when there is the sun can you water the lawn?
watering in the lawn should be provided early in the morning, or in the evening hours; this is because, especially in summer, if you water the turf in the middle of the day, with a scorching sun that warms it, and a torrid climate, in essence the water immediately evaporates because of the heat present in the garden. Therefore, on the one hand your watering will hardly have fulfilled all its function effectively, since most of the water will evaporate, without wetting the soil; on the other side the water that evaporates raises the humidity around the plants, but also raises the temperature, and if this is very high, it practically "boiled" the young leaves of the turf seedlings. Sometimes it happens to see, especially in the areas of urban furniture, irrigation systems that are in action precisely during the hottest hours of the day; but often this hourly choice is due to the fact that in a large city it is impossible to water all the flowerbeds simultaneously, or the water demand would skyrocket. In addition to this, on some occasions, with very little rain, it happens to have to water a turf several times in a day, and therefore also in the middle of the day. Being able, in the garden of the house, it would be opportune to water in the first hours of the morning, in summer, or when the climate is still fresh; so as to leave the plants many hours to absorb water, and so as to be able to wet the soil thoroughly with smaller amounts of water. If you can't really water in the morning, do it at night, even if, in summer, the lawn stays warm for many hours, even after the sun has set, and you would therefore go to wet a warm soil, with cold water, what that plants don't like much. In the periods of the year not characterized by a very hot climate, you can water at any time of day, but it would always be better to water in the early hours of the morning.
