Reinwardt's Haworthia Plant Care

Reinwardt's Haworthia (Haworthiopsis reinwardtii) belongs to the Asphodelaceae family within the Haworthiopsis genus. Reinwardt's Haworthia is native to the Eastern Cape Province of South Africa. Reinwardt's Haworthia is also known as Zebra Wart Plant.

Reinwardt's Haworthia displays a low rosette, clumping growth habit, reaching up to 0.5 ft tall with a spread of approximately 0.5 ft. Reinwardt's Haworthia produces small tubular white or pink flowers on tall stalks.

Leaf size: approximately 3 inches.

Water a young or newly planted Reinwardt's Haworthia 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.

Reinwardt's Haworthia thrives in bright indirect to partial sun. Avoid placing Reinwardt's Haworthia in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Haworthiopsis reinwardtii tolerates temperatures of 50–80°F. Reinwardt's Haworthia prefers humidity levels of 30–60%.

Well-draining succulent mix with perlite and coarse sand. Good drainage is essential for Reinwardt's Haworthia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Reinwardt's Haworthia every 8 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 bright indirect to partial sun and well-draining succulent mix with perlite and coarse sand. Avoid low spots where water collects after rain.

Reinwardt's Haworthia is suited to USDA Zone 9b – 11.

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.

Reinwardt's Haworthia can spread to about 1 ft (0.2 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Reinwardt's Haworthia 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.

Reinwardt's Haworthia 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.

Reinwardt's Haworthia can be propagated through offsets, leaf cuttings. Similar propagation techniques also apply to zebra haworthia plant care, which shares the same genus.

Reinwardt's Haworthia is susceptible to spider mites, mealybugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Reinwardt's Haworthia grows outdoors in USDA Zone 9b – 11. It survives winters down to planting zone 9b. Reinwardt's Haworthia is native to the Eastern Cape Province of South Africa. In cooler regions, grow Reinwardt's Haworthia as a houseplant or bring it indoors before the first frost.
