How to Grow Lavender Successfully in Your Garden

Lavender thrives in well-draining soil with full sun exposure and minimal watering once established. Plant in spring, space properly for airflow, and prune annually after flowering.

  1. Find Full Sun and Drainage. Select a spot that receives at least 6-8 hours of direct sunlight daily. Lavender needs excellent drainage, so avoid low-lying areas where water collects. A south-facing slope or raised bed works perfectly. The location should have good air circulation to prevent fungal issues.
  2. Amend for Perfect Drainage. Test your soil pH - lavender prefers slightly alkaline soil between 6.5-7.5. If your soil is acidic, add lime several weeks before planting. Most importantly, improve drainage by mixing in coarse sand, perlite, or small gravel. Heavy clay soils need the most amendment - consider creating a raised bed if drainage is poor.
  3. Plant at Optimal Spacing. Plant lavender in spring after the last frost when soil temperatures reach 60°F consistently. If starting from seeds, begin indoors 10-12 weeks before the last frost. For transplants, dig holes twice as wide as the root ball and just as deep. Space plants 12-18 inches apart for smaller varieties, 2-3 feet for larger ones.
  4. Master the Drought Schedule. Water deeply but infrequently. Newly planted lavender needs regular watering for the first few weeks, then reduce frequency. Established plants are drought-tolerant and typically need watering only during extended dry periods. Always water at soil level, never on the foliage, and allow soil to dry between waterings.
  5. Cut Back for Bushier Growth. Prune lavender annually in late summer after flowering or in early spring. Remove spent flower stalks and trim back about one-third of the plant's height, cutting just above new growth. Never cut into old woody stems as they rarely regenerate. Light pruning throughout the growing season encourages bushier growth.
  6. Skip the Extra Feeding. Lavender thrives in poor soil and rarely needs fertilizing. Over-fertilization reduces essential oil production and makes plants leggy. If your soil is extremely poor, apply a light dose of balanced, slow-release fertilizer in early spring. Compost worked into the soil at planting time is usually sufficient.
