Maintenance
Cut it back hard, to a few inches, after flowering, and it will produce a fresh mound of clean foliage. That cut also serves the more important purpose of removing seed, because lemon balm self-sows enthusiastically and volunteers turn up across a garden within a couple of seasons. If you want to be certain it stays contained, grow it in a pot.
