Bee balm is a perennial herb that grows vibrantly and prolifically in many home herb gardens. Because bee balm can grow quickly, gardeners often find themselves with clumps of bee balm that grow too large for a growing area. When this occurs, you have two options. Either divide the bee balm and replant parts of the plant elsewhere, or transplant the entire plant to an area that will better fit the herb. Transplant bee balm at the end of the growing season.
Difficulty: Moderately Easy
Prune back the bee balm in the autumn. Remove all branches to the point where they connect with the main stem of the plant.
Dig up the bee balm plant carefully with the shovel. Do not disturb the roots of the plant as you remove it. This is the time to divide your bee balm, if you desire. Insert the shovel through the center of the root system and cut the roots in halves or thirds.
Prepare a new planting area for the bee balm in full sun or partial shade (whether you divided it or not). Dig a hole for the bee balm so it is at the same depth as it was previously.
Place the bee balm plant into the prepared hole and carefully fill the soil in around the plant. Firm the soil down gently with your hands to finish transplanting the bee balm.
Water the newly transplanted bee balm generously immediately after you transplant it. Continue to provide water to ensure the plant does not dry out until you see new growth occurring on the plant.
