What to Do When a Cactus Has Root Rot? A Detailed Guide to the Latest Treatment Methods
The cactus is a plant we are all very familiar with, and it is also a plant with a relatively wide growing range. The cactus has always given people the impression of having tenacious vitality, but did you know that if it is not cultivated properly, the cactus is also very likely to develop root rot. So what causes cactus root rot? What should you do when a cactus has root rot? Let us take a look together.
1. Causes of Cactus Root Rot
In fact, the cactus really is a plant with relatively tenacious vitality. Under normal circumstances, as long as it is cultivated properly, it generally will not have any problems. Therefore, if a cactus develops root rot, it is very likely that it has been affected by disease. Let us take a closer look at what causes cactus root rot.
1. Viral infection
This is caused by viruses, fungi and the like contained in the environment where the cactus is routinely cared for. For example, if the soil, water and fertilizer are not kept clean, pathogens multiply in large numbers in the soil and other environments, attacking the roots and stems of the cactus, which can lead to the rotting of the cactus roots.
2. Improper care
Improper care is caused by not understanding the growth habits of the cactus. If it is watered too much, the potting soil becomes too wet, or there is even standing water in the soil, it is very easy to cause root rot; next is excessive fertilizing. When fertilizing, applying too much nitrogen fertilizer or applying fertilizer that has not been fully decomposed will cause the plant's roots to burn, and thus the roots will rot; finally, there is excessive shading. The cactus can live in deserts, so it is very drought-tolerant. Shading instead causes the plant to be unable to absorb sunlight, resulting in poor development. At the same time, sunlight also has a disinfecting effect. Insufficient sunlight makes it more susceptible to pests and diseases, leading to root rot.
2. Ways to Handle Cactus Root Rot
Once you find that a plant has been infected by disease or has root rot or stem rot, it must be cut away promptly to prevent the infection from spreading to other parts. After that, apply plant ash to the wound or soak it in potassium permanganate solution. You can also simply place the cactus in a ventilated place to let the wound dry.
3. Daily Care Methods for Cactus
1. Water reasonably to prevent standing water in the potting soil or excessive moisture, because dampness causes root and stem rot;
2. The cactus prefers an environment with ample light, but be careful not to expose it to harsh sun. At the hottest time at noon in summer, it should be shaded appropriately;
3. In the cold winter season, it should be placed in a spot with light, not in a dark corner, and it should be kept well ventilated to reduce attacks by disease.
4. Fertilize at the right time and in the right amount. During the growing period, fertilizing once every half month is enough. In autumn, control the amount of fertilizer, and after winter you can stop fertilizing. The concentration of the fertilizer should be low, and it can be diluted with water before applying. In this way, root and stem rot will not occur.
The above is the information Qinnong Net has collected for everyone on how to handle cactus root rot. What do you think? In fact, the cactus itself is a plant that is relatively easy to keep alive. If the root rot is truly too horrible to look at, but the above-ground part still has healthy parts, we can choose a section that is in relatively good growing condition, cut it off, and replant it as a cutting in soil. Sometimes this can also save the cactus's life!
