Dillleaf Wormwood Plant Care

Dillleaf Wormwood (Artemisia anethifolia) belongs to the Asteraceae family within the Artemisia genus. Dillleaf Wormwood is native to Eurasia and Africa. Dillleaf Wormwood is also known as Artemisia anethifolia.

Dillleaf Wormwood displays an upright, bushy shrub growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Dillleaf Wormwood produces insignificant small yellow or white flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Dillleaf Wormwood every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Dillleaf Wormwood thrives in full sun to partial shade.

Artemisia anethifolia tolerates temperatures of 50–75°F. Dillleaf Wormwood prefers humidity levels of 30–60%.

Well-draining sandy soil with low fertility. Good drainage is essential for Dillleaf Wormwood to prevent waterlogging, which leads to root rot and fungal issues.

Feed Dillleaf Wormwood every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining sandy soil with low fertility. Avoid low spots where water collects after rain.

Dillleaf Wormwood is suited to USDA Zone 4a – 8b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Dillleaf Wormwood can spread to about 3 ft (0.9 m) and reach about 2 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Dillleaf Wormwood while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Dillleaf Wormwood is hardy down to USDA zone 4a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Dillleaf Wormwood can be propagated through seeds, division. Similar propagation techniques also apply to southernwood plant care, which shares the same genus.

Dillleaf Wormwood is susceptible to aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Dillleaf Wormwood grows outdoors in USDA Zone 4a – 8b. It survives winters down to planting zone 4a. Dillleaf Wormwood is native to Eurasia and Africa.
