Whatever pro lawn treatments you get, there are still many important tasks left for you to do—or to pay someone to do.

How to Mow Properly

  • Don’t mow grass too short. Most local lawns should not be cut below a height of about two inches.
  • Mow often enough that no more than one-third of the blade is cut at a time.
  • Keep your mower’s blades sharp to avoid tearing grass leaves, which makes them brown and vulnerable to pests.
  • Mow when grass is dry.
  • Leave clippings on the lawn so they can decompose and fertilize the soil, but spread out or remove big clumps of clippings so they don’t form areas of matting on top of the lawn.


Survey your lawn every two weeks or so. If you see problems, don’t overreact; during long dry periods, in particular, browned-off areas may just mean that the grass has gone into a dormant stage to save its moisture and energy.
