I have a large cedar hedge that in most parts is very full and dense, but due to excessive outward growth and lack of consistent pruning, there are sections that are very open and "woody", with the stump exposed and not a whole lot of branches for new growth.
I've read that with cedar trees, old wood will not put out new growth, and as such, I'm concerned that this section of the hedge will not fill in well, given the lack of existing growth in the area.
I was wondering, is it possible to graft new small branches to the stump? If so, which grafting technique would be the most effective here?
