China Berry Stump Sprouts: Garlon 4 for Resistant Species

China berry (Melia azedarach) cut down; Roundup fails to stop root sprouts. Homeowner asks for effective herbicide.

Why Roundup Fails

China berry has waxy leaves that shed water-based herbicides. Also, extensive root system stores massive carbohydrates, fueling persistent resprouting.

Effective Alternative: Garlon 4 (Triclopyr Ester)

• Oil-soluble; penetrates waxy cuticle.
• Apply as foliar spray (1–2% solution) to actively growing sprouts.
• Or cut-stump: 20–25% in basal oil, paint fresh cuts.
• Best timing: late spring–early fall, full leaf, active growth.

Precautions

• Non-selective—kills broadleaf plants. Avoid drift to desirable trees/shrubs.
• Do not apply near water (check label for setbacks).
• Wear chemical-resistant gloves, eye protection.

Persistence Required

Multiple applications over 1–2 seasons typically needed. Monitor and retreat every 6–8 weeks during growing season.

Garlon 4 is the professional standard for tough woody resprouts like China berry, tree-of-heaven, and buckthorn.
