Be sure to water again when your footprints in the grass look gray and do not quickly spring back. This is the first sign of wilting. Check your sprinklers and your drip system. Clean them out if they are clogged. Brown areas in your lawn are usually the result of poorly adjusted or poorly placed sprinklers.
Weeds Keep weeds under control by proper mowing and watering and by spot spraying if necessary.
Crabgrass is a summer annual weed that should be controlled with a weed preventer applied in February. If crabgrass does emerge, it can be controlled by spot spraying in early summer. Fertilize Summer fertilizers are slow release formulations. You may also apply Ammonium Sulfate at half the usual rate. Use a rotary spreader for quick and even coverage.
