Weeping Cherry Borer Damage: Merit Insecticide and Fertilizer

New weeping cherry oozing sap, sprouting at base, trunk looks snake-bitten with swollen bark and sap leaks.

Diagnosis: Borer Infestation

• Insects bore into trunk → swelling, sap
• Extensive for small tree = poor prognosis

Treatment Attempt

1. Spray wound with Merit (imidacloprid) to kill borers inside
2. Fertilize: 10-10-10 at 1 lb/inch DBH
3. Water during drought

Outcome

Survival uncertain. Next spring leaf-out tells the story.
