Well, after years of timely rain in the summer it looks as though this will be a hot dry year. If you do not have the ability to irrigate your lawn with approx 3/4 to 1″ of water per week, it is better for your turf to allow it to go dormant. Giving the lawn just enough water occasionally to tease it out of dormancy can and will do serious damage to the turf.
People with irrigation systems should also keep in mind that less frequent deep watering is better for turf as well as plants.
Keep in mind as the weather gets cooler and the rains start the lawns will come out of dormancy for the fall growing season. At that time any pest (grubs, chinch bugs etc) damage will become apparent. You are well served to scout for these pests while the lawn is dormant as they will cause serious damage to the turf.
Enjoy summer and if you need help with your lawns and or gardens we are here for you.
