I bought a Korean lilac a few years ago and it has gown like topsy. It is now overgrown and I need to prune it back. When and how much? The blossoms are very fragrant each spring so I don't want to damage them.

The time to prune lilacs is right after they finish blooming. At this time, you can prune lightly to just remove the spent flowers or prune a bit harder to shape the shrub by pruning back to laterals or to where one branch joins another. Here are some tips from our website that discuss heavier pruning for overgrown lilacs: http://www.viette.com/v.php?pg=726
