1、 Change the water in time

Reason: potted lotus needs clean water quality during its growth. If the water is not changed for a long time, the water quality will be very turbid. It is difficult for the roots to grow in such water quality, which will lead to root rot in the long run

Solution: potted lotus needs to change water regularly. It can change water once a week in spring and autumn. It doesn't need to change water too frequently in winter. It can change water once every 10-15 days

2、 Pest control

Reason: because the substrate is not disinfected before planting, or the maintenance method is incorrect, bacteria are bred, which may infect the lotus with diseases and pests, which will also lead to rotten roots

Solution: after preparing the substrate, it needs to be disinfected and then used. If diseases and pests are found, it needs to be treated in time, remove the diseased part, and spray according to the symptoms

3、 Controlled fertilization

Reason: too much fertilization will damage the roots. The long-term use of fertilizer with too high concentration will also lead to Lotus rotten roots

Solution: for plant growth, it is necessary to apply fertilizer reasonably according to the principle of thin fertilizer and more application. Once too much fertilizer is applied, it is necessary to stop fertilization

4、 Replace substrate

Reason: improper substrate provided, soil hardening and heavy viscosity will also lead to lotus root rot

Solution: replace the appropriate soil and provide a new substrate with air permeability and nutrition
