Historical Background of Lemon Balm
Lemon balm, scientifically known as Melissa officinalis, has roots tracing back over 2,000 years. Native to the Mediterranean region, this aromatic herb has a long history of use in various cultures.
Ancient Greeks and Romans revered lemon balm for its calming properties. They incorporated it into wines and foods, appreciating its soothing effects.
The herb’s genus name, Melissa, derives from the Greek word for “honey bee.” This connection stems from the plant’s ability to attract bees, as noted by ancient writers like Pliny the Elder.
In the Temple of Artemis/Diana, lemon balm held sacred status. Beekeepers valued it for keeping honeybees content and well-nourished with nectar.
During the Middle Ages, lemon balm’s medicinal uses expanded. It became one of 165 plant species used for healing purposes. Ancient physicians like Dioscorides and Avicenna reported its effectiveness in calming nervous disorders.
By the 16th century, herbalists like John Gerard continued to document lemon balm’s benefits, particularly its appeal to bees and its restorative powers.
Throughout history, lemon balm has maintained its reputation as a versatile herb. Its aromatic qualities and perceived healing properties have ensured its continued cultivation and use across cultures.

Cultivation Tips for Lemon Balm
Lemon balm thrives in full sun to partial shade. It prefers well-drained, rich soil but can adapt to various conditions. Plant seeds or seedlings after the last frost, spacing them 18-24 inches apart.
Water regularly to keep the soil moist but not waterlogged. Lemon balm is drought-tolerant once established, but consistent moisture produces lusher growth.
Prune plants regularly to encourage bushiness and prevent flowering, which can reduce leaf production. Cut back stems by one-third in late spring or early summer.
Mulch around plants to retain moisture and suppress weeds. Use organic materials like straw or wood chips.
Lemon balm can be grown in containers at least 8 inches deep and 15-18 inches wide. Ensure proper drainage and place in a spot receiving at least 5 hours of direct sunlight daily.
Fertilization is generally unnecessary and may reduce the plant’s aromatic qualities. If needed, apply a balanced organic fertilizer in spring.
To prevent spreading, remove flower heads before they set seed. Consider planting in raised beds or containers to control growth.
Lemon balm is relatively pest-resistant but can occasionally suffer from powdery mildew. Ensure good air circulation and avoid overhead watering to prevent this issue.
Harvesting and Storage of Lemon Balm
Harvesting lemon balm is best done in the morning after the dew has dried but before the sun becomes too intense. This preserves the plant’s essential oils and flavors.
Use clean, sharp pruning shears to cut stems about 2-3 inches above the ground. Select healthy stems with vibrant green leaves for the best quality harvest.
For fresh use, store lemon balm in an airtight container or plastic bag in the refrigerator. It will stay fresh for several days.
To dry lemon balm, spread the leaves and stems in a single layer on a clean, dry surface. Allow them to air dry in a well-ventilated area away from direct sunlight.
Once fully dried, remove the leaves from the stems and store them in an airtight glass container. Keep the container in a cool, dark place to preserve flavor and potency.
Properly dried and stored lemon balm can last up to one year. Label the container with the date of harvest to track freshness.
Freezing is another option for long-term storage. Chop fresh leaves and place them in ice cube trays with water. Once frozen, transfer the cubes to a freezer bag for later use in teas or recipes.
