How to Grow Marjoram
Origanum majorana
Marjoram is a tender perennial herb often grown as an annual for its delicate, sweet flavor in salads and sauces. Gardeners prize this easy-to-grow plant for its compact size and ability to thrive in containers or garden beds across many zones.
Starting Marjoram: indoors or direct sow?
🌾 Sow directly in the garden — Marjoram is not usually started indoors.
Because marjoram is a tender perennial grown as an annual, start seeds indoors 4 to 6 weeks before your last frost date, then transplant seedlings outdoors only after all danger of frost has passed.
Soil, care & harvest
Prepare well-draining soil with a pH between 6.0 and 8.0 before sowing marjoram seeds indoors. Start seeds 4 to 6 weeks before your last frost date, placing them about one-quarter inch deep in seed trays. Expect germination within 7 to 14 days once warmth is established.
Space plants 6 to 12 inches apart to ensure good air circulation and growth. Marjoram requires low to moderate water but dries out quickly, so water regularly while allowing the soil to dry slightly between sessions. Apply a light mulch to retain moisture and feed sparingly if growth slows.
Watch for aphids or powdery mildew, which can be prevented by ensuring good airflow and avoiding overhead watering. Harvest sprigs when they are well-established but before flowering begins. You can typically harvest the plant between 70 and 90 days after sowing for fresh culinary use.
