Croton Care: Light, Water, Humidity, Temperature, and Toxicity

Memorial croton losing top leaves, growing new ones at base, with long stems. Owner asks about pruning, repotting, watering.

Repotting

Only repot if no drainage holes or root-bound stress (constant watering need, no new growth, roots circling). Use pot ≤2 inches larger. Unwrap a few bottom roots.

Light and Color

Moderate to bright light. Too much fades red/orange; too little prevents color development. High light = smaller leaves.

Watering

Keep moist (not wet) in active growth. Leaves stiff/upright = good. Falling/sloping = underwatered. Wilting = overwatered. Reduce in winter.

Temperature and Humidity

65–80°F ideal. Below 55°F = cold damage. Avoid drafts. High humidity: pebble tray or plant grouping.

Fertilizer and Toxicity

Balanced liquid at 1/3 strength, diluted 1:2 with distilled water, spring–autumn only. Never fertilize dry soil. Crotons are very poisonous—keep from children/pets. Sap irritates skin and stains.
