|Lilac bushes develop buds during the summer months for the following spring's bloom. Prune after this season's flowers fade by cutting back the stems that produced flowers. Cut back to a pair of leaves and new flowering shoots will develop. Annual late-spring trimming will keep your lilac compact in size and enable it to produce new shoots for the following year's bloom.
