- I have a similar situation (20 year old lilac bush, 15 feet tall, north
- side of the house). From talking to local nursery people, I've learned
- that drastic pruning of lilacs will most likely interrupt the next year's
- blooms. Winter is a good time for the 1/3 cut. If you're just trimming
- the bush for shaping, try to cut right after the blooms are done--you stand
- the best chance of blooms next year.
-
- The question I didn't answer (and need to find out, too) is deciding what
- to cut. Should all of the suckers be cut to the ground? Should the main
- (oldest) branches be cut back to let the suckers take over? Does the plant
- need special attention after cutting back 1/3 (like special nutrients)?
