How to Manage Pests

Pests in Gardens and Landscapes

Planting

Plant from bare root during January and early February as soon as possible after receiving from the nursery. Do not allow plants to dry out. Walnuts can be difficult to transplant because of their deep tap root. Plant deep enough to accommodate the long tap root but no deeper than it was in the nursery. Be sure to plant in a location that can accommodate a large tree that has a spread of 40 to 50 feet. The planting hole would typically be 18 to 24 inches wide and 10 to 12 inches deep. Prune off any broken roots. Do not fertilize or add manures to the planting hole.
