Bacterial soft rot syndrome

Soft-rot bacteria can break down damaged, waterlogged, or chilled tissue rapidly.

Act soonPossible cause—not a diagnosis. Compare the visible signs, plant identity, and growing conditions before treating.

Signs you may notice

  • mushy tissue
  • rapid collapse
  • unpleasant odor

Safe first checks

  1. Isolate immediately and inspect where healthy firm tissue becomes soft.
  2. Separate the plant if the problem may spread.
  3. Remove only badly affected material with clean tools.
  4. Improve airflow and keep affected foliage dry while you compare the signs.

  • cold injury
  • phytophthora
  • ordinary decay

What to avoid

Do not assume every spot is infectious or use a disease-specific product without confirming the host and pattern.

Record and follow up

Photograph the same area in consistent light and note whether lesions enlarge, appear on new leaves, or stop after conditions improve.

Seek qualified local help when damage is severe, rapidly spreading, or may involve a regulated pest or disease.
