Control light and Christmas cactus will bloom

December 21 marks the winter solstice in the Northern Hemisphere, with the shortest day and longest night of the year. Christmas cacti, poinsettias, kalanchoes, and chrysanthemums are popular plants given as holiday gifts due to their flowering timing. The plant response to day length is called “photoperiodism,” with some flowers as day length gets shorter, while others flower as it gets longer. Some plants are neutral, where day length doesn’t directly influence flowering. Christmas cacti, native to Brazil, are popular houseplants with a wide variety of colors and can last seven to eight weeks if kept at 68 degrees Fahrenheit.

Clients often call the University of Georgia Cooperative Extension office disappointed that their Christmas cacti or other short-day houseplants failed to bloom. They are surprised to learn that keeping these plants indoors can disrupt their normal cycle of daylight exposure. To mimic normal daylight exposure with shorter days, clients can place them in a room with natural light exposure near a window, ensuring artificial lights stay off at night. Another option is keeping them outdoors in the fall and bringing them indoors just before freezing temperatures, usually around the end of October in the Atlanta area. By this time, short-day plants are programmed to start forming flowers during the upcoming holidays. The author recalls their grandfather keeping a Christmas cactus on his porch all summer and bringing it indoors just before freezing, bringing him many years of Christmas joy.

Do you water a Christmas cactus from the top or bottom?

Christmas cacti are a unique plant that doesn’t shed leaves like poinsettias or other houseplants. Instead, they use photosynthesis within green stem segments called phylloclades. To promote branching terminals and root new plants, pinch back the stems in early June. Good flower bud production on Christmas cacti during the fall requires temperature regulation and photoperiod control. Fourteen hours or more of continuous darkness each night is required before flower bud set, which should start around the middle of September and continue for at least six weeks. Buds typically appear in about four weeks.

Christmas cacti tolerate dry, slightly underwatered conditions during spring and summer, but should not be waterlogged, especially during winter nights. After bud set in the fall, maintain even soil moisture to prevent flower buds from falling off. Fertilize plants monthly using a one-half strength liquid fertilizer, such as 20-20-20 with trace elements, and stop fertilization during late summer for greater flower bud production in the fall.
