Rescuing Overpotted Corn Plants and a Struggling Dieffenbachia

Fixing a Repotting Mistake with Dracaena massangeana

Jen combined two large corn plants (each with 3 canes, one mushy) into a 16-inch pot with Miracle-Gro. She asks about shock, Superthrive, and a dying dieffenbachia.

Corn Plants

• Danger: Excess soil holds water, causing root rot. Top ⅓ must dry within 2 weeks.
• Fix: Remove all added soil down to original root balls. Ensure pot has drainage.
• Light: Bright indirect helps soil dry.
• Superthrive: Not needed; proper watering is key.

Dieffenbachia

Suffering from low light and/or wet soil. Move to brighter spot, let soil dry more between waterings.
