What to do if the leaves of dahlia wilt

1. Reduce light

1. Reason: When the temperature is too high in summer, the leaves are prone to lack of water. At this time, the stomata of the leaves are closed and the leaves will wither.

2. Solution: This kind of withering is not real withering, but physiological. Just add some water to it and it will be fine at night. And don't let it be exposed to the sun directly.

2. Watering correctly

1. Reason: It has high requirements for water. If it is not given water in time, the leaves will easily wither.

2. Solution: Increasing the amount of water appropriately, especially when its leaves are wilting, will be more conducive to its growth.

3. Correct fertilization

1. Reason: It blooms for a long time, so it needs a lot of fertilizer. If concentrated fertilizer is applied or the amount of fertilizer is insufficient at this time, its leaves will wither.

2. Solution: When you see that the color of its flowers becomes lighter and the texture of its leaves is very thin, you need to add dilute fertilizer in time, but not too much.

4. Improve the environment

1. Reason: If the plant is not tied and fixed during its growth, it will easily fall over in strong winds or heavy rains. Even if it is propped up, the leaves will still wilt. In addition, when the temperature is too low or there is frost, its leaves will wither.

2. Solution: Move it indoors before the temperature drops and frost falls, and move it out when the temperature is above 10 degrees.

5. Do not move the flower pot easily

1. Reason: When growing it, some people like to move the flowerpot, which can easily tear its roots and cause the leaves to wither.

2. Solution: Do not move the flower pot frequently. In addition, place bricks under the pot to prevent the roots from growing underground.

6. Prevention and control of pests and diseases

1. Reason: If it is damaged by diseases and insects, its leaves will wither.

2. Solution: Spray the medicine in time and clean up the pests and diseases.
