Bee Balm Seeds,
Lemon

Lemon bee balm can be started indoors, and set outside after the last frost or direct sown in the garden, two weeks before the last frost. This herb is hardy in USDA zones 2-11, making it adaptable to a wide range of environments. It grows quickly, and blooms throughout the summer.

To start lemon bee balm from seeds, scatter the seeds on the soil surface and lightly press them in, as they require light for germination. There is no need to cover them with soil. Thin seedlings to about 12 inches apart once they are large enough to handle. This spacing helps prevent overcrowding, which can reduce airflow and increase the risk of powdery mildew.

Lemon bee balm can tolerate poor soils but for better growth, you can add organic matter such as compost. The plant prefers well-draining soil to avoid root rot and other moisture-related issues. Prune the plants regularly to encourage bushier growth and more blooms, and deadhead spent flowers to extend the blooming season. Be mindful of its spreading nature; in optimal conditions, it can self-seed and become somewhat invasive​.

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.
