Lucky Bamboo (Dracaena sanderiana) Stem Rot: Root Rot Diagnosis & Rescue

Sudden stem death and leaf drop in a mature lucky bamboo (often grown in water or soil) usually signals root rot from overwatering or stagnant conditions.

Diagnose & Treat

1. Unpot gently: Remove plant, rinse roots. Healthy roots = white/firm. Rotted = dark, mushy, foul-smelling.
2. If partial rot: Trim all dead roots + ½″ into healthy tissue. Repot in fresh, well-draining mix in a pot 1 size smaller. Place in bright indirect light. Water barely—just enough to prevent wilting. Resume normal care only after new growth appears.
3. If >50% roots rotted: Propagate healthy top sections. Cut 4–6″ stems below nodes, place in clean water or moist perlite until roots form.
4. If roots look healthy: Inspect for pests (mealybugs, spider mites). Treat accordingly.

Prevention

• Water-grown: Change water weekly; use distilled/rain water; rinse container.
• Soil-grown: Allow top 1–2″ to dry between waterings. Ensure drainage.
• Light: Bright indirect—no direct sun.
• Fertilizer: Very dilute (¼ strength) monthly in growing season only.

Act fast—root rot spreads rapidly. Salvage healthy portions even if the main plant is lost.
