Walnuts are deciduous trees that can grow into large specimens. Depending on the species and the location, they can reach over 100 feet tall with large crowns. Suitable for large gardens, knowing how and when to prune a walnut tree keeps it healthy, productive, and looking its best.
Walnut trees are slow-growing and prone to bleeding sap post-pruning. It makes bad pruning choices especially problematic, as the tree is left susceptible to pests and diseases for longer and new growth takes time to cover up any scars. The best time to prune trees is towards the end of dormancy, although walnut trees can be pruned in summer too.
