Plum Tree Shot Hole and Bark Bumps: Separating Insect Damage from Normal Lenticels

Assessing the Symptoms

• Tattered leaves, not clean round holes: Suggests insect feeding, not classic shot hole disease.
• Bark "bumps" with green underneath: Likely lenticels—normal gas-exchange pores, not pests.
• Peeling bark layers: Could be natural exfoliation or minor injury response.

Management

1. Rake and destroy fallen leaves early spring (before bud break) to reduce pest carryover.
2. Monitor new growth for actual shot hole (distinct round holes) or pest activity.
3. No spray needed now—targeted treatment only if pests confirmed.

Mulch Note

Leaf mulch may harbor pests but also benefits soil. Compost thoroughly before applying.
