BB-Sized Bumps on Oak Branches: Galls or Scale? Stress is the Root Cause

Identification

Hard, crunchy BB-like growths could be gall wasp galls or scale insects. Without seeing larvae, exact ID is difficult.

Why They’re There

Insects target stressed trees. Stressors include:

• Over-fertilization (nutrient traffic jam lowers sugar levels)
• Overwatering or root damage
• Improper pruning

Approach

• Atomic Grow foliar spray: claims to remove larvae, clean stomata, raise Brix, and restore balance.
• Address stressors: Soil test, adjust watering, use slow-release fertilizer, hire certified arborist for pruning.
• Monitor: If galls, they may not harm tree long-term. If scale, treat with horticultural oil in dormant season.

Healthy trees resist infestations naturally.
