Dealing with a Foul-Smelling Corn Plant (Dracaena fragrans): Causes and Solutions

Immediate Action: Return the Plant

A healthy Corn Plant (Massangeana Cane) should have no odor. A strong mildew smell indicates something is wrong in the soil—possibly fungus, bacterial decay, or even contamination (e.g., urine). The safest solution is to return it to the seller.

If You Must Keep It

1. Add horticultural lime to the soil to neutralize acidity.
2. Flush the pot repeatedly with clear water (filtered or distilled if tap water is hard).
3. Allow the top quarter of the soil to dry before watering again.
4. Monitor for recurring odor or decline.

Prevention

Always inspect plants before purchase. Avoid pots with sour smells, mushy stems, or fungus gnats. Use well-draining soil and water only when the top soil is dry.
