Haworthia Cooperi Summary

Haworthia Cooperi’s Physical Characteristics

The succulent’s main distinguishing feature is a slow-growing plant with a short stem that produces numerous leaves that form rosettes. Its leaves are thick and very watery. They are light green but have veins with an even lighter shade of green crossing the surface. These leaves have a vertical orientation but are recurved. The end of the leaf usually has a long bristle, a more extended version of the leaf’s bristles that populate the margin. It has a transparent window at the tip, another characteristic of this genus plant.

It has contracting roots that pull below the surface. It grows below the surface, especially as the climate gets hotter. Only the translucent tips will be visible in such instances.

Haworthia Cooperi’s Care

It is a slow-growing plant with offsets. It can use water from one drink for a long time as a succulent before requiring another. Keep the soil moist throughout summer but allow the soil to dry out before watering again in winter.

It would help if you kept it under indirect sunlight because it grows in a similar wild environment. After all, there is usually a canopy of bushes above it. Adequate lighting is essential for its survival and quality. Also, poor may affect the color of the foliage. Also, note that it is susceptible to scorching when the sun’s rays are too intense.

You can give it some fertilizer only once 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 adequately 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 Cooperi’s Growth

This plant is solitary and, therefore, doesn’t produce offsets. You will, therefore, only be able to propagate it using leaf cuttings or seeds. Leaf cuttings take a little longer to get established as a plant. On the other hand, seeds overgrow, and their path to establishment is more straightforward.

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