Q.Hello, Can You Give Me Advice On How To Prune These Two Plants. I Have Had Them A Long Time And They Are Now Getting Too Big For
house. The first plant, the one outdoors is a night-blooming Cereus, I have had about 10 years. It stays outside in the summer. The second one I don’t know what it is, I bought it at Ikea and have had it almost 30 years. Can you tell me how to safely prune them, I don’t want to harm them but they are becoming too big for the house.

Prune, no more, than 1/3 of each plant at one time. With the Dracaena, cut back to your desired height. Preferably, one branch per week. This should be done during the active growing phase, which can be just about any time indoors.

The Night Blooming Cereus will prefer a summer pruning, as well, during the active growing season. They are, not at all, picky about pruning, but it is always best to follow the "1/3" rule.
