    Mowing a lawn can actually be a type of weed control - if done properly. High mowing can actually help reduce weed populations - it has been shown that it even works to slow down the growth of many annual weeds. The taller grass helps shade and cool the soil which restricts the germination of annual weeds. And if annual weeds do appear, mowing can help control the spread of the weeds if you mow regularly the seed heads will not develop and cannot become established.
  2. Proper mowing will help reduce the weeds by increasing turfgrass density!

    If seedheads on weeds, the collect the clipping, otherwise return clipping to soil, you are adding organic matter, nutrients, and water, the turfgrass plant ~ 80% water!

    When mowing, don't excede the the recommended hoc for turfgrass, it can decrease density! I hear of alot of people cutting cool season turfgrass at 4 to 4.5" high, and that is too high for any cool season turfgrass. Stay in between the recommended hoc for your turfgrass!

    Never remove more than 1/3 of leaf blade, if properly fertilized ( quality of fert) you should move almost every week, with few exceptions!

    proper frequency of cut will increase turfgrass density!

    With St. Augustine, If you cut too low or scalp it, the grass will die back from the heat and sun. When this occurs it is not as thick and strong making a lawn prone to weeds and bugs.
