The lilac is a common reliable large shrub that may reach heights of 15 to 20 feet. As lilacs mature, the shaded lower portions of the shrubs usually lose their leaves, which result in large, overgrown specimens often leggy and unattractive. Old, neglected lilacs can be renewed or rejuvenated by two different pruning methods.
