The trick to take care of a Croton plant is to provide steady warmth. A well-grown Croton plant keeps its leaves down to the soil level. Even Croton plants outdoors drop leaves after a cold night. Croton plants also need sun to maintain their vibrant leaf colors.
When caring for a croton plant indoors, low humidity can make the plant particularly susceptible to spider mites. Mist your plants daily to help avoid an infestation.Dr. Doom's "Go Green Spider Mite Knock Out "is a great product, that can be used for prevention.
Crotons can be brought outdoors in warm weather, as long as they are properly acclimated to the light and temperature conditions.
