Today, the editor will talk about this issue specifically for you, and also tell you how to prevent and control diseases and insect pests when growing Kalanchoe in summer.

How to grow chrysanthemum

The plant Kalanchoe is suitable for a sunny and warm environment. It grows fastest when the outside temperature is between 20 and 25 degrees.

After these diseases occur, not only will the growth of Kalanchoe be affected, but its leaves will also be severely damaged, affecting its ornamental value. The best way to deal with it is to spray the medicine directly, and it must be used continuously for 2 to 3 times to effectively eliminate the pests.

2. Rhizopus and stem rot

Rhizopus and stem rot are also diseases that are prevalent in Changshu in summer. There are many reasons for their occurrence, mostly because the growing environment is humid, hot and has poor air permeability. The best way is to reduce the humidity of the air and enhance indoor ventilation. At the same time, you can also spray 5% of carbendazim on the sick chrysanthemum. After two to three consecutive uses, the disease can be significantly controlled.
