What if the sunflower leaves wither?

First, the planting is too dense

If it is because the distance between each flower is too close, their nutrition will be out of supply and will wither.

Solution: the best way is to plant one in a flowerpot. Sometimes it is more energetic in the morning and a little withered in the evening, which is quite normal. Wait until noon, do not water it, or it will hurt it.

2. Leaf blight

If you get sick, its leaves will grow round or nearly round spots, about 2-4 inches in diameter, the middle will be grayish white, the edges will be brown. Before long, it can expand to 5-20 years old, and fusiform brown spots will appear on the stems and petioles. Generally speaking, it is easy to get this disease in the northeast region, and its germs will remain in the soil and spread when the temperature is high.

Method: to strengthen the care in the field, when cultivating seedlings, we should choose strong ones, which can strengthen its ability to resist diseases. In the early stages of the disease, carbendazim can be sprayed to treat it. At ordinary times, we should pay attention to the hygiene in the fields, clean up the diseased plants, and loosen the soil.

Third, lack of nutrients

If during its adaptation period, the nutrients provided to the leaves are reduced, the leaves will wither without enough nutrients, and it must be taken good care of during this period of time.

Method: to put it in a place where there is light, clean gas and plenty of water. If you plant a lot of trees, you should water and fertilize them according to the time, usually once every 5 days.

4. Seedling cataplexy

If you have this disease, it is mainly because the soil is not disinfected, and then after planting, there is more water in the soil, and the surrounding temperature is more suitable for the growth of bacteria, so it is eroded.

Solution: in this situation, it is generally difficult to save. Carbendazim can only protect those who do not get sick, and there is no way for those who have fallen down, so you must always pay attention to it so that it can grow well.
