Thick Lawns Prevent Weeds

Thick, healthy lawns have fewer weeds. Why is this? The density and health of the grass will out-compete weeds for water and vital nutrients.

To test this idea, find a thick healthy lawn and walk along the driveway and sidewalk. These areas, where the turf is ending and not as thick, may have a weed or two. Now, walk in the lawn - no weeds. Likewise, look at thinner, unfertilized lawns. You will find weeds all over. Compare this to the thick lawn.

Of course, it is possible the thick lawn owner has used something to kill the weeds. However, we all know how fast weeds pop up, so the likelihood that the thick lawn is only weed-free because of weed control is slim.
