Today, I will share with all the flower friends the treatment methods after seeing a cactus turn black.Observe the rotten partCacti rarely get sick, and if you find that the stem turns black or brown, it is almost certain that this part has rotted. Cacti have strong vitality, and as long as we treat the rotten part a bit, most of them can be cured and survive.(A cactus with black rot at the bottom)If the stem or the top part rots, the discolored part is usually the black part, and we just need to cut it off cleanly. But if the bottom of the cactus turns color and becomes soft, we need to check it more carefully, as there may be root rot along with the stem rot, and we need to cut off the roots together. If the bottom of the stem is discolored but feels very hard when pressed and does not collapse, it is often a sign of lignification, which is normal and does not need to be cut.Pay attention to disinfectionWhen cutting a cactus, pay attention to disinfecting the following two places:Tool disinfectionA sharp knife is needed to cut the cactus.

If the wound remains moist, it can easily become a breeding ground for bacteria, leading to secondary rot. It is recommended that flower friends prepare some plant ash, carbendazim, or plant wound healing agents. After cutting the cactus, sprinkle some medicine on the wound to promote healing and prevent secondary rot.Cutting methodsDepending on the different parts of the cactus that are rotting, there are two cutting methods:Top and upper stem rotIf the part with black rot is at the top or upper part of the plant, it is easy to deal with. We directly cut off the upper part that has rotted using a knife, cutting off all the black parts. Then sprinkle some medicine on the wound and continue to care for it. Remember to avoid rain and keep the wound dry when watering. After a period of care, the wound will slowly heal.Bottom and lower stem rotIf the bottom or lower part of the stem rots, it is more troublesome to deal with. We need to remove the cactus from the pot, completely cut off the lower part that has rotted with a knife until the incision is completely green, with no sign of blackness. Usually, after cutting, the roots will also be cut off.
