Fusarium Root and Crown Rot can show up on landscape plants, producing visible damage that ranges from leaf spots and discoloration to branch dieback depending on severity. Early detection gives you the best management options.
Start with sanitation: remove and dispose of affected material as you find it. Thin dense growth to improve air circulation, and redirect irrigation away from foliage. If the condition persists despite cultural adjustments, your local Extension office can help identify the pathogen and recommend targeted treatments.

Cultural Controls
- Use certified plants only.
- Resistant cultivars are available.
- Set new plants in well-drained soil (no standing water in winter) where red stele has not been known.
- Plant on beds raised 8 to 10 inches to improve drainage, or use drain furrows.
- In home gardens or small plantings, raise the bed 15 inches.
- Preplant soil solarization has been helpful in reducing populations of certain soilborne pathogens and weeds in western Oregon.
