Sowing and Growing

Sow lemon balm seeds inside 6-8 weeks before the average last frost date for your region or once the soil can be worked. Germination will take about 2 weeks. Keep the soil moist, but not too wet. The plant will need more water as it grows. Lemon balm grows to about 2’ tall and wide. Lemon balm will go dormant through the winter season. Be sure not to overwater as this can lead to root rot.


Harvest lemon balm by picking off fresh leaves as needed or by gathering the cut stems into bunches and hanging them upside down to dry. Lemon balm’s flavor reaches its peak as the plant nears flowering. Dried leaves should be used within 6 months. Store in a cool, dry space. Use coconut oil or petroleum jelly to create your own lemon balm salve.
