Sunflowers are common summer plants, and you can often see them growing slowly in the sun. However, the maintenance of sunflowers is not easy, and watering is a key link. There are different watering methods in spring, summer, autumn and winter. Let's take a detailed look at them.
1. Spring-Moderate watering The spring temperature gradually increases, and sunflowers also begin to be active. At this time, watering should be moderate to maintain soil moisture. It should not be too wet or dry, and the amount of watering should be determined according to the specific situation.
2. Summer-Keep the temperature high in humid summer, and sunflowers need more water to nourish their growth. Pour water once a day in the morning and evening to keep the soil moist but do not let the water soak in the soil for too long to avoid causing root lesions.
3. Autumn-Reduce watering In autumn, the temperature will start to drop, and the growth rate of sunflowers will also slow down. At this time, the number of watering should be reduced to keep the soil surface dry.
4. Winter-Keep dry and low winter temperatures, and sunflower growth is in a dormant state. Water should be watered less at this time to keep the soil surface dry to avoid damage caused by the influence of cold on sunflower roots.
5. Water in time during drought in summer, the summer weather is hot and the temperature is high, and drought is easy to occur. If the sunflower is not watered in time at this time, the sunflower will lose its vitality or even die. Therefore, water in time during the summer drought.
6. Don't water too much water in summer. Although sunflowers need more water in summer, you can't water too much, otherwise it will easily cause water accumulation and disease. Every time watering should be done so that the ground is moist.
7. Don't water at night in spring and autumn. The temperature in spring and autumn is low and the night is very cool. Sunflowers do not need too much water at this time, so it is not advisable to water at night to avoid causing disease.
8. Watering in winter depends on the weather. Although the number of watering in winter is small, the watering time also needs to be paid attention to. If the weather is particularly cold, water should be avoided to avoid causing root disease.
9. Keep the soil soft. Sunflower roots are long and deep into the soil, so it is very important to keep the soil soft. If the soil is too hard, it will affect the development of sunflower roots.
10. Timely weeding The growth of sunflower requires a lot of nutrients and water. If there are weeds around it, it will affect the growth of sunflower. Weeding needs to be carried out in a timely manner.
11. Like sunshine Sunflowers are plants that like sunshine, so they need to choose a growing environment with sufficient sunshine. If there is not enough sunlight, sunflowers will not grow well.
12. It is necessary to prevent pests and diseases that sunflower is vulnerable to pests and diseases, such as powdery mildew, aphids, etc. Timely measures need to be taken to prevent and control.
13. Fertilizing Sunflowers in a timely manner require a large amount of nutrients to nourish their growth, so fertilization should be carried out at an appropriate time. Choose organic fertilizer or chemical fertilizer to ensure the healthy growth of sunflower.
14. Don't water too frequently. Although sunflowers require water, they should not water too frequently to avoid causing the soil to be too moist and causing disease.
15. To sum up, the watering of sunflowers needs to be determined according to the season and specific conditions, and should not be too humid or dry. During the growth process, attention should also be paid to maintenance in aspects such as weeding, fertilization, and insect prevention. Only scientific maintenance can sunflowers grow healthily.
