When is the best time to divide bee balm?
Bee balm (Monarda species) spreads rapidly via underground stems or rhizomes. In addition, the center of the plant often dies out within a few years. To control their spread and rejuvenate plants, it’s advisable to dig and divide bee balms every 2 to 3 years. Early spring is the best time to dig and divide bee balms. Dig up the plants as soon as new growth appears in spring. Divide the clump into sections with a sharp knife. Each section should have several shoots and a good root system. Immediately replant the divisions.
