When mowing your lawn, raise the cutting height of your lawn mower to 3 inches. Having longer grass blades will help retain more water.
Odds and ends this month...
Keep the weeds pulled, before they have a chance to flower and go to seed again. Otherwise, you will be fighting weeds for the next several years. Change the water in your bird bath regularly. Standing water may become a breeding ground for mosquitos. Lastly, be on the alert for slugs and snails. Seek and destroy before they do.
