Prairie dogweed Plant Care

Prairie dogweed (Dyssodia papposa) belongs to the Asteraceae family within the Dyssodia genus. Prairie dogweed is native to North America and parts of the Southwest, extending into the Northeast. Prairie dogweed is also known as Prairie fetid marigold, Roughseed fetid marigold, Boebera chrysanthemoides.

Prairie dogweed displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Prairie dogweed produces small daisy-like flowers in shades of yellow or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Prairie dogweed every 3–5 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.

Prairie dogweed thrives in full sun to partial shade.

Dyssodia papposa tolerates temperatures of 50–85°F. Prairie dogweed prefers humidity levels of 40–70%.

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Prairie dogweed to prevent waterlogging, which leads to root rot and fungal issues.

Feed Prairie dogweed 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 added organic matter for nutrients. Avoid low spots where water collects after rain.

Prairie dogweed 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.

Prairie dogweed can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Prairie dogweed 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.

Prairie dogweed 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.

Prairie dogweed can be propagated through seeds, division of clumps.

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

Prairie dogweed grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Prairie dogweed is native to North America and parts of the Southwest, extending into the Northeast. In cooler regions, grow Prairie dogweed as a houseplant or bring it indoors before the first frost.
