What Soil Mix Works Best for a Window Haworthia?

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

How Often Should You Fertilize a Window Haworthia?

Feed Window 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 Window 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.

Window 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.

How Far Apart Should You Plant a Window Haworthia?

Window 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 Window Haworthia?

Prune Window 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 Window Haworthia in Winter?

Window 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.

How Do You Propagate a Window Haworthia?

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