Bee Balm is a perennial in Zones 3-9 which prefers full sun, but can tolerate partial shade.
The plant prefers consistently moist soil, although they can withstand the occasional drought or neglect.
Powdery mildew can be an issue, so leave adequate distance between plants (18 - 24") so they get proper air flow.
Deadheading blooms throughout the season can promote additional blooms.
Dividing your bee balm every 2-3 years keeps your plants looking fresh and perky.
Bee balm does tend to be a bit of a spreader as do other plants in the mint family. But it can be kept in check by pulling those odd runners once or twice a year.
