1, improper fertilization, fertilization exceeded the needs of plants. At first, the leaves were uneven in brightness, and then the roots rotted and the leaves turned yellow. The treatment method is to stop fertilization and water more, or turn over the basin to clean the roots and replace them with new soil;
2, nutrient loss, all kinds of nutrients contained in the basin soil have been exhausted, nitrogen, phosphorus and potassium have not been replenished in time, plants lack nutrients, and leaves are yellow and thin. The treatment method is to replace fertile loam and alum fertilizer water in time;
3, the sun is insufficient, although chlorophyll is a semi-negative flower, it needs at least four hours of astigmatism every day, otherwise chlorophyll will decrease and leaves will turn yellow. The treatment method is to take spare time every day to put the spider plant in the sun for a few hours, but not too much sun;
4. The pot soil has poor air permeability and water permeability, and the pot soil is not dry for a long time, and the root system has difficulty breathing, which leads to yellowing of leaves. The treatment method is to loosen the soil in time and control the moisture.
