Sow and Plant
Start with purchased plants, set out in spring. Many selected cultivars are resistant to powdery mildew, a common problem with this species. 12" (30 cm) each way (minimum) is a good spacing for an initial planting of 3 plants. Monarda is a slight spreader, but not invasive like mint. Over time, a happy plant will form a mount 4 feet (120 cm) high and wide.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.
Pastel flower colours look especially cooling in partial shade. Leaves are excellent for tea.
Harvest stems to dry for tea in early summer, before the plants bloom. The plants will regrow after cutting, then bloom.
Moving clumps every few years may help limit problems with powdery mildew.
