Haworthia Cuspidata Summary

Haworthia Cuspidata Physical Characteristics

It forms rosettes of lime-green leaves. The leaves are wedge-shaped with a pointy tip which is a translucent area. The translucent section of the leaf allows the sun’s rays to get into the thick leaf and support photosynthesis. These leaves form a star-like rosette, another feature from which this plant gets its name. It is stemless, and the rosette forms in concentric rings.

Haworthia Cuspidata Care

This is an excellent plant to the pot and keeps indoors; it is small enough to keep on the window sill or desktop. It can use water from one drink for a long time as a succulent before requiring another. Allow the soil to dry out before watering again, like when you use the soak-and-dry method.

Keeping it under indirect sunlight or full shade works well with it. Adequate lighting is essential for its survival and quality. Also, poor lighting may affect the color of the foliage. This succulent is not cold hardy but can survive up to -1oC for a short time. However, it appears able to withstand outdoor winter rain quite well,

You can give it some fertilizer a few times in the growing season. The fertilizer should be a slow-release general-purpose fertilizer. Avoid feeding the plant too much nitrogen because it makes succulent leaves too watery and soggy. While properly used, the fertilizer enhances the plant’s foliage, flowers, and general health.

The substrate in which you grow the plant should be very well drained but moisture retentive. It prevents water logging and therefore saves your plant from root rot.  A 50:50 mix between loamy soil and gravel will work. However, you can buy a commercial cactus mix to grow it in.

DO YOU KNOW? Caring (propagating, pruning/trimming, beheading, watering, …) is a set of skills that is widely applicable to succulents. Read the in-depth guide here >>

Haworthia Cuspidata Growth

This plant produces offsets prolifically, an ideal medium for propagation. Also, you can propagate it using leaf cutting. Viable seeds are rare.  Leaf cuttings take a little longer to get established as a plant than succulents, but you get there eventually.

It usually doesn’t need pruning except when you are looking for an offset or leaf cutting to propagate. Repotting is also rare because it is small and slow-growing. The main way to get the plant sick is by overwatering. Mealybugs, scale insects, and root insects are the primary pests.
