What is the reason for the root rot of lotus

Causes of root rot

Fertilizer damage

The lotus does not require much fertilizer, and a thin layer of fertilizer in ordinary soil can make it grow very strong. Too much fertilizer can easily burn the roots. Some flower lovers may directly use the mud from the fish pond to plant bowl lotus, which is a wrong method. There are too many nutrients in the fish pond and the lotus can’t bear it.

Pests and diseases

Before planting, the potting soil was not disinfected (such as exposure to the sun, mixed with carbendazim, etc.). There may be a large number of parasites in the potting soil. After planting, they will multiply in large numbers in a relatively humid and warm environment and corrode the roots and rhizomes.

Pinch the leaves

In home care, flower lovers will pinch the leaves to prevent the plants from growing too fast, but ignore the leaf cross-sections. The leaf stem is hollow and shaped like a water tube. If it is pinched off and immersed in water, the water will flow along the tube wall to the roots, causing rot.

Water temperature is too high

The growth temperature of bowl lotus is relatively high, around 30℃, it grows rapidly and can extend the flowering period. However, when the water temperature exceeds 40℃, the growth of the bowl lotus gradually slows down until it dies.

Treatment

Proper fertilization

When fertilizing water lilies, you should stick to applying small amounts of fertilizer. If the planting soil is relatively fertile, you can mix it with garden soil to reduce its fertility. In daily maintenance, just apply thin liquid fertilizer.

Control water temperature

Try to keep the water temperature between 25 and 30 degrees Celsius. If you cannot judge the water temperature, you can use a thermometer to assist.

Pest and disease control

Early detection and early treatment. Use diluted pesticides to kill insects in time.

Protect the blades

When trimming the blades, fix the corrected section on the water surface and do not let it float down. Reduce root damage caused by excess water in the petiole.
