Planting

How to Grow

  1. Tuck seeds or cuttings into well-draining soil in spring.

  3. Mist cuttings regularly to maintain humidity.
  4. Transplant when seedlings are strong and roots are developed, about 6 weeks.
  5. Prune lightly after flowering to promote bushiness.
  6. Mulch around plants to conserve moisture and suppress weeds.

Pro Tip

Choose a sunny, well-drained spot for optimal growth and aromatic foliage.
