What to Do If a Cactus Has Root Rot? Teach You the Correct Way to Handle It

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 cultivated improperly, a cactus is also very likely to develop root rot? So what are the causes of cactus root rot? What should be done about cactus root rot? Let us take a look together.

I. 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 to have been invaded by disease. Let us take a specific look below at what causes cactus root rot.

1. Viral infection

This is caused by viruses, fungi and so on contained in the environment of the cactus's daily care. For example, if the soil, water and fertilizer, etc. are not kept clean, pathogens multiply in large numbers in the soil and other environments and invade the cactus's roots and stems, which may cause the cactus's roots to rot.

2. Improper care

Improper care is caused by not understanding the cactus's growth habits. If too much water is given, when the potting soil is too wet or there is even standing water in the soil, it is very easy to cause root rot; second is excessive fertilizing. When fertilizing, applying too much nitrogen fertilizer or applying fertilizer that has not been decomposed will cause the plant's roots to burn, and thus the roots will rot; finally, excessive shading. Cacti can live in deserts, so they are 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 sterilizing effect. Insufficient sunlight makes it more susceptible to invasion by pests and diseases, thus leading to root rot.

II. Treatment Methods for Cactus Root Rot

Once it is found that a plant has been infected by pathogens or has root rot or stem rot, it should be pruned away in time to prevent infection of other parts. After that, apply plant ash to the wound or soak it in potassium permanganate solution. It is also fine to directly place the cactus in a ventilated place to let the wound dry.

III. Daily Care Methods for Cacti

1. Water reasonably to prevent water accumulation in the potting soil or excessive moisture, because dampness causes root rot and stem rot;

2. Cacti prefer an environment with sufficient light, but be careful not to expose them to the scorching sun. At the hottest time around noon in summer, they should be properly shaded;

3. In the cold winter season, place them in a place with light. Do not put them in a dark corner. Pay attention to frequent and good ventilation to reduce invasion by pathogens.

4. Fertilize at the right time and in the right amount. During the growth period, fertilizing once every half month is enough. In autumn, control the amount of fertilizing. After winter, fertilizing can be stopped. The concentration of the fertilizer should be low, and it can be diluted with water before applying. In this way, root rot and stem rot will not be caused.

The above is the handling methods for cactus root rot collected by Qinnong Web for everyone. What do you think? In fact, the cactus itself is a plant that is relatively easy to keep alive. If the roots have rotted so badly that it is simply too awful to look at, but the aboveground part still has healthy parts, we can choose a section that is in relatively good growing condition, cut it off and replant it in soil as a cutting. Sometimes this can also save the cactus's life!
