Can Norfolk Island Pines be pruned?
I have been growing a Norfolk Island Pine in my terrarium where it has been very happy. Right now it's about an inch and a half away from the top of the terrarium. I know it is still a way from actually hitting the top, but I'd love to keep it where it's doing so well and am wondering if I will be able to prune off the tops when the time comes that it gets too tall. I've had these plants as just houseplants, and haven't had great luck with them in normal conditions. My guess is a big No, but am hoping my instinct is wrong.
