Lilacs Won’t Bloom

Anonymous added on June 15, 2015 | Answered

Second year lilac tree/bush was planted and had lots of beautiful flowers. Hubby decided to cut it back in the fall and ever since, no flowers. It is now about 10 years old. Growing like crazy but no flowers. Did he ruin it completely?
