Bee Balm Seeds,
Spotted

Start seeds indoors 8-10 weeks before the last frost, or direct sow after the last frost. It is hardy in USDA zones 4-9, making it suitable for a wide range of climates. In warmer regions, seeds can be sown in the fall and left on the soil surface over winter; they come up in late winter or early spring and, needing 100-120 days to maturity, bloom from midsummer on, with the fullest bloom often coming the second year​.

To start Spotted bee balm from seeds, simply press the seeds onto the soil surface without covering them, as they need light to germinate. Keep the soil moist until germination occurs, usually within 14-21 days. Once the seedlings have a few sets of true leaves, they can be transplanted into their permanent location, spaced about 12 inches apart​.

Water the plants regularly, especially during dry periods, but be careful not to overwater, as the plant prefers drier conditions. Mulching around the base can help retain soil moisture and suppress weeds. Spotted bee balm can spread by self-seeding, so monitor its growth if you prefer a more controlled garden space​.

Seeds usually mature 1-3 weeks after flowers bloom. To test, bend the spent head into a bag and tap. If the seeds are brown, they are ready. Spread them out and allow them to dry for 2-3 days. Store in an airtight container in a cool, dry, dark place.
