Pruning lilacs

Asked May 20, 2018, 4:35 PM EDT

We have a row of lilac bushes with foliage and blooms 6 feet or higher between our house and our neighbors. The lower stems and branches below are bare. Can we severely prune the bushes back to the bare branches to control the bushes size and try to encourage growth on the lower branches? Or will it harm or kil the lilacs?
