101 Ideas: How to care for a Christmas cactus
Mount Shasta Herald
Christmas cactus is a long-lived tropical plant that flowers for about a month in winter. Not the drought-tolerant desert plant that its name suggests, Christmas cactus is native to Brazil, often rooting in collected leaves and other debris in the crotches of trees.
This popular houseplant doesn't tolerate having wet feet, but it also doesn't want to be bone-dry. Use potting soil that offers excellent drainage, water when the top inch of the soil is dry and avoid overwatering; the plant is susceptible to root rot.
