Watering your lawn
It's dry in Charlottesville so watering your lawn would help it stay healthy and avoid burnout. Water at night so the water costs less and the hot summer sun doesn't dry it up. Watering at night lets the water soak into the ground. Also, apply some fertilizer to the grass before you water to give it an extra boost.
Avoid cutting the grass too short. Short grass is susceptible to weeds and unwanted growth. The taller the grass is, the more ability it has to stave off weeds!
