Diseases and prevention methods of the Chinese lucky charm

Heart rot and root rot of the genus

Both conditions are caused by fungi.

symptom

In plants suffering from heart rot, the tissue at the base of the leaf tube becomes soft and rotten, and has a foul odor. Over time, the leaf tube will fall down on its own.

In plants infected with root rot, the root tips turn black and brown or rot, and no lateral roots grow, thus affecting the plant's absorption of water and fertilizer, causing the plant to grow slowly and become weak.

Prevention and treatment methods

To prevent and control heart rot or root rot, in addition to paying attention to the substrate, watering, and water quality, you can spray 400 times diluted manganese zinc or 400 times diluted aluminum fosetyl to irrigate the leaf tubes once a month for three consecutive times in the high temperature season to effectively prevent the occurrence of the disease. Once heart rot and root rot occur, it is basically impossible to save the plant.

Prevention and treatment methods

Watering the plant is very important, and choosing the right water quality is even more important. Try to choose water with less salt for home watering and use it after exposure to the sun. Control the temperature and avoid temperature angles to prevent frost damage.
