I posted this earlier in another thread, with no response. Perhaps someone
could help? TIA.

Our lilac bush has been planted for
quite a few years (7 or 8) and this is the first year of prolific bloom. I
do have questions, though. There's a heavy undergrowth of new shoots -
should these be removed at (or below) ground level, or even removed at all
because they will replace old growth - and when (and if) should old growth
be removed to encourage flowering?
