I have one in my backyard that's pretty big, about 4-5 ft tall. I'd
like to move it to the front yard where it will get more, and more
even, sunlight. Just wondering if anyone has done this successfully,
from what I have found on the internet they don't transplant well.

I understand the roots spread fairly shallow, but how deep should I dig
under for a bush this large?

Also, can I prune it back at the same time? Thanks.
