Updated: July 19, 2023

Introduction

Marjoram is a popular herb known for its aromatic leaves, which are commonly used in cooking and herbal remedies. If you’re interested in growing marjoram in your garden, it’s important to understand how to properly store, sow, and germinate marjoram plant seeds. In this guide, we will provide you with all the information you need to successfully grow marjoram from seed.

Storing Marjoram Seeds

Before sowing marjoram seeds, it’s essential to properly store them to ensure their viability. Here are a few steps to follow when storing marjoram seeds:

  1. Harvesting: To obtain marjoram seeds, allow the plant to flower and produce seed pods. Once the pods have turned brown and dried out, carefully collect them by cutting the stems just below the pods.

  2. Drying: Place the collected seed pods in a well-ventilated room or paper bag to dry for about two weeks. Make sure the area is cool and dry to prevent mold or mildew formation.

  3. Seed Extraction: After the seed pods have fully dried, gently crush them with your hands or use a mortar and pestle to release the tiny marjoram seeds.

  4. Cleaning: Remove any remaining debris or chaff from the seeds by gently blowing or using a sieve with fine mesh.

  5. Storage: Store the cleaned marjoram seeds in a cool, dark, and dry place. Airtight containers like glass jars or seed envelopes work well for this purpose. Be sure to label the container with the date of harvest for future reference.

By following these steps, you can ensure that your marjoram seeds remain viable for several years.

Sowing Marjoram Seeds

Once you have properly stored your marjoram seeds, it’s time to sow them. Here’s a step-by-step guide to sowing marjoram seeds:

  1. Timing: Marjoram seeds can be sown either directly outdoors or indoors, depending on your climate and preference. If you live in a region with cold winters, it’s best to start the seeds indoors about 6-8 weeks before the last frost date.

  2. Soil Preparation: Prepare a well-draining soil mix by combining equal parts of potting soil, perlite, and vermiculite. Fill seed trays or small pots with this mixture, leaving about half an inch of space at the top.

  3. Sowing: Scatter the marjoram seeds evenly over the soil surface, aiming for about 2-3 seeds per inch. Lightly press the seeds into the soil to ensure good seed-to-soil contact.

  4. Watering: Gently mist the soil surface with water to avoid displacing the seeds. Keep the soil consistently moist but not soggy throughout the germination process.

  5. Germination: Place the seed trays or pots in a warm location with temperatures around 70-75°F (21-24°C). Marjoram seeds typically take 7-14 days to germinate.

Germination and Care

Once your marjoram seeds have germinated, it’s important to provide them with proper care to ensure healthy growth. Here are some essential tips for caring for marjoram seedlings:

  1. Lighting: After germination, move the seedlings to a bright location where they receive at least 6-8 hours of direct sunlight each day. If growing indoors, consider using fluorescent grow lights to supplement natural light.

  2. Watering: Water the marjoram seedlings consistently, keeping the soil evenly moist but not waterlogged. Avoid overwatering as this can lead to root rot.

  3. Thinning: If multiple seedlings emerge from one spot, gently thin them out by removing the weaker ones. This will allow the remaining plants to have enough space to grow and develop properly.

  4. Transplanting: Once the danger of frost has passed and the seedlings have developed at least two sets of true leaves, they can be transplanted into larger pots or directly into the garden. Space the plants about 12-18 inches apart to provide adequate airflow and prevent overcrowding.

  5. Maintenance: Regularly pinch back the tips of the marjoram plants to encourage bushier growth. Additionally, remove any weeds or competing plants that may hinder the marjoram’s growth.

By following these care tips, you’ll be able to enjoy a bountiful harvest of fresh marjoram leaves within a few months.
