Watering Your Lawn

Why more isn't better

Watering your lawn is essential to keep it thick, green and growing, so it’s no surprise that many homeowners tend to overdo it. But it’s important to realize that too much water can actually harm your lawn – creating overly wet conditions where fungal diseases can thrive.[1]  Bigger picture: Excessive watering can increase the amount of fertilizer and pesticide runoff, impacting your local water quality.[2]

During typical weather, most lawns need just one inch of water per week to stay in good shape.[3] Using a rain gauge is an easy way to keep track of how much water your lawn is getting from Mother Nature and from your sprinkler. Your grass will also show clues when it’s time to water. Keep an eye out for a bluish-gray tint, curling blades and footprints that don’t “bounce back” as quickly.[4]

Here are more Yard Smarts tips for smarter watering:

• Water early in the morning (between 4 a.m. and 9 a.m.), when temperatures are lower and there’s not as much wind. This will prevent evaporation and allow water to penetrate the grass better.
• Instead of several shallow sprinklings, give your lawn a few deep drinks per week. This encourages a health root system, making it more difficult for weeds to take over.
• To help your lawn retain moisture, mow your grass high – only cutting the top third of the blade.
• Be sure your sprinklers are angled correctly to cover your green areas only, so you won’t be wasting water on the pavement.
