These plants tolerate the highest temperatures and light extremes experienced in growing houseplants, but need 40 to 80 percent humidity. Crotons perform well in a sunny location and with a potting mix kept evenly moist. Use a potting mix with good drainage. New plants may be started with four to six inch long stem cuttings. Remove the bottom leaves and place the stem cutting directly into potting mix, or plant them after roots have begun to form in a glass of water.
Crotons occasionally attract pests such as mealybugs, spider mites and scale.
