Hi,
There is a beech hedge at the bottom of my garden which has not been
properly maintained (doesn't belong to me). The hedge is some 20 odd feet
high and 90 ft long. The problem is that the growth is mostly in the top
half with the bottom being mainly trunks (some up to 6"). Yesterday I spent
trimming back the overhanging branches and whilst doing this I wondered if I
could "graft" some branches back onto the main trunks and re-establish
growth back toward the bottom? Would it be worth attempting and if so how
would I go about it?

regards,

David
