Why Mature Pecans Drop Large Limbs: Brittle Wood and Preventive Pruning

Large limb drop in mature pecans isn't a disease—it's a species characteristic. Pecan wood is inherently brittle, and trees naturally shed heavy limbs, especially after wind or rain events.

Professional Management

Commercial growers conduct regular preventive pruning to balance canopy weight and reduce limb failure. For homeowners, the best strategy is hiring a certified arborist to assess structure and perform corrective pruning.

Attempting to "stop" limb drop entirely fights the tree's nature. Instead, manage the risk through professional care and accept that occasional limb loss is normal for this species.
