When is the best time to water the flowers in winter?

It's better to water the flowers and trees at night in winter, just watering is not enough. Water should be watered according to the changes of seasons and weather. In hot summer, watering around noon is the most taboo, because the soil temperature is high at this time, and the temperature difference with the water temperature is large. At this time, watering will suddenly reduce the soil temperature, and the roots of flowers and trees will be stimulated by low temperature, which will immediately hinder the normal absorption of water. So hot weather should be watered before 10 am or after 5 pm. On the contrary, in areas without frozen soil in winter, when flowers and trees cultivated in the open field need to be watered in winter, it should be done around noon. In spring and autumn, it is best to water after 10 a.m. and before 4 p.m.
