Seedling
2-3 weeksTiny seedlings with 2-4 true leaves; delicate and light green
Keep soil consistently moist but not waterlogged. Thin seedlings to 6-8 inches apart when they have 2-3 true leaves. Provide bright light.
Vegetative Growth
4-8 weeksPlant develops branching stems with increasingly feathery, finely divided leaves; grows 1-2 feet tall
Pinch back growing tips to encourage bushiness. Reduce watering as plant establishes. Begin harvesting leaves once plant has 8+ leaves.
Flowering
4-8 weeksSmall, inconspicuous greenish-brown or yellowish flowers appear in terminal spikes; plant reaches 3-5 feet tall
Flowers develop mid to late summer. Deadhead spent flowers to redirect energy to foliage, or allow flowering for ornamental interest. Can self-seed prolifically.
Maturity & Dormancy
Ongoing; perennial cycle repeats annuallyPlant reaches full size; foliage may decline in heat or dry conditions; dies back in winter (perennial regrows from roots)
Cut back plant to 3-4 inches above ground in late fall or early spring. Remove spent flowers before seeds disperse if you want to prevent spreading. Apply mulch in cold climates.
Common Pests
-
Spray with water to dislodge; use insecticidal soap if severe. Mugwort's strong odor often repels pests, but heavy infestations may occur in humid conditions.
-
Increase humidity; spray with water. Use neem oil or miticides if infestation is severe.
-
Hand-pick in early morning; use row covers on young plants. Mugwort is generally less susceptible than many plants.

Harvest Tips
Harvest leaves anytime during the growing season once plant is established. Best flavor is before flowering. Cut stems early morning after dew dries. For drying, cut entire stems and hang upside down in bundles in a warm, dry place. Leaves dry quickly (1-2 weeks) and can be stored in airtight containers for months. Pinch off flower buds to encourage continuous leaf production.
