Growing Tips

  • Lavender must have excellent drainage — it will die in wet or clay soil.
  • Plant on a slope or raised bed, or add gravel to the planting hole.
  • Prune by one-third after flowering — never cut into old wood.
  • In zones 5–6, mulch around the base with gravel (not wood chips) to protect roots.
  • Harvest flower spikes when one-third of the flowers are open for best fragrance.

Common Mistakes

  • Planting in clay or wet soil — lavender roots rot within a season.
  • Over-fertilizing — rich soil reduces fragrance and makes plants floppy.
  • Cutting into old wood — lavender won't regrow from bare wood.
  • Using wood chip mulch — traps moisture. Use gravel or sand instead.

Companion Planting

Companion planting improves growth, deters pests, and makes better use of garden space.
