Avoid draughts, heat from radiators or other sources. Care for your Christmas Cactus - keep it cool. Christmas cactus can adapt to low light, more abundant blooms are produced on plants that have been exposed to high light intensity. Keep your plants in a sunny location indoors. Plants can be moved outdoors in summer, but care for them in a shady or semi-shady location. Too much direct sunlight can burn the leaves. When it's time to bring the plants back inside in the Autumn, slowly adjust the plants to life indoors by gradually increasing the number of hours they spend indoors each day. 
Well-drained soil is a must in proper care for Christmas cactus. Use a commercially packaged potting mix for succulent plants or mix your own by combining two parts plain potting soil with one part clean sand or vermiculite. Pruning Christmas cactus after blooming will encourage the plant to branch out. Remove a few sections of each stem by pinching them off with your fingers or cutting with a sharp knife. These sections can be rooted easily in almost any compost. Christmas cactus will bloom if given long uninterrupted dark periods. Begin the dark treatments in about mid-October to have plants in full bloom by the holidays. Christmas cactus will also bloom if they are subjected to cool temperatures of about 50 to 55F at night. The main pest is mealy bug - a small white wooly bug that enjoys sucking the sap out of the plant. Back to A-Z of Houseplants |
