Plum Pockets

Plum pockets cause swollen, hollow fruit on plum and cherry trees, particularly in wet springs. Remove affected fruit from trees to reduce inoculum for next year. Improve air circulation through pruning. Avoid overhead watering. Apply fungicides preventively during spring bloom if disease pressure is high. Monitor your plants closely and implement integrated management strategies. Prompt removal of infected material helps limit disease spread.

Prevention works better than treatment for plum pockets. Choose resistant varieties when they exist, site plants where air moves freely, and maintain good sanitation by removing debris and infected material. When chemical intervention is necessary, timing matters more than product: apply protectants before the infection window, not after symptoms appear.
