General Information
Lemon balm is a fragrant perennial herb that grows 2 to 3 feet tall and is loved by bees. To avoid aggressive spread, pinch-tip stems or grow in a container. Deer avoid lemon balm.
When to Plant
From seed: Sow seed in spring and early fall.
Transplants: Plant seedlings in spring.
Cuttings: Propagation by cuttings is possible. Roots well in water.
Planting
Plant 2 feet apart in full sun to part shade.
Soil Requirements
Prefers average, loamy soil that drains well.
Water Requirements
Keep plants evenly moist. Soil is too damp if it forms a clump.
Fertilizing
Amend soil with compost annually.
Pollination
Lemon balm is pollinated by bees and other flying insects.
Harvesting
Harvest before blooms open to control spread. Leaves can be used fresh or dried. Tie bundles of 5 to 7 sprigs and hang in a cool, dry place upside down so oils remain in leaves.
Storage
Once dry, strip leaves off stems and store leaves in glass jars to use until next year’s harvest.
