Tetraena giessii Plant Care

Tetraena giessii (Tetraena giessii) belongs to the Zygophyllaceae family within the Tetraena genus. Tetraena giessii is native to Namibia.

Tetraena giessii displays a low, spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Tetraena giessii produces small, star-shaped yellow flowers.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Tetraena giessii every 14–21 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.

Tetraena giessii thrives in full sun.

Tetraena giessii tolerates temperatures of 50–90°F. Tetraena giessii prefers humidity levels of 30–60%.

Sandy, well-draining soil mix with gravel and limestone for good drainage. Good drainage is essential for Tetraena giessii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Tetraena giessii 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 sandy, well-draining soil mix with gravel and limestone for good drainage. Avoid low spots where water collects after rain.

Tetraena giessii 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.

Tetraena giessii can spread to about 2 ft (0.6 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Tetraena giessii 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.

Tetraena giessii 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.

Tetraena giessii can be propagated through seeds, stem cuttings.

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

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