How to Grow Lavender

Lavender (Lavandula spp.) is a fragrant perennial herb prized for its aromatic flowers, essential oils, and ornamental beauty. It thrives in full sun, well-drained soil, and dry conditions. This guide explains planting, care, harvesting, and climate considerations suitable for all regions.

Where Should You Plant Lavender?

  • Best location: Full sun; lavender produces the strongest fragrance and blooms with ample light.
  • Soil: Well-drained, sandy or rocky soil; pH 6.5–7.5.
  • Moisture: Low to moderate moisture; lavender prefers dry conditions once established.

When Should You Plant Lavender?

  • Start indoors: Begin seeds 8–10 weeks before transplanting; germination is slow.
  • Transplanting: Move outdoors once temperatures remain warm and stable.
  • Direct planting: Suitable in warm climates; plant when soil is workable and dry.

How Do You Plant Lavender?

  • Depth: Sow seeds on the soil surface or lightly cover; seedlings establish slowly.
  • Spacing: Space plants 12–18 inches apart; larger varieties may need 24 inches.

Which Plants Grow Well With Lavender?
