Planting bee balm
Plant divisions or nursery starts in spring or early fall. Seed can be sown in spring but often takes a year to reach blooming size.
Planting details
- Spacing: 18 to 24 inches for airflow between plants
- Choose mildew-resistant cultivars in humid climates
- Divide clumps every 3 years to keep the centers vigorous
Growing requirements
Bee balm likes full sun to light shade and moist, rich soil. Air circulation is the main defense against its one real weakness, powdery mildew, so give plants room rather than packing them in.
Harvesting and care
Deadhead to stretch the bloom period, and thin or divide clumps when the centers thin out. In humid regions, water at the base and avoid crowding.
Common mistakes
- Crowding plants, which nearly guarantees powdery mildew by midsummer
- Letting the soil dry out completely, which stresses plants and worsens mildew
- Planting in deep shade, which produces floppy stems and few blooms
Companion plants
Tall phlox, coneflowers, and native grasses match bee balm's height and moisture needs. Keep it out of the driest beds, where it struggles and mildews faster.
