How to Grow
Plant Monarda didyma ‘T & M Superb Mixed’ in the spring or fall, selecting a location that receives full sun to partial afternoon shade. This perennial thrives in rich, humusy, moisture-retentive soils, making it an excellent choice for rain gardens or areas near streams. While it prefers well-drained sites, this Bee balm shows tolerance for heavier clay soils, though you must ensure the soil is never allowed to aggressively dry out, especially during peak summer heat.
Watering is critical for healthy Monarda, as the soil should remain consistently medium to wet. Allowing the plant to become severely stressed by drought dramatically increases its susceptibility to fungal issues. Fertilization is generally unnecessary if the soil is rich; focus instead on improving organic matter content at planting time.
Maintenance primarily revolves around managing its vigorous habit and preventing disease. Providing plants with excellent air circulation is key to combating powdery mildew. To encourage extended blooming well into summer, deadhead spent flower heads promptly.
To maintain vigor and prevent monoculture dominance, plan to divide the spreading rhizomes every three to four years. This division process helps control the spread of the Monarda didyma ‘T & M Superb Mixed’ colonies and rejuvenates the clumps for the following season.
Landscape Uses
Bee balm is a superstar for bringing vertical structure and intense color to mixed borders, cottage gardens, and naturalized settings. The ‘T & M Superb Mixed’ variety excels along pond edges or streamsides where its medium to wet water needs are naturally met. Use these colorful spikes to add dynamic texture near the border front where their foliage can still provide some screening.
For wildlife gardening enthusiasts, planting Monarda didyma ‘T & M Superb Mixed’ en masse creates an undeniable beacon for hummingbirds and butterflies. They integrate beautifully into native plant gardens, pairing well with other moisture-loving perennials such as Astilbe, Joe-Pye Weed, or tall ornamental grasses. This plant’s ability to tolerate clay soil also makes it a robust filler for difficult transition areas in the landscape.
These flowers are also excellent for fresh cut flower arrangements, adding that characteristic bold, whorled shape to indoor displays. The colorful blend of red, pink, and white ensures contrast and depth when mixed with blue or yellow summer bloomers.

Potential Problems
Powdery mildew represents the most common aesthetic issue for Bee balm, especially when plants are crowded, leading to poor air circulation. If the soil is allowed to dry out, the stressed plants become increasingly susceptible to this fungal disease, as well as rust. To actively manage this, ensure you provide excellent spacing when planting Monarda didyma ‘T & M Superb Mixed’. Prompt deadheading after flowering encourages fresh, cleaner growth, and regular division prevents overcrowding that exacerbates mildew issues. Deer and rabbits tend to avoid this aromatic plant.

Companion Planting
Given the high moisture needs and height of Monarda didyma ‘T & M Superb Mixed’, select companions that also appreciate consistent moisture and can complement the vertical structure. Plants like Japanese Iris or Siberian Iris provide contrasting leaf textures near the base. For bold, late-season color that shares similar cultural needs, try pairing this Bee balm with Rodgersia or Joe-Pye Weed (Eutrochium). Avoid planting too closely around the base, as good air movement is essential to protect the Monarda foliage.
Propagation Tips
Propagation is successfully achieved through division, which should be planned every three to four years for optimal plant health. In early spring before new growth significantly emerges, carefully excavate the clump of Monarda didyma ‘T & M Superb Mixed’ and separate sections, ensuring each new piece has a healthy root system attached. Alternatively, the plant will readily self-seed; deadheading spent flowers prevents unwanted seedlings but leaving a few heads standing will naturally naturalize the area.
