Wall Whitlow-grass Plant Care

Wall Whitlow-grass (Draba muralis) belongs to the Brassicaceae family within the Draba genus. Wall Whitlow-grass is native to southern, central and northern Europe, northwestern Africa, Turkey, Crimea, and the Caucasus.

Wall Whitlow-grass displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Wall Whitlow-grass produces small white or yellow flowers in clusters.

Leaf size: approximately 1 inches.

Water a young or newly planted Wall Whitlow-grass every 7–10 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.

Wall Whitlow-grass thrives in full sun to partial shade.

Draba muralis tolerates temperatures of 50–75°F. Wall Whitlow-grass prefers humidity levels of 40–60%.

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

Feed Wall Whitlow-grass 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 well-draining sandy soil with some organic matter. Avoid low spots where water collects after rain.

Wall Whitlow-grass is suited to USDA Zone 6a – 9b.

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.

Wall Whitlow-grass can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Wall Whitlow-grass 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.

Wall Whitlow-grass is hardy down to USDA zone 6a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Wall Whitlow-grass can be propagated through seeds, division. Similar propagation techniques also apply to magellan draba plant care, which shares the same genus.

Wall Whitlow-grass is susceptible to aphids, flea beetles, cabbage worms. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Wall Whitlow-grass grows outdoors in USDA Zone 6a – 9b. It survives winters down to planting zone 6a. Wall Whitlow-grass is native to southern, central and northern Europe, northwestern Africa, Turkey, Crimea, and the Caucasus.
