Lemon balm (Melissa officinalis) is a delightful herb known for its light, citrusy scent and versatile uses. Often associated with stress relief, herbal teas, and natural remedies, lemon balm is also easy to grow, making it a favorite among gardeners. Whether you’re a beginner or an experienced green thumb, this guide will show you how to grow and care for lemon balm, so you can enjoy fresh, fragrant leaves all season long. In this article, we will explore everything from planting to harvesting, offering tips to ensure a healthy, thriving plant in your garden or containers.
Why Grow Lemon Balm?
Lemon balm belongs to the mint family, which means it shares some of mint’s hardy, fast-growing characteristics. While its main claim to fame is its lovely lemony fragrance, lemon balm is also rich in health benefits. It’s known for its calming properties and is commonly used to treat stress, anxiety, indigestion, and insomnia. Its leaves can be dried and used in teas, or fresh leaves can be added to salads, drinks, and other dishes to give them a refreshing twist.
With such a wide range of uses, lemon balm is a fantastic addition to any herb garden. And the best part? It’s a low-maintenance plant that adapts well to different growing environments.
How to Plant Lemon Balm
1. Choosing the Right Location
Lemon balm thrives in well-drained soil with moderate moisture. Ideally, it should be planted in a spot that receives full sun to partial shade. If you live in an area with very hot summers, some afternoon shade will prevent the leaves from scorching. If growing indoors, place the container near a sunny window or under grow lights.
Lemon balm can grow in both garden beds and containers. However, it’s important to note that like mint, lemon balm can spread rapidly if planted directly in the ground. If you want to avoid having it take over your garden, consider growing it in a pot or use some kind of barrier in the soil.
2. Planting Lemon Balm from Seeds or Cuttings
You can grow lemon balm either from seeds or cuttings, depending on your preference and availability.
- From seeds: Sow lemon balm seeds indoors in early spring about 6-8 weeks before the last frost date. Simply scatter the seeds on the surface of moist potting soil and lightly press them in. Lemon balm seeds need light to germinate, so don’t cover them too deeply. Once the seedlings are about 3-4 inches tall, transplant them outside, spacing them 12-18 inches apart.
- From cuttings: Alternatively, you can propagate lemon balm by taking cuttings from an established plant. Cut a healthy stem just below a node, remove the lower leaves, and place the cutting in water or moist soil. In a few weeks, roots will form, and you can transplant the cutting into a garden bed or pot.
3. Soil and Water Requirements
Lemon balm prefers rich, well-drained soil, but it can also tolerate a wide range of soil types. If you’re planting in containers, use a high-quality potting mix with good drainage. Adding compost to your garden soil can boost its fertility and help lemon balm thrive.
Lemon balm needs regular watering, especially during its first few weeks in the garden. Keep the soil consistently moist, but avoid waterlogging, which can lead to root rot. Once established, lemon balm becomes somewhat drought-tolerant, though it still performs best when watered regularly during dry spells.
Caring for Your Lemon Balm
1. Watering Tips
As mentioned, lemon balm prefers moist soil, but it’s important to avoid letting the soil become soggy. Water deeply and less frequently rather than giving it a little water every day. A good rule of thumb is to water when the top inch of soil feels dry to the touch.
If you live in an area with heavy rainfall, ensure that your lemon balm is planted in well-drained soil to prevent it from sitting in waterlogged conditions.
2. Pruning and Harvesting Lemon Balm
Pruning lemon balm not only keeps the plant looking tidy, but it also encourages fuller, bushier growth. You can start harvesting leaves once the plant reaches about 8 inches tall. Regularly cutting back the plant will prevent it from becoming leggy and will stimulate the growth of more tender, flavorful leaves.
When harvesting, snip stems about two-thirds of the way down. This encourages new shoots and keeps the plant producing leaves throughout the growing season. Be sure to remove any yellowing or damaged leaves to keep your plant healthy.
Lemon balm is most potent when harvested just before it flowers, typically in late spring or early summer. You can dry or freeze the leaves for later use, though many gardeners prefer to use them fresh for teas, salads, or garnishes.
3. Fertilizing
Lemon balm isn’t particularly demanding when it comes to fertilization. In fact, it can grow quite well in poor soil without any fertilizer at all. However, adding compost or a slow-release organic fertilizer once a year can provide your plant with a steady supply of nutrients.
Avoid over-fertilizing lemon balm, as it can lead to excessive leaf growth at the expense of the plant’s aromatic oils. A light application of compost in the spring should be more than enough to keep your lemon balm healthy and productive.
4. Pest and Disease Control
Lemon balm is relatively pest-resistant, but it can sometimes attract aphids, spider mites, or whiteflies. These pests can be controlled using organic insecticidal soap or by introducing beneficial insects like ladybugs into your garden.
Overwatering can lead to fungal diseases like powdery mildew. To prevent this, ensure your lemon balm is planted in well-drained soil, and avoid getting the leaves wet when watering.
How to Overwinter Lemon Balm
Lemon balm is a hardy perennial in USDA zones 4-9, meaning it will survive the winter and come back year after year. However, in colder climates, it may die back to the ground in the winter months. To protect your lemon balm from extreme cold, mulch around the base of the plant in late fall to insulate the roots.
If you’re growing lemon balm in containers, you can bring the pots indoors before the first frost. Place them in a sunny spot or under grow lights to keep them growing through the winter. Keep in mind that the plant may go dormant if the indoor conditions are not ideal.
Benefits of Growing Lemon Balm
Growing lemon balm offers numerous benefits beyond just its delightful fragrance. Here are some reasons why you should consider adding it to your garden:
- Culinary Uses: Lemon balm can be used in a wide variety of dishes, from fresh salads to marinades and desserts. Its mild, lemony flavor pairs well with fish, chicken, and fruit dishes.
- Herbal Teas: Fresh or dried lemon balm leaves make a calming, aromatic tea that helps alleviate stress, anxiety, and digestive issues.
- Attracts Pollinators: Lemon balm’s small white flowers attract bees and other pollinators, making it a great addition to a pollinator-friendly garden.
- Natural Remedy: Lemon balm has long been used in traditional medicine for its calming effects. It’s commonly used to treat anxiety, insomnia, and even cold sores.
