Hello, cactus is a relatively drought-resistant plant, and most cacti turn yellow because of overwatering. Cacti do not have such high water requirements, so when watering too much, you need to immediately move to a particularly ventilated place.
If it is still serious, it will need to be re-potted. Or if it rains too much in summer, its leaves will soften and rot. If the rot is not serious, cut off the rotten part of it in time, soak carbendazim to dry the wound, and then re-cutting.
The reason for the softness may be because the root system is not strong enough, we have to put it in a place with sufficient sunlight, so that the light is particularly sufficient, and the root system of the cactus is naturally particularly developed.
If you pay attention to observation, you will find that not only the leaves are thin and long, but the thorns are also thin and long, and they are soft, and they are not very powerful. The cactus thorns that grow outdoors or in the wild are not long, but they are very hard, and it hurts to prick people, and they can prick you if they are touched.

When the roots of the cactus are yellow and soft, you need to cut off the soft place with a blade in time, and then keep the cactus in the moist soil, and spray water mist around the plant to moisturize, and often spray insecticides to prevent and control insect pests, if the fertilizer is too much, you should irrigate the cactus in time to wash away the excess fertilizer.
1. Reduce moisture
The yellowing and softening of the roots of the cactus bulb may be caused by overwatering, at this time it is necessary to cut off the softened place, and then place the ball in a cool and ventilated place to dry, and then the cactus ball is maintained in moist soil, and can not be watered, you can spray water mist around the plant, and soon the oak can be bred into a new sphere.
2. Reduce light
The yellowing and softening of the roots of the cactus bulb may be caused by the lack of water due to the exposure to the sun during the long period, so the plant needs to be moved to a cool place indoors for maintenance, and it can be watered once a week.
3. Eliminate insect pests
During the maintenance of the cactus, it is necessary to pay attention to the prevention and control of pests and diseases, otherwise the roots will be yellowed and soft after being eroded by the pests, and it is necessary to use insecticides to spray in time to avoid harming the whole plant.
4. Irrigation and fertilization
Too much inorganic fertilizer applied to the cactus will cause fertilizer damage, which will cause the roots to turn yellow and soft, at this time, it is necessary to irrigate the plant in time and flush the fertilizer, and discharge the excess water to avoid root rot.

What should I do if the cactus ball becomes soft?
1.Rotten roots: Sometimes cacti are prone to rot due to excessive watering, damp potting soil, and poor ventilation, some from the bottom and some from the core. We can check it, gently lift the cactus ball up, and see if the bucket is still strong without roots, generally if it is a rotten problem, you can see it at this time.
If the rot is very serious, more than the sphere 1 3, it is generally irretrievable, unless it is rotten from the side, and there is still healthy tissue in the root disc part, in this case, even if the rotten is a little more serious, it can continue to be saved.
The rescue method is very simple, cut off the rotten part, then sprinkle with plant ash or carbendazim and the like, put it in a cool and ventilated place to dry, and when the wound scabs over, replant the empty mold and plant.
2.The cactus becomes soft due to lack of water.
Although the cactus is more drought tolerant, but if there is an extreme lack of water, the cactus will appear in a state of self-protection, the ball will become soft, and even wrinkles are normal, we only need to water normally at this time, and the subsequent cactus will recover itself, if there is no recovery, it is recommended to repair the roots and replant.
If your balls have been raised for a long time, and the roots are always yellow, and there is no rot, then you don't have to worry at all. This is the normal growth and aging of cactus. You must know that many cactus balls are now grafted by profiteers in order to get bigger, and the balls that fall to the ground in this way age very quickly. >>>More
