. Crotons thrive in warm, humid weather and should be watered frequently, but not excessively. New foliage will wilt when thirsty, and can be used as a watering guide. Plants located indoors will become dusty in time and should occasionally be taken outside into a shady location to be washed off. This will also help manage spider mites which are occasional pests.
Sunlight will maximize croton colors, but overexposure can cause fading and restrict proper foliage growth. For outdoor crotons, full or shifting sun is ideal. Acclimated indoor plants respond well to partial sun and will still provide continuous color.
To propagate a croton plant, use a stem cutting that is 3-4 inches long and has 3 to 5 leaves. Dip the cut end of the cutting in an off-the-shelf rooting hormone and plant them in a small pot. Keep the soil moist, but not over watered. Cuttings will root in less than a month if temperatures stay between 70°-80°F. Transplant your new croton plant when a new roots system has have been established and there is noticeable new growth. New foliage will begin green and will develop color with maturity.
