Broom Snakeweed Plant Care

Broom Snakeweed (Gutierrezia sarothrae) belongs to the Asteraceae family within the Gutierrezia genus. Broom Snakeweed is native to much of the western half of North America, from western Canada to northern Mexico, and can be found in a number of arid, grassland, and mountain habitats. Broom Snakeweed is also known as Matchweed, Broomweed, Solidago sarothrae.

Broom Snakeweed displays an upright, bushy shrub growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Broom Snakeweed produces small yellow flowers in clusters.

Leaf size: approximately 1 inches.

Water a young or newly planted Broom Snakeweed 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.

Broom Snakeweed thrives in full sun.

Gutierrezia sarothrae tolerates temperatures of 50–85°F. Broom Snakeweed prefers humidity levels of 30–60%.

Well-draining sandy soil with some organic matter. Good drainage is essential for Broom Snakeweed to prevent waterlogging, which leads to root rot and fungal issues.

Feed Broom Snakeweed 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 and well-draining sandy soil with some organic matter. Avoid low spots where water collects after rain.

Broom Snakeweed 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.

Broom Snakeweed 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 Broom Snakeweed 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.

Broom Snakeweed 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.

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

Broom Snakeweed 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.

Broom Snakeweed grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Broom Snakeweed is native to much of the western half of North America, from western Canada to northern Mexico, and can be found in a number of arid, grassland, and mountain habitats. In cooler regions, grow Broom Snakeweed as a houseplant or bring it indoors before the first frost.
