Saving a Corn Plant from Root Rot After Repotting

Saving a Corn Plant from Root Rot After Repotting

A Dracaena fragrans (corn plant) that was thriving in its nursery pot often declines rapidly after being moved into a decorative container without drainage. The symptoms—brown, dying leaves—are classic root rot.

Why It Happens

Without a drain hole, water accumulates at the bottom of the new pot. The roots sit in stagnant water, suffocate, and rot. A pot that's too large compounds the problem because the excess soil stays wet far too long.

Rescue Steps

1. Move the plant to a pot with a drain hole and a diameter no more than 2 inches larger than the original root ball.
2. Use a well‑draining mix (2 parts potting soil : 1 part perlite).
3. Water thoroughly, then empty the drainage tray after 30 minutes. Never let the plant sit in water.
4. Allow the top 2–3 inches of soil to dry before watering again.

Timing Matters

Repot only during active growth (April 1 – July 30). In fall and winter, shorter days slow root growth, making rot more likely.

With proper drainage and a disciplined watering schedule, your corn plant can recover and resume healthy growth.
