How to Grow Mugwort Plant Outdoors

Updated: July 25, 2023

Mugwort (Artemisia vulgaris) is a perennial herb that has been used for centuries in traditional medicine and spiritual practices. It is known for its unique aroma, medicinal properties, and ability to attract beneficial insects to the garden. If you are interested in growing mugwort in your outdoor space, here are some tips to help you get started.

Choosing the Right Location

Mugwort is a hardy plant that can tolerate a wide range of growing conditions. However, it thrives in full sun or partial shade and prefers well-draining soil. Before planting, make sure to choose a location that receives at least 6-8 hours of sunlight per day and where the soil is not waterlogged.

Preparing the Soil

Preparing the soil before planting is crucial for the success of your mugwort plants. Start by removing any weeds or grass from the planting area. Then, loosen the soil using a garden fork or tiller to improve drainage and allow the roots to penetrate easily.

Mugwort prefers slightly acidic to neutral soil with a pH range between 5.5 and 7.0. You can amend the soil by adding organic matter such as compost or well-rotted manure to improve fertility and drainage.

Planting Mugwort

Mugwort can be grown from seeds or cuttings. If starting from seeds, sow them directly into the prepared soil after the last frost date in your area. The seeds are tiny, so sprinkle them evenly over the soil surface and lightly cover them with a thin layer of soil.

For cuttings, take 6-8 inch stem cuttings from an existing mugwort plant in early spring or late summer. Remove the lower leaves and dip the cut end into a rooting hormone powder to encourage root development. Plant the cuttings in pots filled with well-draining potting mix, keeping the soil lightly moist until new growth appears.

Space the plants about 18-24 inches apart to allow for proper air circulation and growth. Water the newly planted mugwort thoroughly, and continue to keep the soil evenly moist until the plants become established.

Care and Maintenance

Mugwort is a low-maintenance plant that requires minimal care once established. Here are some tips to keep your mugwort healthy and thriving:

Watering

Mugwort has moderate water needs and prefers consistently moist soil. Water deeply once or twice a week, depending on the weather conditions. Avoid overwatering, as this can lead to root rot. Mulching around the plants can help retain moisture and suppress weed growth.

Fertilizing

Mugwort doesn’t require heavy fertilization but can benefit from a light application of balanced organic fertilizer in early spring. Avoid using high-nitrogen fertilizers, as they can promote excessive foliage growth at the expense of flower production.

Pruning

To maintain compact and bushy mugwort plants, pinch off the tips of young stems when they reach about 6 inches in height. This will encourage branching and result in a fuller plant. Additionally, remove any dead or yellowing leaves regularly to prevent disease and pest issues.

Controlling Pests and Diseases

Mugwort is resistant to most pests and diseases. However, it can occasionally be affected by aphids, spider mites, or powdery mildew. Monitor your plants regularly and take appropriate action if you notice any signs of infestation or disease. In some cases, a strong blast of water or insecticidal soap can help control pests, while neem oil can be effective against powdery mildew.

Harvesting Mugwort

Mugwort is typically harvested for its leaves and flowers. For culinary purposes, harvest the leaves when they are young and tender. Simply snip off individual leaves or cut back the entire plant by about one-third to promote new growth.

For medicinal use, harvest the leaves and flowers just as the flowers begin to open. Hang them upside down in a cool, dark place to dry. Once fully dry, store the leaves and flowers in an airtight container away from direct sunlight.

Conclusion

Growing mugwort outdoors can be a rewarding experience for both gardeners and herbal enthusiasts. With its hardy nature and beneficial properties, it is a valuable addition to any garden. By choosing the right location, preparing the soil, and providing proper care, you can enjoy a healthy and thriving mugwort plant in your outdoor space. So why not give it a try and see the magic of mugwort unfold in your garden?
