- Don't do it! This is *wrong*. Lilac blooms on old wood; if you prune now you
- won't see any flowers until 1994.
-
- Prune after the flowering season. When you prune, get rid of the oldest wood,
- or in any case cut it down to about 6' (new branches will emerge from it, if
- it's not too old). Your goal is to replace the oldest wood with younger, more
- vigorous growth. You might consider cutting off the youngest shoots as well,
- to tidy up the bush and concentrate its energy in shoots closer to flowering
- age.
