MaintenanceThere are many different ways to prune a Lilac. The most drastic is to cut them down to the ground. Using this method I have had ones sucker back and regrow while others that didn't make. You can cut out the old stems and let the new suckers fill in thinning them to the desired amount. On many old plants we have removed all the suckers and left a few of the old stalks. Pruning them up to bare base stems, turning the plant into a small tree. Width can be controlled by pruning them back 1-2 or more nodes. Drastic pruning may delay flowering a few years. Since Lilacs bloom on next season’s wood, prune after they are done blooming
Propagationdivision of suckers, softwood cuttings
