The latest causes of black rot in succulent plants in winter

The black rot in succulent winter is caused by a fungus called Fusarium oxysporum, which can not only infect plants, but also survive in the soil and infect many plants. After succulent infection with black rot, yellowing appears on the leaf surface at the beginning, there are gray-white disease spots on the back, and a gray-white mildew layer appears, and then spreads to the leaf surface, which will eventually lead to leaf curl and dry up, and even death, which is a common plant disease.

Usually, black rot likes to appear in hot and humid environments, but the temperature in winter is lower and the environment is drier, so why does black rot occur? The pro-agriculture network is here to introduce the reasons why this disease appears in winter:

1. Watering mode

Some friends have no scruples when watering succulent plants in winter, so there will be stagnant water in the leaf heart. coupled with frequent watering, the water temperature will get higher and higher in the right sunny weather, which will become muggy and humid. black rot is easy to occur in this environment, and at the same time it will cause insect pests.

two。 Too much watering

In winter, succulent plants are almost in a state of stopping growth, and succulent plants are placed indoors in winter. Indoor ventilation is very poor in winter. If you still water succulent plants according to the amount of water used in the past, succulent plants can not absorb moisture. The environment is not ventilated and the time is too long, which can easily lead to black rot.

If it has been black rot, then can only cut off all the black rot, and then apply fungicides in the cut, after a period of time to observe, if it continues to black rot, then only cruel throw away.

So how to prevent black rot in winter? As a matter of fact, winter is not a high incidence period of black rot. Black rot can be avoided as long as it is properly maintained. In winter, you only need to pour a little water on the succulent plant, and it is poured directly on the soil. Do not pour it directly from the top of the succulent plant, and try to make zero contact between the water and the succulent succulent plant. If you pour too much water, you should find a well-ventilated place to put it for a period of time. Short-term water or soil is too damp and succulent can be tolerated.

The above is the introduction of succulent winter black rot brought by the pro-agricultural network. It should be noted that this "Fusarium oxysporum" can survive in the soil, so if the succulent plant is infected and dies, the planted soil should be disposed of, and the flowerpot should be disinfected to prevent fungi in the soil from infecting other plants.
