Sunflower likes warm and humid environment, so we'd better keep the soil in the basin moist. Our daily watering should follow the principle of "dry and wet", not half dry and half wet, watering must be done to make the root of sunflower get water nourishment. Although sunflower likes humid environment, but we can not over water, resulting in water in the basin, this will lead to sunflower rotten root phenomenon.
Summer is generally hot and dry, so you can water more properly in summer. In summer, not only the weather is hot, but also the water of sunflower evaporates very fast. Summer is also the season of sunflower's vigorous growth, and the water demand increases correspondingly. So in summer, we can water sunflower twice a day. In addition, when the weather is too hot, it should also be scattered. Spray water around the leaves of sunflower plants to keep the humidity in the air. The amount and times of watering should be determined according to the climate and the humidity of the soil in the basin. There is no need to copy the formula
In winter, when the weather is cold, the evaporation rate of water is correspondingly low, and sunflower grows relatively slowly in winter, so it is not necessary to pour too much water on sunflower in winter. Especially when it's cold and rainy, do not water more, or even do a good job of drainage. In winter, you can wipe the leaves of sunflower, not only make sunflower bright and clean, but also increase the humidity, give sunflower proper moisture
