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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
