How many days does succulent plant insolate cause black rot? Teach you to control water and ventilation to make succulent plants healthy.

Some flower friends asked, Why succulent plants after a few days on the black rotten water, Because this spring, Has two consecutive days of the highest temperature 30℃, Last year's same period is 20℃, Upper 30℃ is after May things, Slow seedling stage direct exposure, Light is too strong, Very easy to invade infection, Considering that some people may not repair roots before planting, The problem is also probability event.

Flesh is a light-loving plant is right, but slow seedling stage, as long as it does not grow, as long as it does not fade, it is really the less light the better, once the temperature is 30℃, the ventilation is bright and there is no direct light is the foundation of the fleshy slow seedling. In addition to just bought back meat under the seed to slow seedlings, originally planted indoors, this time moved out, but also pay attention to slow seedlings, can not all of a sudden full sunshine, the current plant is more delicate, full sunshine, light sunburn, seed tan, water, different color.

About the black rot control method: transplant, please use carbendazim dip root bar, service pot period meat resistance is very weak, at this time if there is Fusarium oxysporum in the soil, it is easy to get sick, with carbendazim can be treated. Early detection of meat is not right, with carbendazim root irrigation is also very effective, the sooner the better. When it was found that the meat part was black and rotten, the sooner it was removed, the better. If it was necrotic, it would not be good. Don't imagine that it could be restored. Not only would it not be good, but the necrotic part would also become a culture medium for fungi and reproduce a large number of fungi.

Pay attention to the ventilation and heat dissipation of the basin soil. It is a cliché. The sultry basin soil not only creates breeding conditions for Fusarium oxysporum, but also reduces the resistance of the roots. Especially after watering, the root temperature in the soil will be very high. Basin soil is too wet, light is too strong, temperature is too high, it will easily cause some Sedum leaves to fall off the flesh of water, especially garden soil, sand and other water retention is too strong and airtight, should pay attention to water control ventilation.
