Growing to an eventual height and spread of 9 x 7 metres in 20 years, Juglans Nigra provides a large specimen tree. The foliage, which is fragrant when crushed, is large, oblong and purple-green when young, turning to green in the summer and then yellow, bronze in the autumn.

Tasty black walnuts are formed, encased in green fruits on older trees in the autumn. With a pleasing rounded shape, this Black Walnut Tree will grow in any well-drained soil in sun or partial shade and exposure can be tolerated. Juglans Nigra makes a pleasant addition to any garden.

Planting Advice for Juglans nigra Trees

Our pot grown Black Walnut trees can be planted at any time of the year. Firstly, remove all weeds and grass within a metre of your desired planting hole. Dig a hole as deep as your root mass and approximately 2x as wide. To help your tree establish more effectively, we advise applying root grow (sprinkle in the hole for pot grown trees).

Gently loosen the tree roots and place into the planting hole. If your soil is poor, mix 50% of the original soil with 50% high quality compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree. We recommend planting this tree with a stake and tie and, if your area is prone to rabbits, a rabbit guard. For further information, visit our advice section.

Aftercare Advice for Juglans nigra Trees

If you’re planting Black Walnut trees in spring, summer or dry weather, water well and regularly for the first few months. Increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We stock a range of irrigation kits.

Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons.

Pruning Advice for Juglans nigra Trees

American Walnut trees do not require regular pruning. If you wish to tidy up your Walnut tree, do this during the dormant season. Focus on removing any damaged, diseased or overcrowded branches. If you require a clear trunk, remove any side shoots to help raise the crown.
