Common Mugwort

Choosing Mugwort

Hi there, gardening friend! Common mugwort is a hardy plant that grows well in most conditions. If you're starting from seeds, you can find them online or at garden centers. Alternatively, if you have access to an existing mugwort plant, you can take cuttings or divide the roots for propagation.

Tip: Mugwort spreads quickly and can become invasive, so consider planting it in a contained area or pot to keep it under control.

Timing

Mugwort is quite forgiving when it comes to timing. You can plant seeds or root divisions in early spring after the last frost, or even in early fall. It prefers cool weather but can tolerate heat as long as it has enough moisture.

Tools and Materials

Mugwort seeds, cuttings, or root divisions

Pots (at least 12 inches deep with good drainage) or garden space

Regular garden soil

Watering can

Shovel or trowel

Tip: Choose a spot where mugwort won’t compete with other plants, as it tends to spread aggressively.

If Using Seeds:

1. Fill small pots or seed trays with moist soil.
2. Sprinkle seeds on top of the soil and lightly press them down without covering them too much.
3. Water gently to keep the soil moist but not soggy.
4. Place in a sunny or partially shaded spot.
5. Seeds will germinate in about 1-3 weeks.
6. Once seedlings are a few inches tall, they’re ready to transplant.

If Using Cuttings or Root Divisions:

1. Prepare a pot or dig a hole in your garden.
2. Plant the cutting or root division just below the soil surface.
3. Gently firm the soil around the plant.
4. Water thoroughly until water drains from the bottom of the pot or seeps into the ground.

Tip: Mugwort isn’t picky about soil type but does best in well-drained soil. Avoid waterlogged areas.

Sunlight Requirements

Mugwort loves sunlight but can handle partial shade. Aim for at least 4-6 hours of direct sunlight daily. If you live in a very hot climate, some afternoon shade might be beneficial.

Watering Method

• Water regularly, especially during dry spells.
• The soil should be kept moist but not waterlogged.
• Check the soil every few days by sticking your finger in – if it feels dry up to the first knuckle, it’s time to water.

Tip: Overwatering is usually not a problem with mugwort, but ensure good drainage to prevent root rot.

Fertilizing Tips

• Mugwort doesn’t require heavy fertilization.
• A light application of compost or general-purpose fertilizer once a year in early spring is sufficient.
• Too much fertilizer can cause excessive spreading, so use sparingly.

Controlling Spread

Because mugwort can become invasive, regularly check its growth and remove any unwanted shoots or roots. Growing it in a large pot or using barriers in the ground can help manage its spread.

When to Harvest

You can start harvesting mugwort leaves anytime after the plant is established, typically a few months after planting. The best time to harvest is just before flowering when the essential oils are most concentrated.

How to Harvest

1. Use clean scissors or pruning shears to cut the stems.
2. Harvest leaves and young shoots as needed.
3. For drying, gather larger bunches of stems and hang them upside down in a dry, airy place out of direct sunlight.

Storage

• Fresh leaves can be stored in the refrigerator for a few days.
• Dried leaves can be stored in airtight containers in a cool, dark place for several months.
• Mugwort can also be used fresh in teas or cooked dishes.

Tip: Always wear gloves when handling mugwort, as it can cause skin irritation in some people.

1. Yellow Leaves

Cause: Could be due to overwatering, poor drainage, or nutrient deficiency.

Solution: Check soil moisture and adjust watering. Ensure good drainage and apply a light fertilizer if necessary.

2. Plant Spreading Too Much

Cause: Mugwort naturally spreads through rhizomes.

Solution: Regularly prune and remove unwanted growth. Consider growing in pots or using underground barriers.

3. Not Flowering

Cause: Insufficient sunlight or nutrients.

Solution: Ensure the plant gets enough sunlight and apply a balanced fertilizer sparingly.

4. Pest Infestation

Cause: Rare, but aphids or spider mites might appear.

Solution: Rinse the plant with water or use insecticidal soap. Maintain good air circulation around the plant.

5. Wilting

Cause: Usually due to underwatering or extreme heat.

Solution: Increase watering frequency and provide some shade during the hottest part of the day.
