What to do if the leaves of dahlia wilt

1. Reasonable lighting

Reason: If dahlias are placed in a high temperature environment in summer, they should avoid direct sunlight. If they are placed in the sun at this time, their leaves will wilt.

Solution: In such a situation, you need to place the dahlia in a cool and ventilated environment where it can see sunlight in the morning and evening, and it will recover normally.

2. Watering in moderation

Reason: In hot seasons, if you water too much or there is continuous or high-intensity rainfall, the roots may rot due to water accumulation and the leaves will wilt.

Solution: If it is caused by over-watering, you can loosen the soil appropriately and place it in a ventilated place to speed up water evaporation. Water less frequently at normal times.

3. Scientific fertilization

Reason: Dahlia is a fertilizer-loving plant and needs to be top-dressed regularly during its growth. However, if the concentration of the topdressing is too high or the raw fertilizer is not well decomposed, it will cause root damage and the leaves will wilt.

Solution: We need to make a judgment first and adjust according to the main cause. If raw fertilizer is applied or the fertilizer concentration is too high, water and dilute fertilizer should be applied in time to restore normal growth.

4. Prevention and control of pests and diseases

Reason: Dahlias are prone to many diseases and pests, including underground pests that are not easy to see on the flowers themselves. For example, underground pests such as female cutworms will eat the roots and cause the leaves to wilt.

Solution: For diseases and insect pests, you should catch the insects and use pesticides in time to control the occurrence of diseases and insect pests, which will gradually restore its growth.
