Lemon Balm Growing Conditions

Lemon balm grows well in warm environments with loose, well-drained soil. The plant prefers light, so if you plant outdoors, choose a location with indirect light or partial shade. The ideal soil pH is between 6.0 and 7.0, which helps the plant grow vigorously and produce lush foliage.

Plant Care

Lemon balm needs to be watered regularly but not too wet. It is also quite disease-resistant, but you must prune it regularly to keep it healthy and prevent excessive spread.

Harvesting and Drying

Harvest lemon balm when the plant reaches a height of about 15–20 cm. Trim the young leaves in the early morning when the essential oils in the leaves are at their highest. After harvesting, dry the leaves in a cool, dry environment to preserve the flavor and active compounds of the plant.
