However, it also makes a great addition to beds and borders, and cottage or informal gardens. Grow lemon balm with pest-repelling partners such as asters, sunflowers, lavender, or marigolds.

Soil Type
Water: Lemon balm thrives in moist soil and prefers consistent moisture, similar to its Mediterranean origins. It is moderately drought-tolerant but benefits from weekly watering. Outdoor cultivation enhances its aromatic leaves, and mulching helps retain moisture, reducing watering frequency.
Fertilize: For vibrant growth, lemon balm needs balanced nutrition with a 10-10-10 NPK fertilizer applied bi-monthly during the growing season. Use half the recommended dose initially to protect roots. Reduce fertilization in dormancy and adjust as lemon balm matures, monitoring its response for optimal vigor.
Pruning: Lemon balm, a fragrant herb used medicinally and culinarily, thrives with regular pruning. Trim stems to encourage bushier growth and remove dead foliage, ideally from early to late spring. This practice boosts airflow, reduces disease risk, prevents legginess, and supports vigorous health and frequent harvests.
Propagation: Lemon balm is best propagated in Spring via sowing and has a moderate difficulty level. Successful propagation is indicated by new growth and healthy leaves. For optimal results, ensure well-draining soil and consistent moisture.
Repotting: Lemon balm should be repotted every 2-3 years in spring into a slightly larger pot to support its bushy growth. Use well-draining soil and maintain regular watering until roots establish. Bright light and pruning prevent legginess, enhancing the aromatic leaves during its rapid growth phase.
