Lemon balm

Lot location: 6.7 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. Zone 4a
