Overwatering Stem Rot on crassula
What's Happening
Crassula ovata (Jade Plant) possesses a woody, tree-like stem structure with succulent leaves adapted to seasonal drought cycles. Overwatering causes water to accumulate in the pithy stem tissue and root crown, creating anaerobic conditions that promote bacterial soft rot (Erwinia spp.). Unlike leaf succulents that show rot in foliage first, Crassula typically exhibits stem softening at the base where the vascular system becomes compromised, potentially killing decades-old specimens.
How to Fix It
- 1
Immediate action: Stop all watering and move to bright, warm location with good airflow
- 2
Stem inspection: Gently squeeze lower stem—healthy tissue is firm like wood; soft/mushy areas indicate rot
- 3
Prune above rot line: Use sterilized pruning shears to cut 2-3 inches above the affected area into healthy firm tissue
- 4
Callus thoroughly: Allow cutting to dry for 7-10 days in shade until cut surface forms hard, dry cork layer
- 5
Root in dry medium: Place cutting in dry succulent mix or coarse perlite without watering; roots emerge in 3-6 weeks; water only when new growth appears
What You'll Need
How to Prevent It
Implement 3-4 week minimum between waterings for established plants. Use shallow pots no more than 2 inches larger than root ball to prevent excess soil moisture. Position in bright direct light (south-facing window) to maximize transpiration. Reduce watering by 50% in winter when growth slows and temperatures drop.
