Stop Fruit Tree Diseases: Prevention Strategies for Stone Fruit and Cherries

Plums, peaches, and cherries are disease magnets. Proactive cultural practices prevent most common infections without heavy chemicals.

Brown Rot (Fungal)

• Attacks leftover fruit; reinfects new crop.
• Prevention: Prune for airflow; remove all mummified fruit from tree and ground after harvest.

Cytospora Canker

• Sunken, gummy lesions on branches; enters through old wounds.
• Prevention: Prune late-summer sprouts; let wounds heal naturally (no sealants).

Black Knot (Plums)

• Rough black galls on branches.
• Action: Cut out infected branches immediately; don't mulch infected wood.

Cherry Leaf Spot

• Favored by wet leaves on ground.
• Prevention: Rake all fallen leaves. Destroy if diseased; mulch if clean.

Harvest Discipline

• Pick ripe fruit daily; finish within 2 weeks.
• Remove drops and rotting fruit—prevents bee/wasp buildup.
