How to Prune perennial phlox?

Garden phlox features tall, erect stems and fragrant, colorful flower clusters. Pruning should be done in early to late spring to encourage robust growth and flowering. Remove dead or weak stems at the base, trim back healthy stems by one-third to promote bushier growth, and thin crowded areas to enhance air circulation. Deadhead spent blooms to extend the flowering period. Pruning helps prevent mildew, encourages a neater appearance, and results in a healthier, more vigorous plant.
