Hello, I pruned the lilacs pictured in early spring. These are mature shrubs that were about 6’ tall. They were starting to get sparse growth near the bottoms. They have been regularly sheered. I used the principle of thirds. Taking out some of the oldest canes and bringing the height down by a third, going forward for two to three years. As you can see one of the shrubs grew back normally, but the others have small leaves on the branches. This is a customer of mine. Please let me know if there is anything that I can do to help these lilacs survive and if they don’t how much is my pruning a factor. There were also birds nest evergreen shrubs in front of the lilac that did not make it over the winter. Thanks so much! Suzan
