About Lemon Balm

Lemon balm is a prolific mint-family herb with bright citrus fragrance. Used for teas, desserts, and calming remedies. Warning: it self-seeds aggressively — grow in containers to prevent garden takeover.

Grow in a container to control spreading. Harvest before flowering for best flavor. Cut back hard in midsummer to encourage fresh growth. Tolerates partial shade better than most herbs.
