In the run up to summer, we Brit’s hope for a long, dry and hot few months after a wet and grey winter and unpredictable spring. However, for our lawns, this is a nightmare! It is during this dry and hot weather that grass can suffer from drought stress. This strain is amplified when the dry period becomes hot or windy. You may start to notice your lawn changing to a paler green, yellow or brownish colour and beginning to look patchy.
