Reviving a Sentimental Corn Plant: Root Rot Rescue

Assessing a 2-Year-Old Corn Plant in Decline

Loose bark on one cane indicates that stem is dead. Yellowing/browning leaves on remaining canes suggest root rot from overwatering—often triggered by repotting into too-large a pot.

Immediate Triage

1. Light check: Must be within 6 feet of unobstructed window, bright indirect light.
2. Soil check: If ever repotted, excess soil is likely holding moisture. Scrape away any soil added above original root ball.
3. Watering reset: Allow top 1/3 of soil to dry before watering thoroughly.

Removing the Dead Cane

Twist the dead cane gently while pulling straight up. It should release from the root mass. Collapse surrounding soil into the hole. This prevents rot spreading to healthy canes.

If Decline Continues: Emergency Repot

1. Unpot entire plant.
2. Remove all loose, wet soil.
3. Trim any dark, mushy roots 1" into healthy tissue.
4. Repot in smallest pot that fits roots (likely 12-14" for 3 canes).
5. Use well-draining mix with added perlite/bark.
6. Water lightly; place in bright indirect light.

Sentimental Value Consideration

If the plant is irreplaceable, consider taking stem cuttings from healthy canes as insurance. Root in water or moist perlite—corn plants propagate readily from cane sections.

Corn plants are tough. Correct the soil moisture environment, and they often rally beautifully, even after significant neglect.
