What to Do After Haworthia Cooperi Withers? The Latest Treatment Methods

Haworthia cooperi is currently one of the most popular small succulents in China. The main reason for its popularity lies in its crystal-clear leaves, which are transparent or semi-transparent, like jelly, and very cute. Many people who have grown Haworthia cooperi have mentioned that their Haworthia cooperi leaves gradually shriveled as they cared for them, especially the bottom leaves, which is particularly obvious. What is going on? Qinnongwang will now guide everyone to understand: the causes of Haworthia cooperi shriveling and the recovery methods.

1. Causes of Haworthia cooperi Leaf Shriveling

1. Poor root development

If a newly acquired Haworthia cooperi develops shriveling as it is being grown, the first thing to consider is whether the roots have not developed well. Since the roots cannot absorb nutrients from the soil, Haworthia cooperi will rely on the nutrients in its leaves to sustain itself, thus causing the leaves to shrivel. If during cultivation you find that Haworthia cooperi has not grown for a long time and its leaves have shriveled, you can consider digging it out and changing the soil for cultivation.

2. Light

Haworthia cooperi likes a cool, bright light environment. If the temperature is too hot and Haworthia cooperi remains in an environment with strong light exposure, then leaf shriveling may occur.

3. Humidity

Many forums have introduced the method of enclosed cultivation for Haworthia cooperi. Enclosed cultivation of Haworthia cooperi is actually a care method that provides a high-humidity environment for it. Haworthia cooperi grown in a higher-humidity environment will have more dewy, plump leaves. If the environment where Haworthia cooperi grows is too dry and moisture cannot reach the leaves, leaf shriveling is likely to occur.

4. Waterlogging

Haworthia cooperi is a shallow-rooted plant, so during cultivation it does not need a very deep pot, and the soil should also be loose and well-draining. During watering, prevent waterlogging, because if the potting soil becomes waterlogged, Haworthia cooperi is prone to root rot, the leaves cannot absorb nutrients, they shrink, and then dry up and die.

5. Rain exposure

Haworthia cooperi leaves are crystal-clear and plump, but this does not mean Haworthia cooperi can withstand rain exposure, because after rain, rainwater will slide down along the leaves and gather at the roots, creating a waterlogged situation at the roots and easily leading to root rot.

6. Frost damage

Haworthia cooperi likes cool shade, but it is not cold-tolerant. Haworthia cooperi grown indoors in winter will suffer frost damage due to low nighttime temperatures, and after frost damage, Haworthia cooperi will show leaf shriveling.

2. How to Handle Haworthia cooperi After It Shrivels

There are many causes of Haworthia cooperi shriveling, so the treatment methods after discovering Haworthia cooperi shriveling are also different. Qinnongwang summarizes the main methods as follows:

1. For leaf shriveling caused by root rot after overwatering or rain exposure, you can directly dig out the plant and replace the potting soil to replant it. The newly replaced potting soil only needs to be slightly moist. The rotted root parts must be completely removed. You can also peel away some of the skin at the root area to expose the stem of the plant. The shriveled leaves also need to be cut off to prevent them from continuing to absorb nutrients, and then wait quietly for the plant to regrow roots.

2. For leaf shriveling caused by frost damage, the shriveled leaves also need to be cut off for the same reason as above, and then the plant should be placed in a sunny spot to bask, preferably behind a screen window or tinted glass, because burns caused by direct strong light also need to be avoided.

3. The Growing Environment of Haworthia cooperi

Haworthia cooperi is suitable for growing in a semi-shaded environment and likes cool conditions. Its main growing season is the cool spring and autumn seasons. It needs a certain amount of air humidity, is drought-tolerant but not tolerant of drought, and in summer it must not be directly exposed to the sun, nor placed in prolonged shade. The specific environmental requirements are as follows.

1. Temperature: Haworthia cooperi originated in the warm, dry environment of South Africa. The suitable temperature for growth is 18-22°C. During the high-temperature period in summer, Haworthia cooperi is in a semi-dormant or dormant state and grows slowly, and can be placed in a ventilated, cool area for care. In winter, if the nighttime temperature is above 8°C and the daytime temperature is above 20°C, it can grow normally. It can tolerate a short-term low temperature of 0°C, but there will be obvious frostbite marks on the leaves. During overwintering, it is advisable to keep the temperature above 5°C.

2. Light: Haworthia cooperi is relatively sensitive to light. Too strong light will cause poor leaf growth, turning light reddish-brown, and may even burn the leaves; too much shade will cause the Haworthia cooperi plant shape to become loose and not compact, with thin, elongated leaves. The care method is to add a layer of shade netting in summer, and remove the shade netting from after autumn to the following spring.

3. Soil: Haworthia cooperi is suitable for growing in loose, well-draining sandy soil. It is commonly planted in a mixed soil of 2 parts leaf mold and 3 parts coarse sand or vermiculite, mixed with a small amount of bone meal, etc. The organic matter content of the soil should be appropriately increased.

4. Watering: During the growing season, watering should follow the principle of “do not water until dry, and water thoroughly when watering.” There must be no waterlogging, and even less rain exposure, to avoid root rot. The drought period should not be too long. Although Haworthia cooperi is drought-tolerant, long-term water shortage will cause the leaves to shrivel. When the air is dry, water can be supplied by spraying.

Fertilizing: During the growing season, vigorously growing plants can be given a decomposed dilute liquid fertilizer or a low-nitrogen, high-phosphorus-potassium compound fertilizer once a month. Newly planted plants or weaker-growing plants do not need fertilizing. When temperatures are lower in summer and winter, Haworthia cooperi is in a dormant period, and fertilizing is also unnecessary at this time. The fertilizing time is usually on a clear morning or evening.

The above is what Qinnongwang introduces regarding the causes of Haworthia cooperi leaf shriveling and the corresponding measures. The leaves are the main ornamental part of Haworthia cooperi. Once shriveling occurs, it will greatly affect the value of Haworthia cooperi. We hope this article can provide some reference value for fellow flower lovers.
