Lavender Growing Guide for Zone 9

Planting Time: In Florida, plant lavender in early spring or fall. Lavender thrives in warm, sunny weather and can tolerate the heat of summer, making it suitable for both spring and fall planting.

Soil: Lavender prefers well-draining, slightly alkaline soil with a pH between 6.5 and 7.5. Adding sand or gravel to the soil can improve drainage. Compost or well-rotted manure can improve fertility and structure.

Sun: Lavender grows best in full sun, requiring at least 6-8 hours of direct sunlight daily.

Watering: Keep the soil consistently moist but not waterlogged during the establishment period. Once established, lavender is drought-tolerant and prefers to dry out between waterings.

Spacing: Plant lavender seeds or transplants 18-24 inches apart. Lavender can spread, so proper spacing ensures adequate air circulation and room for growth.

Fertilization:
N-P-K Ratio: Lavender benefits from a balanced fertilizer with a slightly higher potassium content to support overall plant health and flowering, such as 5-10-10 or 10-10-10.

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 6-8 weeks to support continued growth and blooming.

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:

• Lavender grows best in well-drained, sandy soil with a slightly alkaline pH, so consider adding lime if your soil is acidic.

• Avoid over-watering lavender, as it is drought-tolerant and prefers dry conditions.

• Mulch around the plants with gravel or small stones to improve drainage and prevent weeds.
