MaintenanceSince Lilacs bloom on next season’s wood, prune after they are done blooming. There are many different ways to prune a Lilac. The most drastic is to cut them down to the ground. I have had ones sucker back and regrow while others that didn't make it using this method. 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. Drastic pruning may delay flowering a few years
Propagationdividing off a sucker, soft softwood cuttings, grafting
Cultivar OriginIsabella Preston, Central Experimental Farm, Ottawa Ontario Canada, 1936.
