Blue Haworthia Plant Care

Blue Haworthia (Haworthiopsis glauca) belongs to the Asphodelaceae family within the Haworthiopsis genus. Blue Haworthia is also known as Glaucous Haworthia.

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

Leaf size: approximately 3 inches.

Water a young or newly planted Blue 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.

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

Haworthiopsis glauca tolerates temperatures of 50–80°F. Blue Haworthia prefers humidity levels of 30–60%.

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

Feed Blue 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.

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.

Blue Haworthia 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.

Blue 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 Blue 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.

Blue Haworthia 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.

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

Blue 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.

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