How to plant

Plant it well.

Plant seeds directly in the garden or transplant according to the herb; avoid burying the crown.

Indoors or containers

Suitable for a bright window or grow light; use individual pots with drainage.

Keep it growing

Care through the season.

  • Pinch or harvest regularly to encourage branching.
  • Remove flowers when leaf production is the goal.
  • Avoid overfertilizing, which can dilute flavor and cause weak growth.
What to avoid

Overwatering or waiting too long between harvests can reduce flavor and vigor.

Ready to harvest

Know the cue, not just the date.

  • Pinch 4–6 inch tips above a leaf pair before flowering; harvest frequently.
  • Harvest during the cool part of the day when practical. Use clean tools, then cool, store or use the harvest promptly.
