I recently bought a house with existing boxwood in the front yard. I'm not completely dissatisfied with it but I would like to know if it's possible bulk it up again. I have read a lot of information about thinning out boxwood to let it breathe and produce new growth, but what about the opposite? How do I bulk it up without doing serious surgery, or maybe my boxwood is just very old and needs to be retired?
Thanks for any help!
