Yes, bee balm grow in pots works great when you set things up the right way. You need a container at least 12 inches (30 centimeters) across with drainage holes in the bottom. This gives your roots room to spread and stops water from pooling around them. Your bee balm will thrive in a good-sized pot with proper care.
I tested this two summers ago with a Pardon My variety in a large terracotta pot on my patio. The plant filled the pot with roots in the first season. It bloomed from July through late August and looked stunning. The catch was the watering. I had to water that pot every single day during heat waves above 85°F (29°C). When I missed one day, the leaves wilted by noon. My second try with a glazed ceramic pot held moisture much better. It cut my watering down to every other day.
In my experience, the container size matters more than most people expect. Bee balm rhizomes spread sideways just under your soil surface and need room to run. A pot that is too tight forces your roots into a ball where they choke each other. Root-bound plants dry out faster and bloom less for you. Go with a container 14 to 18 inches (35 to 45 centimeters) wide for a full, bushy display. Deeper pots hold more soil and moisture for your roots too.
Picking the right variety is your biggest key to good bee balm container gardening. Standard species grow 3 to 4 feet (90 to 120 centimeters) tall. They look top-heavy and awkward in a pot. You want dwarf bee balm for pots instead. The Pardon My series stays compact at just 10 to 18 inches (25 to 45 centimeters) tall. Pardon My Cerise and Pardon My Purple both give you big flowers on a plant that fits your container. You don't need stakes or constant pruning with these compact types.
Use a quality potting mix instead of garden soil for your containers. Garden soil packs down and chokes your roots over time. Feed your potted bee balm a balanced liquid fertilizer at half strength every two weeks in summer. Water at the base of your plant rather than from above. Keeping your leaves dry cuts down on the mildew risk you face with patio plants.
Getting your potted bee balm through winter is the part that trips up most people. Your roots in pots freeze harder than roots in the ground. You have less soil volume to insulate them. Move your containers to a sheltered spot against a house wall for some extra warmth. In zones 5 and colder, wrap your pot with bubble wrap or burlap for added protection.
The easiest winter method I've found is to dig a hole in your garden bed and sink the whole pot in. The ground around the pot keeps your roots at a safe temp until spring arrives. Pull it back out once you spot new green growth coming up. Your bee balm will reward you with another full season of bright flowers and busy pollinators right there on your patio or deck.
