How to tuna can your lawn

Posted by John Bain | July 27, 2010

What ?!

Did you know that many homeowners over water their lawn? The result is a soft, plushy lawn (may be considered a good thing) that grows slower and dies faster as opposed to a lawn that gets a healthy amount of water. This type of lawn also is more prone to weeds, crab grass, and insect infestation.

Why a tuna can ?

Because a tuna can is a super easy way to measure an inch of rainfall or water sprinkling. All you have to do is put a can of tuna on your lawn and water once a week. Don’t stop watering until the can is full. You can use multiple cans to make sure your lawn has even water coverage. Your lawn benefits most when it about 1 inch of water all in one sitting as opposed to small watering’s a few times per week. For maximum benefit water your lawn early in the morning or in the evening to reduce the amount that evaporates from the sun.

So what’s so OpenData about tuna lawns ?

I have created a web application for those who are water conscious to see if they actually need to water their lawns. In the form above ("Your address") all you have to do is enter in your mailing/house address and through the AWESOME POWER OF THE INTERNET the precipitation amounts for the last 7 days will be downloaded from the Environment Canada data archives which will then summed and averaged for an easy to use gauge on how much water your lawn has received and how much water it needs.
