[header] How to care for a christmas cactus [title] Give your christmas cactus bright but indirect light. [step] Keep the plant in a well-lit location (like near a window) away from direct sunlight-too much heat and light can stunt growth and burn the leaves. It should also be away from drafts, heat vents, fireplaces or other sources of hot air. 
[substeps] Move an indoors plant outdoors in summer to a shady location. It is best to keep in a normal house temperature range, about 65 to 75 ° f (18 to 20 ° c).
