Field Wormwood Plant Care

Field Wormwood (Artemisia campestris subsp. bottnica) belongs to the Asteraceae family within the Artemisia genus. Field Wormwood is native to Finland, Sweden and Karelia. Field Wormwood is also known as Field Sagewort.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Field 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.

Field Wormwood thrives in full sun to partial shade.

Artemisia campestris subsp. bottnica tolerates temperatures of 50–75°F. Field Wormwood prefers humidity levels of 30–60%.

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

Feed Field 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.

Field Wormwood is suited to USDA Zone 12a.

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.

Field 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 Field 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.

Field Wormwood is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

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

Field 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.

Field Wormwood grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Field Wormwood is native to Finland, Sweden and Karelia. In cooler regions, grow Field Wormwood as a houseplant or bring it indoors before the first frost.
