TREE SPACING & PRUNING
A decade of Almond Board–funded research continues to challenge once-held assumptions about almond pruning and tree spacing and their impacts on efficient almond production.
To optimize production, the almond orchard should be designed and managed to maximize light interception through pruning, training and spacing while still allowing light to reach the orchard floor.
Research trials throughout California have demonstrated that there are many reasons to prune an almond orchard, but yield does not appear to be one of them. Trials have also confirmed that traditional tree spacing of 22 feet by 22 feet or more is too far apart to intercept the light necessary to optimize per-acre production in the orchard.
