Reason: The leaves of pumpkin are white, which may be caused by the lack of potassium fertilizer. It needs a certain amount of fertilizer to grow, blossom and bear fruit. If fertilizer is not applied in time, it will lead to growth problems, and nutrients cannot be supplied for growth, which will lead to the whitening of leaves. Solution: Fertilize in time during the growth period to ensure nutrient supply. If the potash fertilizer applied at ordinary times is too little, it can be replenished. Put it in a well-lit place and get more exposure to the sun. After nutritional supplement, the leaves will slowly recover.

Second, infected diseases

Reason: The leaves of pumpkin are white. If you don't pay attention to it during maintenance, you may be infected with diseases, such as silver leaf disease and powdery mildew. Silver leaf disease is often found, which will lead to leaf whitening after infection. Solution: Treat the infected disease in time, remove the diseased leaves in time, focus on eliminating the diseased leaves, and then spray medicine according to the symptoms.

Third, improper medication

Reason: When spraying drugs, if the drugs are not used properly, the leaves will also have adverse reactions, leading to whitening of the leaves. Solution: Pay attention to the rational use of drugs during maintenance to avoid damaging the leaves. If the medicine is used improperly, we should wipe it off with a wet cloth.
