Lilac Pruning

Asked June 26, 2018, 10:46 PM EDT

Is it too late to prune my lilacs (in the Chaska, MN area). They have bloomed and gone, and new growth is coming where the old had been.

Carver County Minnesota

If you prune now, few or no flowers may be present next spring.

However, if renewal pruning is what you have in mind (cutting some of the oldest stems to the ground), stems that remain will flower if they are old enough to bloom.

Shearing or heading back will have a greater negative effect on next year's bloom.
