We have a lovely small split leaf Japanese Maple, which is fully
leafed out at about 3/4 of it's circumference. The last 1/4 of the
circumference is fairly bare. What we would like to do is to force
the tree to fill out completely. Is there a way to force the tree to
start filling in this bare spot: for instance, can we attempt a graft
from another part of the tree in the bare area?
Thanks in advance
