A couple of months ago I relocated one of my camellias to another location. It's medium size. When digging up the rootball, I lost part of the tap root. It seemed fine for a week, then began wilting, now only a few leaves left. Is there anything I can do to revive it? I moved several others at the same time in the same general area and they look wonderful! Would appreciate any advice before I cut it down or dig it up.
