Controlling weeds in your lawn is much easier than you might think. If you’ve put steps 1 through 3 into practice, then you’re well on your way to a weed-free lawn. Feeding your lawn regularly, mowing at the correct height, and proper irrigation all work together to establish and maintain a thick, green and healthy lawn. Weeds have a much more difficult time getting established in a thick healthy lawn. An occasional weed will eventually pop up here and there in your lawn despite your best turf management efforts. However, spot spraying weeds with a turf safe herbicide is much easier than trying to rescue a lawn that’s completely overwhelmed by them.
