Plum Tree Decline: Bacterial Infection and a Systemic Cleanup Approach

Symptoms of Systemic Disease

Progressive limb dieback, sparse foliage, and poor fruit production over several years suggest a bacterial infection (e.g., bacterial canker, phytoplasma) or vascular disorder.

Rescue Strategy

Sanitation: Prune out dead wood, disinfecting tools between cuts (10% bleach solution).
Atomic Grow foliar drench: This organic product claims to cleanse phloem/xylem, open stomata, raise sugar levels, and boost natural defenses. Apply as a thorough spray to leaves, bark, and cambium.
Support recovery: Fertilize with balanced slow-release fertilizer, ensure proper watering, avoid stress.

Early, aggressive intervention offers the best chance to save a declining stone fruit tree.
