Phlox is pruned back AFTER spring blooming season to help maintain the form you prefer. This is generally late May (after flowering).You want to make sure there are no buds left to open before you begin this process. Using garden shears, cut back the plant by a third or half. Do this annual after each spring blooming season and you’ll get back on track.
