8 months, 1 week ago Deadheading monarda? Q&A If I deadhead my bee balm will it rebloom? - Pat - Comments Dennis Patton 8 months, 1 week ago Deadheading often will result in another round of blooms. With the cooler weather and rains the plants will be more actively growing which means more flowers. Bee Balm or Monarda also gets a little ratty looking late in the summer so a trim will clean it up. Dennis - Johnson County Extension Sign in with Facebook to comment.
