Woodland Stair Plant Care

Woodland Stair (Pterostegia drymarioides) belongs to the Polygonaceae family within the Pterostegia genus. Woodland Stair is also known as Drymaria-like Pterostegia.

Woodland Stair displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Woodland Stair produces small clusters of tiny white or pink flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Woodland Stair 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.

Woodland Stair thrives in full sun to partial shade.

Pterostegia drymarioides tolerates temperatures of 50–80°F. Woodland Stair prefers humidity levels of 40–70%.

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

Feed Woodland Stair 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. Avoid low spots where water collects after rain.

Woodland Stair 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.

Woodland Stair 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 Woodland Stair 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.

Woodland Stair 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.

Woodland Stair can be propagated through seeds, division of clumps.

Woodland Stair 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.

Woodland Stair grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Woodland Stair as a houseplant or bring it indoors before the first frost.
