If dahlia leaves have wilted, and it is caused by excessive light, you need to reduce the light; if it is caused by improper watering, you need to water correctly; if it is caused by improper fertilizing, you need to fertilize correctly; if it is caused by a poor environment, you need to improve the environment; if it is caused by casually changing its position, you need to be careful not to move the pot easily; if it is caused by pests and diseases, you need to control them promptly.

1. Reduce Light

1. Cause: When summer temperatures are too high, the leaves easily lack water; at this time the leaf stomata close, and the leaves will appear withered.

2. Solution: This kind of wilting is not true wilting but is physiological; as long as you appropriately replenish a little water, it will recover by evening, and you must not let it be exposed directly to the sun.

2. Water Correctly

1. Cause: It has high water requirements; if water is not given in time at this point, the leaves will easily wither.

2. Solution: Appropriately increase the amount of water; especially when its leaves are wilting, this will be more beneficial to its growth.

3. Fertilize Correctly

1. Cause: It blooms for a long time, so its fertilizer demand is very high; if concentrated fertilizer is applied at this time or the amount is insufficient, its leaves will wither.

2. Solution: When you see its flower color become lighter and the leaf texture very thin, you need to promptly supplement it with dilute fertilizer, but it must not be excessive.

4. Improve the Environment

1. Cause: During its growth, if it is not tied up and secured, it will easily lodge in strong wind or heavy rain, and even if it is propped back up, the leaves will still wilt. In addition, when temperatures are too low and frost occurs, its leaves will also be damaged and wither.

2. Solution: Before the temperature drops and frost falls, move it indoors, and wait until the temperature is above 10 degrees before moving it back outside.

5. Do Not Move the Pot Easily

1. Cause: When growing it, some people like to move its pot, which easily tears its root system and makes the leaves wilt.

2. Solution: Normally you should not frequently move its pot; in addition, place bricks under the pot to prevent the roots from growing into the ground.

6. Prevent and Control Pests and Diseases

1. Cause: If it is damaged by pests and diseases, the leaves will also wilt.

2. Solution: Spray pesticide promptly and remove the pests and diseases.
