The cactus is rotten! Why do cacti rot?

Cactus should not be watered too often. Otherwise, it's the most perishable.

And the sun must be sufficient, so that it can grow well. The plant type will also be beautiful. If you don't get sunlight for a long time, it will rot from the roots...

In your case, cut off the rotten part and then put the wound in the sun until it heals, and then plant it back in the pot to ensure that the potting soil is moist, and then don't water it first, and water it normally after a month. Be sure to keep it in a sunny place...

After you leave it to dry for a few days, and when the wound is dry, you can put it in moist soil, and it won't be long before the roots will grow

Dry it, don't let it rain after planting, put it in a sunny place, and it will be fine soon.

Improper watering during the breeding process, if the cactus is overwatered in the daily breeding process, it will cause root rot.

Root rot caused by pests and diseases: The rot of cactus balls is most likely caused by bacterial infection, as well as the tools used for reproduction, there are pathogenic bacteria and fungi, if we do not pay attention to disinfection and sterilization, germs can easily multiply in the soil and environment and harm plants.

Wounds caused by propagation, wounds caused by pest gnawing, epidermal paraphrasing of seedlings, and the lower part of the stem of the formed plant are often the "shortcuts" for pathogens to invade the plantWhen environmental conditions are conducive to the proliferation of pathogens, plants, especially seedlings, often die rapidly in batches.

Cactus decay - caused by staining.

Cacti can rot, which may be the cause of staining. Many of the cacti on the market are colorful and look beautiful, but most of them are artificially dyed to show such a bright color. It doesn't take long for flower lovers to notice that the whole sphere has become soft, the inside has become black, and in severe cases, it will emit a foul smell.

This is mainly because dyed cacti will contain a lot of chemical components. When watering, chemicals can easily seep into the cactus with the water, causing it to rot.

Cactus rot – improper watering.

If the cactus is not stained, but it is still messy, this is probably the reason for watering. Too much water when watering, or dripping from the tip of a cactus when watering, can easily cause the ball to rot. Then we need to take measures in time.

First of all, when watering, be careful to pour water into the soil, not on the sphere. Secondly, if there is rot on the ball, if the rot is small, you can cut off the rotten part of the cactus with a knife, then apply plant ash to the wound and leave it in a cool, dry place to dry. Also, if the cactus is rotten, you can cut off the rotten place, sprinkle some quicklime to burn the wound, sprinkle it several times, and then dry it.

If it is summer, you can sprinkle hot sand directly on the cactus wound at noon on a hot day, and after drying, you can resume normal management. "The Book of Flowers" is the signed author of Toutiao.

Socket decay. If the decaying part of the cactus is in the form of a nest, the carrion should be removed in time, and the inactive part should be directly covered with a low-toxicity fungicide with a concentration of about 70%. You can also use a reagent such as Dikepine, which can remove rotten roots, mix them into the soil about 1cm high in the pot, and finally sprinkle with fine soil or sand.

Its surface is completely dry and it should be placed in a cool place before it can be restored to normal management. At this point, emphasize that the dose is only two or three grams. Don't put the medicine that removes carrion on yourself, it's poisonous.

Wash European clothes as soon as they come across them. If it accidentally gets into your eyes, mouth or nose, go to the hospital immediately.

Rot in multiple places. If there are many blue spots or even cavities on the cactus sphere, if there is no fruit disease in the middle, after removing the rotten flesh, the rotten spots should be repeatedly cleaned with 1% copper sulfate and other chemicals for disinfection and sterilization. Put the potted plant in a cool, ventilated and dry place, and when it is sleepy and dry out, it can be replanted.

Strengthen management. After replanting cactus, it is necessary to strengthen management and reasonable watering to avoid root rot caused by excessive humidity in the pot; Reasonable fertilization, low fertilizer concentration, it is best to dilute with water before application. Before the end of the cactus growth period, it is generally once every half a month, gradually decreases in autumn, and stops fertilizing in winter.

Summary of the rules. Clean and decaying tissue needs to be removed first. The area that needs to be removed can be treated with quicklime and removed directly after covering. Repeat 2-3 times, then place in a cool, ventilated and dry place to dry before replanting.

Many friends will raise some flowers and plants, but they don't know much about some of their maintenance knowledge, such as can the cactus be saved if it is shriveled? If the cactus is shriveled and saved, if the bottom is withered but not rotten, and it feels hard to the touch, it is a normal natural aging phenomenon, and the withered part needs to be cut off, and the incision is dried and replanted. If it is blackened, the bottom is shrunk and pinched softly, and the thorns above are also soft, that is the rotten roots caused by excessive watering, the cactus is a drought-tolerant plant, and the most afraid of more water is there, at this time, it is necessary to cut off the top and dry it for one to two days before cuttings, it will take root in about a month, and it should be noted that the soil can not be too wet when cuttings.
