Can You Keep a Walnut Tree Small?

Yes, it is possible to keep a walnut tree small through pruning and other management practices. However, it’s important to note that walnut trees (Juglans spp.), especially those grown for their nuts, naturally tend to be large and can reach substantial heights if left unpruned.

Here are some tips for keeping a walnut tree small:
  1. Pruning:
    • Regular pruning is essential to control the size of the tree. Prune during the dormant season (late fall to early spring) to minimize stress on the tree.
    • Remove unwanted or excessive branches, especially those that are growing vertically and contributing to the tree’s height.
    • Head back the main leader to encourage lateral branching and a more compact shape.
  2. Dwarf Varieties:
    • Consider planting a dwarf or semi-dwarf variety of walnut. These varieties are naturally smaller than standard walnut trees and are often more suitable for smaller spaces.
  3. Root Pruning:
    • Root pruning can also help control the size of the tree. This involves cutting some of the roots to limit the tree’s ability to take up water and nutrients, thereby slowing its growth.
  4. Container Growing:
    • Growing a walnut tree in a large container can help restrict its size. However, container-grown trees require careful attention to watering and fertilizing.
  5. Training and Shaping:
    • Train the tree to have an open canopy, which allows better light penetration and air circulation. This can result in a more compact and manageable tree.
  6. Regular Maintenance:
    • Regularly remove any water sprouts or suckers that emerge from the base of the tree. These can contribute to unwanted growth.
