Wormwood Plant Care

Wormwood (Artemisia absinthium) belongs to the Asteraceae family within the Artemisia genus. Wormwood is native to North Africa and temperate regions of Eurasia, and widely naturalized in Canada and the northern United States. Wormwood is also known as Absinthe Wormwood, Green Ginger, Absinthium bipedale.

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

Leaf size: approximately 2 inches.

Artemisia absinthium requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Wormwood thrives in full sun to partial shade light conditions. The optimal light range is 200–1000 lux. Avoid placing Wormwood in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Artemisia absinthium grows best at temperatures between 50°F and 75°F. Wormwood prefers humidity levels of 30–60%.

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

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

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

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.

Wormwood grows outdoors in USDA Zone 12a. Native to North Africa and temperate regions of Eurasia, and widely naturalized in Canada and the northern United States, Wormwood is adapted to warm climates. In cooler regions, grow Wormwood as a houseplant or bring it indoors before the first frost.
