This encourages deeper rooting and makes your lawn healthier for the rest of the summer. It also delays the first time you have to mow the grass. Don't sprinkler grass lightly, deep-soak it. Light watering can't get water down deep into the soil. The grass develops shallower roots and is both less drought-resistant and more prone to winterkill.

Sprinklers that throw larger drops in a flat pattern are much more effective than those with fine, high sprays, which can be blown about and evaporate quickly. If you water when it's windy, you will find the water going everywhere except where you want it to go. Lawn Care Don't water your lawn too much. An automatic system can be preset, but a sprinkler on the end of a hose needs your personal attention. Buy timer attachments that hook on between the faucet and hose, or set a kitchen timer to ring in 15 to 20 minutes to remind you to move the sprinkler to a new area.
