What's wrong with the yellowing leaves of daffodils? How to deal with the yellowing leaves

1. Unsuitable water and soil

Reason: Daffodils can be grown in water or soil. If the water quality or soil used for cultivation is not suitable, it may cause the leaves to turn yellow.

Treatment method: Choose appropriate water quality or soil when cultivating and maintaining. The water quality can be slightly acidic water, or you can take out tap water and let it stand for a period of time before using it for hydroponics. The soil can be loose, fertile, acidic soil, and the soil should be replaced every one or two years of cultivation.

2. Improper temperature

Reason: Temperature is also a very important point in maintenance. If the temperature is too high for a long time, the leaves will become dry and yellow. If the temperature is low for a long time, the daffodils will be frostbitten and the leaves will turn yellow.

Treatment method: Maintain a good temperature, try to keep the temperature at around 15-20 degrees, provide shade to cool down in summer, and pay attention to keeping warm in winter.

3. Improper lighting

Reason: Daffodils need sufficient diffuse light to grow. Long-term lack of sunlight will lead to the inability to synthesize nutrients, and the leaves will turn yellow in the long run. When the light is too strong, the leaves will be burned and turn yellow.

Treatment method: Give daffodils sufficient diffuse light. When they are exposed to the sun in summer, they need to be moved to a cool place in time.

4. Infection with pests and diseases

Reason: If the leaves are infected with diseases and pests during maintenance, they may also turn yellow.

Treatment method: Strengthen ventilation to prevent the occurrence of diseases and pests. After the occurrence of pests and diseases, spray drugs for treatment according to the symptoms.
