|Prune your lilacs after the flowers fade. You can prune your lilacs back as much as one-third without harm but taking the stems back by just a few inches is also acceptible. Lilacs spend the summer months developing new stems and leaves - and making flower buds for next year's floral display. That's why it's important to prune them immediately after flowering - to give them lots of time to develop new growth. Enjoy your lilacs!
