Hello, I’m Amanda McNulty with Clemson Extension and Making It Grow. If you want more challenges to have the perfect Thanksgiving or Christmas holiday, you can try to provide the correct light and temperature requirements so your Thanksgiving and Christmas cacti bloom. They need a certain amount of darkness and cooler night temperatures, and higher humidity than many parts of your house. The humidity isn’t hard, put them in bright indirect sun on rocks in a water-filled dish. If you put them in a closet for darkness but open the door even one time to get a coat or such and let in light, you are up the creek. It’s easier to just put a box over them, no one is going to keep their winter coat under a box! Hybrid Holiday cacti are the ones most available and they aren’t so persnickety.
Have a spare box? Save it for your holiday cacti.
