How to Grow Lemon Balm

Planting and care

Give lemon balm partial shade and well-drained soil. It spreads readily, so site it where it can roam or contain it in a pot.

1. 1Plant after frost — Set out transplants in late spring about 18 inches apart, or sow seed on the surface with only light covering.
2. 2Water then ease off — Keep soil moist while establishing, then avoid overwatering to prevent root rot.
3. 3Cut back after bloom — Shear plants after flowering to reduce vigorous self-seeding and spread.

Harvesting

Pick leaves anytime once plants are 6 to 8 inches tall, avoiding more than a third of the plant. Leaf oils are strongest as flower buds form, which is the best time to gather leaves for drying.
