Lemon Balm Growing Guide for Zone 9

Planting Time: In Florida, plant lemon balm in early spring or fall. Lemon balm thrives in cooler weather but can also tolerate the heat of summer, making it suitable for both spring and fall planting.

Soil: Lemon balm prefers well-draining soil with a pH between 6.0 and 7.5. Adding compost or well-rotted manure to the soil can improve fertility and structure.

Sun: Lemon balm grows best in partial shade to full sun. In very hot climates, some afternoon shade can help prevent the leaves from scorching.

Watering: Keep the soil consistently moist but not waterlogged. Water regularly, especially during dry spells, to keep the soil evenly moist.

Spacing: Plant lemon balm seeds or transplants 18-24 inches apart. Lemon balm can spread and become invasive, so consider planting it in containers or using barriers to control its growth. Proper spacing ensures adequate air circulation and room for growth.

Fertilization:
N-P-K Ratio: Lemon balm benefits from a balanced fertilizer with a slightly higher nitrogen content to support lush, leafy growth, such as 10-10-10 or 20-10-10.

When to Add:

• Before Planting: Apply the fertilizer to the soil before planting seeds or transplants to promote strong initial growth.

• Early Spring: Reapply the fertilizer in early spring as new growth begins.

• Mid-Growing Season: If needed, reapply the fertilizer lightly every 4-6 weeks to support continued growth.

Application Tips:

• Follow the directions on the fertilizer package to avoid over-fertilization.

• Apply the fertilizer evenly around the base of the plants and water thoroughly to help the nutrients reach the roots.

Additional Tips:

• Lemon balm grows best in well-drained soil rich in organic matter, so consider adding compost to improve soil fertility and structure.

• Mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

• Ensure that lemon balm receives consistent moisture, especially during the growing season, to prevent stress and promote tender, flavorful leaves.
