when it is sunny can you water the lawn?
watering the lawn should be provided early in the morning or in the evening; 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 evaporates immediately due to the heat present in the garden. So, on the one hand, your watering is unlikely to have performed its full function effectively, since most of the water will evaporate, without wetting the soil; on the other hand the evaporating water raises the humidity around the plants, but also raises the temperature, and if this is very high, it practically "boils" the young leaves of the turf plants. It happens sometimes to see, especially in the flower beds of urban furniture, irrigation systems that are in action right in 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 flower beds at the same time, or the water demand would skyrocket. In addition to this, on some occasions, with very low rainfall, it is necessary to water a turf several times in a day, and therefore also in the middle of the day. Being able, in the home garden, it would be advisable to water in the early hours of the morning, in summer, or when the weather is still cool; so as to leave many hours for the plants to be able to absorb the water, and to be able to thoroughly wet the soil with less water. If you really can't water in the morning, do it at night, even if, in summer, the lawn remains warm for many hours, even after the sun has gone down, and you would then go to wet a hot soil, with cold water, what that plants don't like very much. In periods of the year not characterized by a very hot climate, you can water at any time of the day, but it would always be better to water in the early hours of the morning.
