1、 Insufficient water

1. Reason: Goldfish grass is very sensitive to water. Its pot soil must be kept wet. When Potting Seedlings, it must be fully watered. Too little water will cause the leaves to turn yellow

2. Treatment method: water the plants immediately to supplement water, and keep the soil moist at all times, not too dry. However, do not accumulate water and damage the root system, otherwise the leaves will also turn yellow

2、 The temperature is too high

1. Reason: Goldfish grass is more resistant to cold and lack of high temperature. High temperature will have an adverse impact on its growth. If the temperature is higher than 15 degrees, the plant will grow slowly and the leaves will turn yellow

2. Treatment method: it should be transferred to a cool and shaded place for curing and let it recover slowly. In the later stage, the temperature of plant growth should be controlled at about 7-15 degrees, which is conducive to plant growth

3、 Excessive nitrogen fertilizer

1. Reason: Goldfish herb has Rhizobium, which has the function of nitrogen fixation. Therefore, under normal circumstances, nitrogen fertilizer is not applied. If too much nitrogen fertilizer is applied, it will burn the root system and cause the leaves to turn yellow

2. Treatment method: when applying fertilizer, phosphorus fertilizer and potassium fertilizer shall be used as the main fertilizer, and the amount of nitrogen fertilizer shall be reduced at the same time
