Wife has bought two standard lilacs from QVC. After a month, one has a
different type of leaf growing from above the graft, looks very much like
privet. Is it possible that rootstock is privet? I have cut off the
offending shoot and rubbed out some small buds way down the stem. Is this
going to be a regular problem?

Surely the growth is of the scion and not the stock if it is above the
graft.

I would like to attach a n additional question:
I have a forest of suckers from below the graft of a lilac. No amount of
clearing up seems to curb them. Does it make sense to try and control them
with glyphosate, or will I wreak irreparable damage on the tree?
