How to Grow Lemon Balm

Lemon balm (Melissa officinalis) is a fragrant herb that’s easy to grow and offers a variety of uses, from culinary to medicinal. Below is a guide on how to plant, grow, and harvest lemon balm.

Planting Lemon Balm

  1. Choosing a Location:
    • Lemon balm prefers a spot with full sun to partial shade. It grows best in well-drained soil with a pH of 6.7 to 7.3.
    • It can be planted in garden beds or containers. If growing in a container, ensure it’s at least 8 inches deep.
  2. When to Plant:
    • Plant lemon balm in the spring after the last frost. If starting from seeds, you can begin indoors 6 to 8 weeks before the last expected frost.
  3. Starting from Seeds or Transplants:
    • Seeds: Sow seeds just below the soil surface. Keep the soil moist until the seeds germinate, usually in 7 to 14 days.
    • Transplants: Space plants 18 to 24 inches apart. Water thoroughly after planting.

Growing Lemon Balm

  1. Watering:
    • Lemon balm prefers consistently moist soil. Water regularly, especially during dry periods. However, avoid overwatering, as it can lead to root rot.
  2. Fertilizing:
    • Lemon balm doesn’t need heavy fertilization. A light application of compost or a balanced, all-purpose fertilizer in the spring should suffice.
  3. Pruning:
    • Regular pruning helps maintain the plant’s shape and encourages bushy growth. Cut back the plant after the first bloom to encourage a second flush of leaves.
  4. Pest Control:
    • Lemon balm is generally pest-resistant, but watch out for aphids and spider mites. Treat with insecticidal soap if needed.

Harvesting Lemon Balm

  1. When to Harvest:
    • You can begin harvesting lemon balm leaves once the plant is established, usually about 10 to 12 weeks after planting.
    • For the best flavor, harvest leaves in the morning after the dew has dried but before the heat of the day.
  2. How to Harvest:
    • Snip off the leaves or cut the stems with scissors. You can take up to one-third of the plant at a time without harming it.
    • To encourage new growth, regularly pinch off the tips of the stems.
  3. Drying and Storing:
    • Lemon balm can be used fresh or dried for later use. To dry, hang small bunches in a warm, dry, and well-ventilated area out of direct sunlight.
    • Once dry, store the leaves in an airtight container in a cool, dark place. Dried lemon balm retains its flavor for up to a year.

Uses for Lemon Balm

  • Culinary: Add fresh lemon balm to teas, salads, marinades, or desserts for a lemony flavor.
  • Medicinal: It is often used in teas for its calming effects and is believed to aid digestion and alleviate stress.
  • Aromatherapy: The essential oil from lemon balm is used in aromatherapy for its soothing properties.
