Overwatering and Root Rot
Why: Excess moisture causes root decay, which spreads upward into the stems.
Signs to check: Stem base is soft and discolored, soil is constantly wet, foul smell may be present.
Bacterial Soft Rot
Why: Bacteria enter through wounds or damaged tissue, causing rapid tissue breakdown.
Signs to check: Stems collapse suddenly, mushy areas may be slimy, spreads quickly.
Cold Damage
Why: Freezing temperatures cause cell walls to burst, resulting in mushy, water-soaked tissue.
Signs to check: Damage appeared after cold exposure, affected areas are translucent and water-soaked.
