Alocasia Root Rot: Early Signs + Step-by-Step Treatment

Root rot is the fastest way a healthy-looking Alocasia declines indoors—but it’s often recoverable if caught early.

Quick answer: Remove rotted roots, repot in airy mix, improve drainage, and reset watering based on soil dryness.

Early Signs of Root Rot in Alocasia

• Multiple yellow leaves at once
• Drooping despite wet soil
• Soil staying wet for too long
• Musty/sour smell
• Soft petioles or stem base

Confirm It: Root Inspection

1. Remove plant from pot gently.
2. Rinse roots to see structure clearly.
3. Healthy roots = firm, pale, crisp.
4. Rotten roots = brown/black, mushy, smelly.

Treatment Plan

Step 1: Trim damage

Use sterilized scissors to remove all mushy roots.

Step 2: Refresh media

Repot into chunky, oxygen-rich mix (potting base + bark + perlite/pumice).

Step 3: Use the right pot

Drainage holes are non-negotiable. Avoid oversized pots.

Step 4: Water correctly

Water thoroughly once after repot, then wait until top 1–2 inches are dry.

Step 5: Stabilize environment

Bright indirect light, warm temps, and moderate humidity.

What Not to Do

• Don’t keep watering on a fixed calendar
• Don’t fertilize heavily during recovery
• Don’t leave old compacted soil in place

Recovery Expectations

• First 7 days: stress may continue
• 2–4 weeks: decline should stop
• 4–8 weeks: new healthy growth is the key sign
