What is the problem with Houttuynia cordata root rot? What should I do if Houttuynia cordata root rots?

1. Too much watering

Reason: Houttuynia cordata likes to grow in a humid environment, but does not like water. Once it is watered too much, the roots will not absorb it, which will cause the roots to rot and affect its later growth.

Solution: Water the plant regularly and do not let the soil in the pot become too dry. However, you need to control the amount of water and just water it thoroughly. If you water too much, you need to promote the drainage of excess water.

2. Fertilization is too concentrated

Reason: Houttuynia cordata needs to be fertilized reasonably during its growth, but not too much fertilizer, which will exceed the tolerance of the roots. The fertilizer selected should not be too concentrated, which will cause fertilizer damage and rot of the roots.

Solution: Pay attention to reasonable fertilization at ordinary times, adhere to the principle of applying thin fertilizers frequently, apply low-concentration fertilizers each time to ensure the growth needs. If too much fertilizer is applied, water should be used to dilute it.

3. Infection with pests and diseases

Reason: During the maintenance process, the plant may be infected with pests and diseases, such as root rot, which can also cause root rot and affect the growth of the entire plant.

Solution: Disinfect the soil before potting to kill the hidden bacteria and insect eggs inside. Provide timely treatment after the disease occurs and spray appropriate pesticides.

4. Wrong soil quality

Cause: If the soil used is heavy alkaline soil, it can also cause root rot.

Solution: New soil needs to be replaced, which should be loose, breathable and soft.
