Light. Many crotons grow best in full sun, though many tolerate or prefer light shade. Bright light brings out the strongest color, but too much can fade it.
Water. Water regularly but not excessively, especially in hot, humid weather. Wilting new leaves are the sign it needs water.
Soil and feeding. In containers, use a quality, well-drained mix such as Potting Soil.
Size. Grows to about 3–4 ft. In beds, space plants 2–3 ft apart.
Problems to watch. Mealybugs, scale, spider mites and thrips occasionally attack; treat with Insecticidal Soap. Fungal problems can also occur.
Good to know. Frost or freeze damages the leaves, but crotons recover quickly. The leaves are poisonous and irritating if chewed, so keep children and pets away. The sap can stain.
