What to prune in spring — experts reveal how to get a lush, full garden

Real HomesSarah Warner, greenhouse manager at the Case Western Reserve University Farm, shared her recommendation on how to prune lilacs in the spring. “You can deadhead after the flower is spent and turned brown. Prune it at the base and will conserve energy for the tree. If the lilac is too tall, take out the largest branches and cut those at the base,” she said.
