Don’t water the lawn!
I saw my neighbour watering her lawn yesterday evening and can’t help but think this is a waste of time, money (we’re on water meters) … and of course water.
During dry weather there is no need to water established lawns unless absolutely necessary. Established lawns will turn brown in hot weather but it’s not worth wasting water on them, as the grass will soon recover. http://www.oxfordprospect.co.uk/Extreme-Gardening.html
