Mugwort Plant Seeds:
Guide to Storing, Sowing and Germination

Mugwort (Artemisia vulgaris) is a versatile and hardy plant that has been used for centuries for its medicinal and culinary properties. If you’re interested in growing mugwort in your garden or indoor space, it’s important to understand the process of storing, sowing, and germinating its seeds. In this guide, we will take you through the steps to successfully grow mugwort from seed.

Storing Mugwort Seeds

Before you start sowing mugwort seeds, it’s crucial to ensure their viability by storing them properly. Here are some tips to help you store mugwort seeds effectively:

1. Collecting Seeds: Harvest mugwort seeds when they are fully matured, usually in late summer or early fall. Look for dried flowers on the plant that have turned brown and papery. Cut or shake the seed heads gently over a clean tray or a paper bag to collect the seeds.

2. Cleaning Seeds: Remove any debris or chaff from the collected seeds by gently rubbing them between your fingers. Be careful not to damage the seeds in the process.

3. Drying Seeds: Place the cleaned seeds in a cool and dry location for about two weeks to ensure complete drying. Spread them out on a clean tray or paper towel and stir them occasionally to prevent mold or mildew formation.

4. Storage Containers: Once the seeds are fully dried, transfer them into an airtight container such as a glass jar or a small ziplock bag. Make sure to label the container with the date of collection and the seed variety.

5. Ideal Storage Conditions: Mugwort seeds can remain viable for up to three years if stored properly. Keep the container in a cool, dark, and dry place like a refrigerator or a cellar. Avoid exposing them to moisture or extreme temperature fluctuations.

Sowing Mugwort Seeds

Now that you have properly stored mugwort seeds, it’s time to sow them. Here’s a step-by-step guide to help you with the sowing process:

1. Growing Medium: Choose a well-draining soilless potting mix or seed starting mix for sowing mugwort seeds. Fill a seed tray or small pots with the chosen growing medium, leaving about half an inch of space at the top.

2. Sowing Depth: Mugwort seeds are tiny and require light to germinate. Therefore, they should be sown on the surface of the growing medium without covering them with soil. Gently press the seeds into the surface, ensuring good seed-to-soil contact.

3. Moisture: After sowing, mist the surface of the growing medium with water to provide moisture for germination. Be careful not to overwater, as excessive moisture can lead to rotting or fungal issues.

4. Covering the Tray: To create a suitable microclimate for germination, cover the seed tray with a clear plastic lid or a plastic wrap. This helps retain moisture and warmth around the seeds.

5. Ideal Temperature and Light: Place the covered seed tray in a warm location with temperatures around 70-75°F (21-24°C). Mugwort seeds require light for germination, so ensure they receive indirect sunlight or provide artificial grow lights if necessary.

6. Germination Time: Mugwort seeds usually take around 10-14 days to germinate, though it can vary depending on the conditions provided. Check the tray regularly for signs of germination such as tiny green sprouts emerging from the seeds.

Germinating Mugwort Seeds

Once your mugwort seeds have germinated, it’s important to provide them with proper care to ensure healthy growth. Here are some guidelines for nurturing germinated mugwort seeds:

1. Removing the Cover: Once the seedlings have emerged, remove the plastic cover to prevent excessive humidity and encourage air circulation. This helps prevent fungal diseases and promotes stronger growth.

2. Watering: Keep the soil lightly moist throughout the seedling stage. Water the mugwort seedlings gently from the base to avoid disturbing their delicate roots. Avoid overwatering, as it can cause root rot.

3. Transplanting Seedlings: When the mugwort seedlings have developed a few sets of true leaves and are sturdy enough, they can be transplanted into individual pots or directly into your garden. Ensure they are spaced at least 12-18 inches apart to provide enough room for growth.

4. Growing Conditions: Mugwort thrives in full sun to partial shade and prefers well-draining soil. Regularly monitor moisture levels in the soil and water when it feels dry to touch.

5. Pruning: To encourage bushier growth, pinch back the growing tips of mugwort plants once they reach a height of around 6-8 inches. This promotes branching and results in a fuller plant.

By following these steps for storing, sowing, and germinating mugwort seeds, you’ll be well on your way to enjoying the benefits of this versatile plant in your own garden or indoor space. Whether you’re interested in its medicinal properties or simply want to add an attractive herb to your collection, growing mugwort from seed can be a rewarding experience. Happy gardening!
