Black rot of succulent plants? Teach you to behead and rescue like this.
I believe meat friends all know that the roots of normal succulent plants are not black, but should be light brown or lignified, similar to ordinary plants, so how to identify whether their plants are black rot? it is recommended to dig up the plant first, pinch the black part with your hand, generally the root system or stem part of the black rot is relatively soft, you can feel it, if you are worried about not being safe. You can use a knife to scrape off the skin of the black rot part. If it is black inside, it is almost black rot.
The black rot of succulent plants is a common problem of succulent plants in summer, which is caused by bacterial infection caused by high temperature and too humid soil. "Fusarium" generally exists in the soil. Once there is a wound or a problem in the root system, the bacteria will erode the root system, and soon the root system will appear black rot, and the reason why the black rot spreads more quickly has something to do with watering. After succulent watering, the root system absorbs water and carries the bacteria upward, so the black rot usually starts from the root system and ends at the top. If the root system is only black rot now, it can still be rescued.
The rescue method is commonly known as "beheading".
1. After judging that the succulent plant is indeed black rot, dig out the succulent plant and propose all the black rotten parts. The head is usually beheaded with scissors or razor blades. Disinfect the succulent plant before using it, and do not get infected again. The decapitated part should not be a little black, or it can continue to be infected.
2, cut off the part, the wound smeared carbendazim for disinfection, and then put in a ventilated and cool place to dry the root. The drying time generally depends on the healing of the wound, and the wound can not be planted until it is dry.
3. When planting, the previous flowerpot can no longer be used, and it should be put on the pot with new flower soil and micro-tide soil, and put it in a place of astigmatism and ventilation to root, do not water it before it takes root, because there is no root, watering can not be absorbed, but it may rot.
4, in addition, summer succulent plants relatively slow root, to wait patiently, do not often use your hands to fiddle, generally half a month or so should grow new roots.
5. in popularizing a little knowledge of anti-black rot in summer:
1. First, reduce the number of watering. Although watering is not the source of black rot, moist soil can provide good conditions for bacteria to survive and breed.
2. Ventilation frequently, whether with or without roots, summer ventilation is the most important factor for succulent plants to survive. The same goes for new pots and decapitated rootless ones. Make sure it's well ventilated.
3. Avoid sun exposure. The succulent plants should be properly shaded when the ultraviolet rays are strong in summer.
