After extensive pruning of black cankers, soil replacement, and Bordeaux/fungicide treatment, new cankers still appear on a weeping willow. Conventional chemicals often fail against systemic canker fungi. Atomic Grow, an organic foliar and soil drench product, stimulates the tree's natural defenses, cleanses vascular tissue, and can suppress fungal progression.
Healthy, vigorous willows often outgrow canker infections. Focus on building tree vitality.
