Should I water my lawn?

That's a common question we all ask. For some information view the previous post on Low and No Cost Lawn Care where I discuss proper mowing and watering techniques.

I found a site that can help you answer the question of when to water your lawn in the Northeast. I've embedded it below for easy access. It should be pretty self explanatory. (Sometimes this tool is broken)

It looks like it finds the weather station closest to the zip code you entered to get relevant weather data for your area. Then based on the amount of precipitation (rain) and evapotranspiration in your area, recommends the amount of water your lawn needs.

It doesn't seem to account for soil type, but it still seems to be a good general guide.
