1、 Watering too much
Reason: Houttuynia cordata likes to grow in a humid environment, but does not like wet water. Once watered too much, the roots are not absorbed, which will lead to root rot and affect the later growth p>
Solution: water regularly at ordinary times. Do not make the basin soil too dry, but control the amount of water. It is OK to pour it thoroughly at ordinary times. Once too much water is watered, it is necessary to promote the discharge of excess water p>
2、 Too strong fertilization
Reason: the growth of Houttuynia cordata needs reasonable fertilization, but the fertilization must not be too much, which will exceed the bearing range of the root, and the selected fertilizer should not be too thick, which will lead to fertilizer damage and rot of the root p>
Solution: pay attention to reasonable fertilization at ordinary times, adhere to the principle of thin fertilizer and frequent application, and apply low concentration fertilizer every time to ensure the growth needs. If there is too much fertilization, it needs to be watered and diluted p>
3、 Infectious diseases and insect pests
Cause: diseases and pests may be infected during maintenance, such as root rot, which will also cause root rot and affect the growth of the whole plant p>
Solution: disinfect the soil before putting it into the basin, kill the hidden bacteria and insect eggs, treat in time after the disease, and spray the corresponding medicine p>
4、 Wrong soil
Reason: if the soil used is viscous alkaline soil, it can also lead to root rot p>
Solution: new soil needs to be replaced, which should be loose, breathable and soft p>
