The croton "Red Ruiz" plant is a cultivar of Codiaeum. These plants are desirable for their colorful foliage, which can range from green to orange, yellow, red or variegated. The "Red Ruiz" is a variety noted for the brilliantly red shade of some of its leaves, which are usually mixed with bright green leaves. While some cultivars of croton can reach 12 feet in height, the "Red Ruiz" is usually grown as a houseplant.
Grow your croton in a container that has drainage holes and is filled with well-draining soil. Use a potting soil that is formulated for succulents and cacti, as these soils have the necessary amounts of sand included.
Light and Warmth
Set your plant in a location where it will receive full sun. The more sun the croton is exposed to, the brighter the leaf colors will be. Six hours of sun exposure is the minimum amount, but eight to 12 is even better. In addition, keep your Red Ruiz away from cold drafts or temperature extremes. Warm, consistent temperatures are ideal for this plant.
Water and Humidity
Keep the soil moist, but not soggy. Water when the top layer of soil dries out. These plants enjoy slightly damp soil, but standing water will rot their roots. Empty the catch-tray under the container as soon as the water stops draining. Crotons enjoy humid conditions, so for best results, place your pot on a tray of pebbles filled with water. Do not let the pot touch the water, but rest it on the pebbles. The water will evaporate and provide the plant with some humidity.
These shrubs can grow fairly quickly, so you will probably have to re-pot your croton once every two years. Note that these plants do not like change, and the process may cause the croton to drop its leaves. This is normal, and with time, the plant will recover.
