Hi, I have several Rhipsalis plants and one of them is quite old. I made the mistake of putting outside where it got sun from 11 am to 1 pm. Bad move. I ended up cutting off all the sunburned parts. It is growing inside now, and I'm going to put it undercover this spring but I would like to even out the growth. Some of the plant is putting up strings that are 3 feet long. But only on one side. How do I stimulate growth on the other side? Also, Can epiphyllums be pruned back to make them smaller? Thanks for your time and attention.
