how long can i keep cactus outside
Take It Outside. In springtime, you can take your Christmas cactus outside in its pot as long as day and nighttime temperatures stay above 50 degrees Fahrenheit. But unlike desert cactuses, the Christmas cactus wonât tolerate the intense full summer sun. Full direct sun will give the plant severe sunburn.he Christmas cactus (Schlumbergera bridgesii) is a native of Brazil but is grown widely as a winter-flowering houseplant. In nature, it grows as an epiphyte in shady tropical rain forests.
