Discoloration, wilting, drooping of leaves or branches can be caused by a number of reasons. First you need to identify the problem and apply the appropriate emergency care, then create the best conditions for the cactus to grow for a long time by providing the right soil, light and environment for the plant. .
Steps
Urgent care

Water the cactus with more water. If part of the cactus is shriveled, shriveled, or shriveled (weak or appear limp), the plant probably needs more water. [1] X Research Source If the soil is dry, you need to water it until the water drains out of the bottom of the pot.
- If the soil doesn’t dry out, the problem may be chlorosis, where the rounded or twig-shaped parts of the plant are shriveled up. This is a sign that the plant needs more light, so move the pot to a south- or west-facing window. [2] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/64/Save-a-Dying-Cactus-Step-2-Version-2.jpg/v4-460px-Save-a- Dying-Cactus-Step-2-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/64/Save-a-Dying-Cactus-Step-2- Version-2.jpg/v4-728px-Save-a-Dying-Cactus-Step-2-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Cut off rotting parts of the plant. All brown or black parts of the tree need to be removed. Rotting can be caused by fungi that appear when watering too much. [3] X Source of Study If the soil is soggy, remove the plant and replant it in the right proportions of the soil mix. If the soil is not soggy, you can let the soil dry completely before watering again.
- The standard soil mix for growing desert cactus includes 2 parts garden soil, 2 parts coarse sand, and 1 part peat. [4] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/dc/Save-a-Dying-Cactus-Step-3-Version-2.jpg/v4-460px-Save-a- Dying-Cactus-Step-3-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/dc/Save-a-Dying-Cactus-Step-3- Version-2.jpg/v4-728px-Save-a-Dying-Cactus-Step-3-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Provides extra light for shriveled cactus. Pointed ends in spherical and other round cacti, or shriveled and thin branches in long-branched cacti indicate a condition known as chlorosis. This is caused by a lack of light, so look for a place in your home that gets long periods of light (south-facing windows) or more intense light (west-facing windows). [5] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8c/Save-a-Dying-Cactus-Step-4-Version-2.jpg/v4-460px-Save-a- Dying-Cactus-Step-4-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8c/Save-a-Dying-Cactus-Step-4- Version-2.jpg/v4-728px-Save-a-Dying-Cactus-Step-4-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check for yellowing on the bark. If the bark on the sunny side turns yellow or brown, it means the tree has been exposed to too much sun. You need to move the plant quickly to a cooler place, such as an east-facing window that gets lighter sunlight. [6] X Research Sources
- Wait and see how the cactus reacts when moved to a more shady location. If the yellow parts of the plant do not improve after a few weeks, remove them, leaving only the healthy green parts.

Insect eradication. The main pests that damage cacti are mealybugs and red spiders. Mealybugs are tiny, chalky white and appear in clusters. The red spider is red, relatively small, and has a web like paper between the spines of the cactus. To get rid of both species, you can use a cotton ball soaked in alcohol to clean it and rub it directly on the infected plant. [7] X Research Source You can also use a miticide to get rid of red spiders. [8] X Research Sources
Ensure long-term healthy plant growth

Use the right soil mix. For most desert cactus, a suitable soil mix consists of 2 parts garden soil, 2 parts coarse sand, and 1 part peat. [9] X Research Source The soil mix should be well drained and not harden when dry. [10] X Research Source
- You should also use a clay pot – the weight of the clay pot helps prevent bulky cacti from tipping over; This type of pot also helps to aerate the soil, preventing root rot. [11] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/42/Save-a-Dying-Cactus-Step-7.jpg/v4-460px-Save-a-Dying-Cactus- Step-7.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/42/Save-a-Dying-Cactus-Step-7.jpg/v4-728px-Save- a-Dying-Cactus-Step-7.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Water only when the soil is dry. Test the moisture in the soil by pressing your finger into the topsoil. If the soil is completely dry, water it until the water comes out of the drainage hole in the bottom of the pot. [12] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b2/Save-a-Dying-Cactus-Step-8.jpg/v4-460px-Save-a-Dying-Cactus- Step-8.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b2/Save-a-Dying-Cactus-Step-8.jpg/v4-728px-Save- a-Dying-Cactus-Step-8.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Adjust the watering schedule according to the season. Watering needs for cacti depends on when the plant is growing or hibernating. During the growing season of the plant from March to September, you need to water the plant on average once a month. During the dormant season from October to February, you should only water once a month at most. [13] X Research Source
- Over-watering during the plant’s dormant season is a major cause of cactus problems. [14] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/14/Save-a-Dying-Cactus-Step-9.jpg/v4-460px-Save-a-Dying-Cactus- Step-9.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/14/Save-a-Dying-Cactus-Step-9.jpg/v4-728px-Save- a-Dying-Cactus-Step-9.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Provide enough light. Most succulents need a lot of sunlight. In the summer, you should leave the tree outdoors, being careful not to let it get too much rain. First, put the plant in a shady place first, then gradually move it to a sunny place to prevent it from getting sunburned. [15] X Research Source In the winter, place the pot in a south- or west-facing window, where the sun is the most.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/30/Save-a-Dying-Cactus-Step-10.jpg/v4-460px-Save-a-Dying-Cactus- Step-10.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/30/Save-a-Dying-Cactus-Step-10.jpg/v4-728px-Save- a-Dying-Cactus-Step-10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Monitor the temperature in the room. Cactus likes cool temperatures during hibernation. However, you need to be careful, don’t place the plant in the wind – away from drafty windows and not on the floor near the door. [16] X Research Source The appropriate temperature at night in winter should be between 7 – 16 degrees Celsius, [17] X Research source so a basement or unheated room is a suitable place for storage trees during this period.
- Unless you’re growing cold-tolerant cacti, you should be careful not to let the temperature drop below freezing, as most succulents are not frost-tolerant. [18] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e1/Save-a-Dying-Cactus-Step-11.jpg/v4-460px-Save-a-Dying-Cactus- Step-11.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e1/Save-a-Dying-Cactus-Step-11.jpg/v4-728px-Save- a-Dying-Cactus-Step-11.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Replant the tree according to the growth of the tree. You’ll know when to move the cactus into a larger pot when the top of the plant has grown so heavy that the pot can’t hold it, or when the plant has grown to within 2.5cm of the edge of the pot. [19] X Research source Use a mixture of soil for plants including 2 parts of garden soil, 2 parts of coarse sand and 1 part of peat. [20] X Research Source
- Replant the plant at the same depth as in the old pot.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/3d/Save-a-Dying-Cactus-Step-12.jpg/v4-460px-Save-a-Dying-Cactus- Step-12.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/3d/Save-a-Dying-Cactus-Step-12.jpg/v4-728px-Save- a-Dying-Cactus-Step-12.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Cut off dead roots. A common consequence of over-watering is rotting of plant roots when soaked for too long in wet soil with poor drainage. Before replanting the plant, gently brush off the soil on the roots after removing the root ball from the soil in the old pot. Examine the roots and trim away any shriveled black roots or dry roots that appear dead. Cut just to the point where the roots are still alive. [21] X Research Source
- You can avoid root rot by growing the plant in a pot with drainage holes and not allowing water to sit in a drip tray at the bottom of the pot. [22] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f4/Save-a-Dying-Cactus-Step-13.jpg/v4-460px-Save-a-Dying-Cactus- Step-13.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f4/Save-a-Dying-Cactus-Step-13.jpg/v4-728px-Save- a-Dying-Cactus-Step-13.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Do not rush to replant as soon as the roots are damaged. If the roots are damaged when you remove the cactus from the old pot or need to prune dead roots, leave the plant outside for about 10 days. This will give the tree time to form scars around the cut or damaged parts. You should put the plant on a sheet of paper, in a place where there is no sunlight but not too cool. [23] X Research Sources
- The cactus will grow best after replanting if you do this during the growing season (March to September). [24] X Research Source
- Typically, most cacti need to be replanted every one to two years. [25] X Research Sources

Use a fertilizer with a low nitrogen content. Most fertilizers have numbers showing the percentages of nitrogen, phosphorus and potassium in the fertilizer (in the form: N-Ph.-Po.) An example of a fertilizer with a nitrogen content A suitable fertilizer for cacti is a 10-30-20 fertilizer, in which the nitrogen content is 10. [26] X Research source
- Too much nitrogen will cause the cactus to have a soft texture, inhibiting the growth of the plant. [27] X Research Source
- Cactus should never be fertilized during the plant’s dormant season (October to February). [28] X Research Sources

Wash off dirt. Photosynthetic ability of the tree will be reduced if the bark is covered with dirt. [29] X Source of study You should use a rag or sponge dipped in a solution of water mixed with a drop of dishwashing liquid to clean the dirt on the tree, then rinse it under the tap or use a sponge soaked in water to clean it.
