What to do if the leaves of Huangli turn yellow and rot

reason

The water is big

A large amount of water is stored in the thick leaves of Huangli, which can support a period of time without watering. If too much water is given, the roots of Huangli will grow poorly, causing the leaves to wilt and rot.

Black Rot

The leaves will fall off with a slight touch. If this happens, check the roots in time and see if there are any abnormalities in the stems close to the soil. If the stems are found to turn red or black, cut them off in time. Black rot mainly presents the following phenomena:

The inside of the plant rots and the plant falls over.

The stem rots, and black spots appear at the base of the stem, gradually expanding and spreading.

Fungal rot, which causes brown and water-soaked spots to appear on both the stems and leaves of the plant.

Workaround

disinfect

The disinfection mentioned here requires comprehensive disinfection, including all objects that the plants come into contact with, from as small as a grain of sand to as large as flower pots and spades. Wash your hands carefully and wear gloves before operation.

resection

Use a sharp knife to scrape away the infected area, then stuff the wound with crushed charcoal and sulfur and leave it in a cool place to dry. Replant according to the different rotten parts. If the stem is rotten, remove the entire stem and then use branch cuttings.

To avoid fungal diseases, you should spray fungicides after cutting to prevent recurrence.
