    Is it true that "Dew" on the lawns is a better source than water to help the lawns?? I know it's a stupid question but I was curious.

    Not a bad question.As far as I know dew is just water in the form of droplets. As the exposed surface (grass, trees, etc.) cools by radiating its heat to the sky, the rate at which atmospheric moisture evaporates from the surface drops below that at which it condenses on the surface from the air, so that droplets are formed. So essentially its like a very light rain. I've heard people say that "rain" water is better for grass than "well" water but I'm not sure how much scientific evidence there is to back that up. I suppose it could be more beneficial because of its timing (early morning),but also a threat- when formed just after dark(fungus habitat). Any one else have any info? hope this helps.

    Rain by far is better, actually contains trace elements of nitrogen.
