FAQ

When should I prune lilac?
Prune right after flowering (June), removing spent flowers and shortening the longest stems by a third. Late pruning compromises next year's blooms.
Why isn't my lilac flowering?
Most common reasons: position too shady, wrong pruning, excess nitrogen or plant still young: lilacs bloom abundantly from the 4th-5th year.
