, particularly in autumn when the foliage turns to buttery gold. Juglans nigra produces edible crops of walnuts which are often thought to have a better, somewhat earthier flavour than the common walnut. However they are considerably harder to remove from their shells! Height: up to 30m (98’). Spread: Up to 20m (65’).

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Walnuts make substantial trees and are suited to only the largest of gardens. They should be planted at least 9m (30ft) from any buildings. Grow walnut trees in moist, slightly acid, well drained soil in full sun. When growing walnut trees, choose a sheltered position as young trees are easily damaged by frosts. Prior to planting walnut trees, incorporate plenty of well rotted manure or garden compost into the soil, and drive a stake into the planting hole to support the tree once it is planted. Plant walnut trees at the same soil level as they were growing at the nursery, and use a tree tie to fasten the tree to the stake.
More Info

Nut trees do not suffer weed competition well, so keep weeds and grass clear from within a 30cm radius of base of the tree. In spring, apply a mulch of well rotted manure or garden compost to the base of the tree. This will help to retain moisture throughout the summer. Walnuts can be slow to establish and during particularly dry periods they will require watering whilst the root system develops.

Prune walnut trees between mid summer and early winter to develop a standard tree with a strong central leader. In the first year, remove laterals from the lowest third of the tree. Shorten laterals from the middle third of the tree by half. Leave laterals at the top third of the tree intact. In following years repeat the process, removing the laterals from the lower third of the tree that were shortened the previous year, until the desired length of clear stem has been achieved. By the fourth year the tree should have achieved a good height and further pruning can be kept to a minimum, removing only dead, damaged or misplaced stems.
