The long wait is over! Below, we will provide you the Haworthia cooperi care tips and explain all necessary details.
When raising a Haworthia cooperi in a pot, use a succulent potting soil mix that drains quickly. However, if you don’t have any cacti mix on hand, you can always make your own soil mixture. That’s an easy task to do anyway.
The process is easy: combine equal parts of “normal” potting soil, perlite, and coarse sand. Because Haworthia cooperi does not tolerate wet soil, this mixture will provide the best drainage properties.
Water cooperi moderately and evenly during the summer months. Do this especially during the growing season of the plant. Make sure the soil is parched in between waterings. Excess water must be well-drained.
Because this plant is drought-tolerant, don’t be concerned if you forget to water it for a few days. Reduce the frequency of watering to just once a month throughout the winter. The plant is dormant and will not require much water.
Pro tip: Avoid using cold water to avoid stressing the plant. Instead, use lukewarm water or one having room temperature.
Haworthia cooperi loves bright light but avoids the full sun. When growing in its natural habitat, this plant prefers to be in the partial shade of a tree, rock, or other objects. Treat the plant in the same way when planted outdoors.
If grown indoors, place them near an East-facing window if possible. This is ideal since there will be some direct sunlight in the morning with low intensity. Plus, your Haworthia cooperi plants will receive just the perfect quantity of indirect light for the rest of the day.
This succulent enjoys being in warm weather in the summer. However, it can also thrive in temperatures as low as 50oF (10oC). A freezing injury can occur if the temperature falls below 40oF (4 oC).
Bear in mind that the goal is to achieve consistency. Depending on the case, everything lower or higher can be harmful to this wonderful succulent, specifically if exposed to these conditions for a long time.
We suggest that you keep watch and prepare for the changing temperatures. It helps to have a thermometer ready at home so you could monitor.
There are no specific humidity needs for Haworthia cooperi plants. You don’t need to mist the fleshy leaves if your house has an average humidity level. Always remember that the plant’s growth might be hampered by high humidity, cold weather, and over-watering. So keep these things in moderation.
It’s critical to pay attention to airflow when growing Haworthia cooperi indoors. Healthy succulent development necessitates good air circulation. Proper ventilation allows moisture to drain more quickly and lowering the danger of root rot.
Fertilizer is not that needed for plant Haworthia cooperi. They are not heavy feeders. It only consumes a few amounts of nutrients and does so slowly. You can entirely avoid using fertilizer without hurting the plant.
However, to stimulate healthy growth, you need to feed once or twice a year – during fall and spring. A succulent or cactus fertilizer is just perfect. Before using, always dilute the fertilizer to half strength.
Pro tip: Chemical (artificial) fertilizers should be avoided because they are too strong for succulents.
If you want to naturally propagate your Haworthia cooperi, this offset method is right for you. Around the base of the mother plant, it produces offsets or “pups.” These offsets are ideal for vegetative propagation which is a relatively simple process.
Gently separate these mini succulents from the main plant to propagate. Allow drying for 1-2 days outside in filtered sunlight till the offset callous ends. Before watering, give it a week. After that, you may plant them in a tiny pot with the necessary potting soil.
The plants will take root after a few weeks. It’s best to place it near a bright indirect, well-ventilated window indoors and water it every two weeks. And there you have it! Your new Haworthia cooperi plant.
In USDA hardiness zones 9 and 10, Haworthia cooperi is considered sturdy. It prefers to be kept warm throughout the year, much as it would be in its native home in South Africa. You may grow this plant outside all year if you live in this suitable climate.
In shallow pots, Haworthia cooperi does well. If you’d like to put it in a larger container, fill the bottom half of the pot with pebbles or gravel before adding fresh soil. They can easily be placed in attractive containers like a teacup or pottery bowl. Always make sure there is adequate drainage.
On the other hand, Haworthia cooperi plants don’t overgrow. Thus they don’t outgrow their pots very often. They shouldn’t need to be re-potted very often throughout their lives, but it’s a good idea to do it every few years to have fresh soil.
As easy-going as this plant appears, there’s a good possibility you won’t need to set up elaborate grooming and maintenance. When it comes to pruning, you may only need to remove the dead translucent leaves.
Apart from that, keep it in bright indirect light to prevent the leaves from turning pale. The damaged leaves simply look horrible, even if there are only a few of them. But don’t turn a blind eye because they could quickly put the entire plant in jeopardy!

Haworthia cooperi var. Picturata

Haworthia cooperi Diseases & Pests
Proper care for Haworthia cooperi also involves looking out for some pests and diseases. Although Haworthia is mainly pest-free, a few can harm your plant and cause root and leaf rot.
- Mealybug infestations can be dealt with using insecticides. Another is to combat fungus gnat infestations (whose larvae feed on roots), remove the plant from its growing container. Then soak it in a one percent hydrogen peroxide solution for 15 minutes.
- Root rot, caused by poor drainage, is the most prevalent disease that affects the growing succulent Haworthia. Leaf rot and withering may result as a result of this disease. Root rot can be treated by removing rotted roots, allowing the plant to heal and create a callus at the defect area, and then repotting the plant.
Frequently Asked Questions
Why is my Haworthia cooperi shriveling?
The shriveling of your Cooper’s haworthia can be caused by too much or too little water. It’s easy to figure out which one happened in your situation. Simply look at the soil. If it’s soggy, it’s due to overwatering. If it’s not, it’s due to dehydration.
What to do if succulent leaves are wrinkled?
Succulents can become wrinkled due to a variety of circumstances. Underwatering, overwatering, a lack of or excessive light exposure, and not having well-draining soil that can promote root rot are the most prevalent causes. That said, if you observe succulents turning wrinkly, it is a good idea to evaluate which of the reasons stated can cause the issue.
Why is my Haworthia cooperi stretching?
Your plant is most likely etiolated. This means that it has stretched out due to a lack of light. Even though this isn’t one of the most light-loving succulents, it still has to be placed in front of a window to keep compact.
