Haworthia Cooperi Plants Care

Size & Growth

The Haworthia Cooperi plant is a slow-growing succulent producing clumps of small rosettes of fleshy, tiny green leaves.

It grows up to 2” inches long. The short stem of this plant sprouts variegated leaves that almost reach the soil surface.

The stems of Haworthia Cooperi have transparent tips enabling light to pass.

Flowering and Fragrance

The blooming time of this plant is in summer and spring.

The inflorescence of white-colored flowers grows on a peduncle, growing up to 12” inches.

Light & Temperature

Haworthia Cooperi prefers to sit in bright light but doesn’t like direct full sun.

When this plant is growing in its native environment, it’s mostly situated under the shade of a tree, rock, or other objects.

It is best to place this plant on a windowsill facing west or east to get bright light for at least three to four hours during the day. Good results are obtained by giving plants morning sun exposure.

The Haworthia Cooperi prefers the warm temperatures during the summer but also grows well in the cooler temperature down around 50° degrees Fahrenheit (10° C).

The temperature should not be below 40° degrees Fahrenheit (4° C) as this results in a freezing injury.

The hardiness zones of this plant are 9 – 11.

Haworthia Cooperi Watering and Feeding

During the summer season, water cooperi Haworthia generously and evenly. Make sure to allow the soil to dry completely between watering.

During the winter season, decrease the amount of water to once a month.

Make sure there is no amount of water gathered around the rosette.

Feed this plant using a succulent fertilizer in the summer season, but never feed it in the winter.

Soil & Transplanting

When growing Haworthia cooperi utilize a quick-draining succulent potting soil mix and a pot with a drainage hole for this plant.

Avoid including sand in the soil mixture as this ends up clogging the pores, decreasing the drainage.

Mix the soil with pumice, aquarium gravel, or perlite.

Grooming and Maintenance

Haworthia Cooperi is not a tricky houseplant to take care of with similar requirements of an Aloe.

Similar to all succulent plants, the main thing to watch out for is overwatering.

Make sure this plant never sits in too much water for prolong duration as this can cause damage to the roots.

If the container doesn’t have a sufficient drainage system, including a gravel layer at the bottom of the container.

In case the plant grows yellow or white leaves, it is a sign of too much sun.

On the other hand, the green color of the Haworthia cooperi leaves starts to fade, the plant isn’t getting sufficient light.

When transferring the indoor plant outside during the warm season, be sure to do this gradually to avoid sunburn.
