Plant Crowded haworthia in bright indirect to partial sun (USDA zones 10b–12b) and water a young shrub every 14–21 days until it is established. It tolerates temperatures of 50–80°F (10–27°C). Fertilize it every 8 months during the growing season.

What Is the Crowded haworthia?

Crowded haworthia (Haworthiopsis coarctata) belongs to the Asphodelaceae family within the Haworthiopsis genus. Crowded haworthia is also known as Stripey Aloe, Ox-tongue Aloe.

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

Leaf size: approximately 3 inches.

How Often Should You Water a Crowded haworthia?

Water a young or newly planted Crowded 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.

What Soil Mix Works Best for a Crowded haworthia?

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

How Often Should You Fertilize a Crowded haworthia?

Feed Crowded 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.

Where Should You Plant a Crowded haworthia?

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.

Crowded haworthia is suited to USDA Zone 10b – 12b.

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.

How Far Apart Should You Plant a Crowded haworthia?

Crowded 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.

How Do You Prune a Crowded haworthia?

Prune Crowded 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.

How Do You Care for a Crowded haworthia in Winter?

Crowded haworthia is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

How Do You Propagate a Crowded haworthia?

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