I prune mine hard............about a foot from the ground. It comes back with a vengence. LOL
I had to relocate mine this spring as it was pretty close to some cement walls/footings that we dug out from our garage fire a year ago. I had hubby grub it out with the loader tractor........no way I was going to get those roots loose and dug out. I put it in a 20 inch pot (and had to stuff to get all those roots in there) for about a month, and planted it in its new home not too long ago. It's making shoots and leaves like nobody's business. You'd never guess it was moved.
