Repotting an 8-Year-Old Dieffenbachia: Downsize Pot, Refresh Soil

Vee's 8-year-old dieffenbachia in huge pot has cruddy soil with white mold, smells mildewy when watered, barely grows (12 inches).

Darlene: Repot into smaller pot (not much bigger than plant). Huge pot causes stagnation, mold, no growth. Use fresh soil + extra perlite (2:1). Repot in February, then fertilize monthly with Miracle-Gro. Waiting lets roots recover before fertilizing.
