Bee balm is available to plant in the spring and fall. Plant them as soon as they arrive in well-drained soil that has been amended with organic matter. If you cannot plant them at once in permanent positions, shallowly heel them into a temporary position and keep them well-watered until transplanting.
Light: Bee balm does best in full sun. Though it will grow in part shade, it tends to stretch and become leggy over time.
Soil: Bee balm does best in evenly moist soil rich in organic matter. It can tolerate lighter soil, but richer soil will encourage taller, stronger specimens. Boggy conditions are not tolerated, nor are soils that are allowed to dry out for long periods of time.
Spacing: Plants should be spaced 18-24 inches apart.
Bee balm is in the mint family, and absolutely lives up to the family name. It will intensively spread over a season via a mat of underground stems (stolons), but can be kept under control by regular digging and dividing.
Planting: Plant bee balm in the spring or early fall. Either time of year works well; however, when fall-planting Bee Balm, it's best to trim back the foliage to encourage the plant to focus its energy towards the roots.
