1. First of all, replantation: If the root of the golden chain is rotten, it can be replanted in soil suitable for its growth. You can take it out of the original soil, remove the rotten roots and transplant it into the new soil.

2. Secondly, control the watering amount: too much watering will lead to the root rot of underground gold chain, so it is necessary to pay attention to the control of watering amount. Generally speaking, before the soil surface dries, water it gently to avoid excessive water accumulation.

3. Finally, strengthen conservation: Proper fertilization will help the growth of underground gold chains, but excessive fertilization will also cause root rot. Therefore, it is necessary to control the amount of fertilizer to avoid too much fertilizer soaking the soil in the gold chain.
