Just my $0.02. I think collectively as Americans the dumbest thing we do is mow our lawns. We gripe about $3.00 per gallon gas (and the price will get higher), extoll the virtues of organic and pesticide free food, and are warned every day in the summer about the ozone level. Then what do we do? We go home and spread pesticides and herbicides on our lawns around our gardens (your gardens not mine) and run gas guzzling mowers (calculate the mpg on your grass shortener sometime) without any catalytic converters. As for watering, just how much of that precious natural resource do you think is out there? The answer is less than you think regardless of where you live.
We must be nuts!
If you want to de-thatch your lawn try this. In the spring right after the snow is off mix the following ingredients.
12 ounces beer (anything but light beer, un-pasteurized draft is best)
12 ounces cola (not diet, you need the sugar from real cola)
8 ounces non-sudsing household ammonia
Put in a hose sprayer and spray across the lawn. Wait one week and manually rake, If you are lucky there will be very little to rake as the thatch will self-compost in place thanks to this recipe. If you don't rake that is ok too because the first time you mow it should disappear in the mowing.
Thanks for letting me vent.
