Creosote bush Plant Care

Creosote bush (Zygophyllum dumosum) belongs to the Zygophyllaceae family within the Zygophyllum genus. Creosote bush is native to Egypt, the Sinai Peninsula, and the Levant. Creosote bush is also known as white brittlebush.

Creosote bush displays a low spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 3 ft. Creosote bush produces small, star-shaped flowers in shades of white, yellow, or pink.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Creosote bush 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.

Creosote bush thrives in full sun to partial shade.

Zygophyllum dumosum tolerates temperatures of 50–90°F. Creosote bush prefers humidity levels of 30–60%.

Sandy, well-draining soil with low to moderate fertility, such as a mix of sand, loam, and gravel. Good drainage is essential for Creosote bush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Creosote bush 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and sandy, well-draining soil with low to moderate fertility, such as a mix of sand, loam, and gravel. Avoid low spots where water collects after rain.

Creosote bush is suited to USDA Zone 9a – 11b.

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.

Creosote bush can spread to about 3 ft (0.9 m) and reach about 2 ft (0 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 Creosote bush 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.

Creosote bush is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Creosote bush can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to white bean-caper plant care, which shares the same genus.

Creosote bush 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.

Creosote bush grows outdoors in USDA Zone 9a – 11b. It survives winters down to planting zone 9a. Creosote bush is native to Egypt, the Sinai Peninsula, and the Levant. In cooler regions, grow Creosote bush as a houseplant or bring it indoors before the first frost.
