The Spruce - How to Grow and Care for Bee Balm⚓︎
Light, yearly pruning can be done if you wish to keep this plant bushy. Simply pinch off the tips of the stems in the spring. Cut the bee balm down to a few inches in the fall to promote new growth in the spring.
Since these plants are prolific bloomers, continually cut and deadhead the flowers to encourage the plant to produce more.
