Croton Gold Star codiaeum plants are bright tropical shrubs that grow for years under the proper conditions. To care for them, you need a suitable location, well-draining soil, fertilizer and pesticide.
Choose a location
Select a location that gets at least 6 to 8 hours of direct sunlight a day. With sufficient light, the plants grow up to 6 feet high and 3 feet wide. Croton plants thrive in containers as well, though you may have to re-pot frequently, as they grow quickly. They grow best in temperatures of 60 to 85 degrees Fahrenheit and can survive in temperatures as low as 40 F, but they should be covered in a frost.
Water and fertilize the plants
Croton plants need frequent watering. Plants in containers should be watered daily. Those in the soil should be watered every other day. However, in hot weather, they may need watering twice daily. To keep the leaves healthy and bright, mist the plants with spray from a bottle during the heat of summer. Feed them with standard liquid fertilizer every few months.
Protect the plants from pests
Sometimes mealybugs attack croton plants. They appear as white masses of cotton. Other pests that attack croton plants are mites and thrips. Such pests can be eliminated with pesticides manufactured for tropical plants. Read the pesticide instructions carefully, and do not over-spray.
