Growing Bee Balm in Zone 4A

Bee balm (Monarda) is a native perennial that puts on a spectacular summer show while feeding hummingbirds, bees, and butterflies all season.

Zone 4A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Good air circulation prevents powdery mildew — common problem
• Choose mildew-resistant varieties (Jacob Cline, Raspberry Wine)
• Deadhead spent blooms to extend flowering period
• Leaves make a spicy, bergamot-like tea similar to Earl Grey

Companion Planting
