Dieffenbachia Getting Top-Heavy: Water More, Prune for Bushiness

Your dieffenbachia (dumb cane) is healthy but under-watered for its size. As roots fill the pot, they need more frequent watering—not a larger pot yet.

Watering

Increase to twice-weekly soaks. If that's still not enough, then move up one pot size (max 2 inches wider).

Pruning for Lower Leaves

New growth only appears at stem tips. To get leaves lower down, prune stems back to where you want new foliage. Cuttings root easily in water.

Fertilizing

Continue dilute Miracle-Gro with each watering—it's appropriate.
