Organic Style Love Your Lawn (via WorldChanging): "The secret to having a great lawn without chemicals is Dutch clover. For the past 50 years, clover has been considered a noxious lawn weed, but before that it was an important component in fine lawns—and for good reason. Clover is drought-tolerant, virtually immune to diseases, and distasteful to common turf insects. And it generates its own food by fixing nitrogen in the soil.
So how did this lawn superstar get such a bad rap? Blame the broadleaf herbicides introduced after World War II. Used to kill weeds such as dandelions and plantains, the chemicals also destroyed the clover that was used in many lawn mixes of the time (leaving ugly bare patches in their wake). Today, virtually all seed companies omit clover from their mixes."
