Lemon balm is a perennial herb; pretty by itself as an ornamental or delicious when used as a tea.
- Plant lemon balm during the warm weather of late spring, once all chances of frost have passed.
- Space lemon balm 20 to 24 inches apart in an area with partial shade and fertile, well-drained soil with a pH of 6.5 to 7.0.
- Start the growing season off right by mixing several inches of aged compost or other rich organic matter into your native soil.
- Check soil moisture every few days and water when the top inch becomes dry.
- Maximize leaf production by regularly feeding with water-soluble plant food.
- Harvest lemon balm leaves anytime once your plant reaches 6 to 8 inches tall; avoid harvesting more than one-third of the plant at a time.
