Diagnosing Sudden Death in Mature Climbing Roses: Root Diseases and Soil Remediation

A 25-year-old climber that suddenly dies in midsummer likely has a root issue. Check the base for:

• Crown gall: Tumor-like growths on roots or crown from fungal infection; causes slow decline.
• Verticillium wilt: Soil-borne; leaves wilt from base upward as water uptake fails.

Residual moisture in canes can push weak growth after root death, creating a sudden-death appearance. Do not replant roses in the same soil without removing as much as possible to eliminate pathogens.
