Basil (Ocimum x citriodorum) 'Lemon'.

Lemon basil (Ocimum x citriodorum) is a delightful herb that combines the flavors of lemon and basil. It is a hybrid between basil and lemon scented geranium and is native to tropical regions of Asia and Africa.

It thrives in full sun to partial shade, with at least 6 hours of direct sunlight each day. To grow lemon basil, choose the right location with well-draining, fertile soil rich in organic matter.

Timing: Sow lemon basil seeds indoors 6-8 weeks before the last expected frost date in your area or start seeds outdoors once the soil has warmed to at least 60°F (15°C). Space seedlings or transplants 10-12 inches apart in rows spaced 18-24 inches apart.

Watering: Keep the soil consistently moist but not waterlogged. Avoid letting the soil dry out completely, as this can stress the plants. Fertilizing: Use a balanced organic fertilizer at planting time and again every 4-6 weeks during the growing season to provide essential nutrients.

Pruning and Pinching: Regularly pinch off the top leaves of the plant to encourage bushy growth and prevent it from becoming leggy. Prune back the plant by about one-third after it has reached 6-8 inches in height to promote more branching and leaf production. Remove any flowers that appear to keep the plant focused on leaf growth and maintain its flavor.

Mulching: Apply a 2-inch layer of mulch around the base of the plants to help retain moisture and suppress weed growth. Lemon basil prefers warm temperatures between 65-85°F (18-29°C), so protect it from frosts or grow it in a container that can be moved indoors if necessary. High humidity is beneficial, so consider misting the leaves or placing the plant near a water feature if your climate is dry.

Pest and Disease Control: Keep an eye out for common basil pests such as aphids, spider mites, and slugs. Use organic pest control methods like neem oil or insecticidal soap to manage infestations.

Harvesting: Start harvesting lemon basil leaves once the plant is at least 6 inches tall, pinching or snipping off the leaves at the base, taking care not to strip the plant bare.

Cooking and Use: Use fresh lemon basil leaves in various dishes, pairing well with other herbs like thyme, rosemary, and mint.
