Marjoram (Origanum majorana) is a fragrant perennial herb valued for its sweet, mild flavor and culinary versatility. It thrives in full sun, well-drained soil, and adapts easily to warm, dry conditions. This guide explains planting, germination, care, harvesting, and climate considerations suitable for all regions.

  • Best location: Full sun; marjoram produces the strongest aroma and leaf growth with ample light.
  • Soil: Well-drained, moderately fertile soil; pH 6.0–7.5.
  • Moisture: Low to moderate moisture; marjoram prefers dry conditions once established.

When Should You Plant Marjoram?

  • Start indoors: Begin seeds 6–8 weeks before transplanting; germination is slow.
  • Transplanting: Move outdoors once temperatures remain warm and stable.
  • Direct sow: Suitable in warm climates; plant when soil is workable and dry.

How Do You Plant Marjoram?

  • Depth: Sow seeds on the soil surface or lightly cover; seedlings establish slowly.
