As your flowers start to fade, you should deadhead bee balm just above the next flower bud to encourage further flowering. Once a stem has finished flowering, trim it back down to the ground or pinch it off.
Similarly one may ask, should you deadhead flowers?
Deadheading flowers is very simple. As plants fade out of bloom, pinch or cut off the flower stem below the spent flower and just above the first set of full, healthy leaves. Repeat with all the dead flowers on the plant. Sometimes it may be easier to deadhead plants by shearing them back entirely.
Bee balm begins blooming in early summer and continues through late summer and early fall. As the flowers begin to fade, snip off the blossoms before they form seed heads. This encourages the plants to produce more flowers. It also helps reduce reseeding in the flowerbeds.
