Water: Keep the soil evenly moist while your plant is blooming, misting it frequently.
Light: Place the cactus in an east-facing window for moderate light and some direct sun.
Tips: Repot your cactus each year after flowering. Maintain an optimal climate of 65 degrees.
About six to eight weeks before you want the plant to rebloom, you should allow the plant to begin its dormancy cycle by cutting back on Christmas cactus moisture and reducing both light and temperature. Simply cut back the watering and make sure the plant receives 12-14 hours of darkness and average temperatures around 50-55 F. (10-12 C.). Also, keep the Christmas cactus away from drafty areas.
