Fixing Dracaena Fragrans Leaf Curl, Root Rot, and Mold

Diagnosis: Classic Overwatering Syndrome

Your corn plant (Dracaena fragrans) shows all signs of chronic overwatering: leaf curl, minimal root growth, stagnant height, heavy soil, and surface mold. The 4-inch pot is actually appropriate – the problem is water management.

Immediate Rehabilitation Plan

1. Repot with a fast-draining mix: 1 part potting soil : 1 part perlite. Discard all old soil.
2. Clean the pot thoroughly with soap and 10% bleach solution; rinse well.
3. Replant at the same depth, firming new mix around roots.
4. Water once thoroughly, then empty the saucer after 1 hour – never let it sit in water.

New Watering Protocol (Critical)

• Test before every watering: Insert a bamboo skewer to near the pot bottom. Water ONLY when it comes out completely dry.
• This may mean watering every 2–4 weeks – Dracaenas prefer drought to soggy soil.
• Use distilled, rain, or filtered water – Dracaenas are sensitive to fluoride/chlorine in tap water, which causes brown tips.

Recovery Timeline

• Weeks 1–4: Root regeneration begins. No new top growth yet.
• Months 2–3: New roots establish; leaf curl gradually resolves as water uptake improves.
• Month 3+: New growth emerges from the cane tips.

Ongoing Care

Bright indirect light (east/west window), temperatures 65–80°F, monthly half-strength fertilizer in spring/summer. The mold will disappear once the soil surface stays dry between waterings.
