Troubleshooting
Salad Burnet problems — and how to fix them
Salad Burnet (Sanguisorba minor) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bitter, tough leaves
Old foliage and any growth after flowering turns bitter and fibrous. Harvest young central leaves and cut back flowering stems to force fresh, tender regrowth.
Aggressive self-seeding
Left to flower, it scatters seed and colonises beds. Deadhead the button flower heads before seed sets if you want to keep it contained.
Root rot in wet soil
Heavy, waterlogged ground rots the taproot and yellows the rosette. Plant in gritty, free-draining soil and avoid overwatering.
Powdery mildew in still air
Crowded plants in humid, stagnant spots can develop powdery mildew on leaves. Thin clumps and improve airflow to keep foliage dry.
