Did he ruin his mom's lilacs?
About three years ago, my husband was trying to be nice to his mom and did a bunch of yard work for her. Unfortunaly he took it upon himself to prune back her lilac bushes, and he pruned them way back. Here it is three years later and the lilac gets beautiful green foliage, but it is still not blooming. Does anybody know if they are salvageable, or do we need to invest in getting new bushes all together?
