Cedar top cutting for potting?
I was gifted with a lovely potted western red cedar. I'd like to keep it on my apartment balcony, and keep it compact. Problem is, it's already 6 feet tall, a bit bigger than I want for the space. I'm wondering if I can cut it and expect it to survive. I've read that branch cuttings are often successful, but I am wondering about the potential viability of a top cutting. What I am considering is to cut off the bottom three feet or so and discard it, put rooting hormone on the new base-- which would be about an inch in diameter-- and re-pot that top cutting, so I'd have a three foot tree. Could this work? Or would I basically have a Christmas tree that would die in a short time?
Alternately, if I decide to try to keep it at its present size, can I expect success in limiting its growth by periodic root trimming/keeping it potbound like a houseplant?
I am a newbie to growing trees, so please respond gently! :-) Thanks.
