Remedy: Prepare a proper amount of compound fertilizer, dilute it with water and pour it into the soil for better absorption. Fertilize twice a month and it will recover soon.

Reason: This is a very fertile flower, and it should be fertilized immediately when it is maintained. If it is not fertilized for a long time in its growing season, its leaves will turn yellow because of lack of nutrition.

Solution: Prepare some compound fertilizer in advance, dilute it with cold water and pour it into the flower soil. After that, the frequency of fertilization was increased to 1-2 times a month to show its nutritional composition.

Overwatering

Solution: First dig out the original flower soil, and use scissors to cut off the roots that have turned black and rotten and the leaves that have turned pale yellow. Then prepare some new soil that is not easy to store water in advance, plant the main stem in it and keep it in the shade.
