Spring Lawn Tips for Mowing and Weed Control

Weed-free lawn

Beautiful, weed-free lawn

It’s spring and the thoughts of landscape DIY-ers turn to the lawn. Here are some answers to questions about the lawn and its care this time of year.


  • The best looking, weed-free lawn starts with proper mowing. Mow as soon as the grass starts to grow to remove any brown tips.
  • Keep the grass mowed to 3 to 4 inches tall. At that height, grass shades out weeds, develops deeper roots, and cools the soil.
  • Cool-season grasses, such as Kentucky bluegrass, fescues, and perennial rye grass grow faster in cool weather. That means you mow more frequently in spring and early summer to keep it in the 3-4 inch tall range, and less frequently in mid- to late summer and into fall.
  • Warm-season lawn grasses are in their rapid grow phase mid-spring through early summer. That is a good time to fertilize warm-season lawn grasses.
  • Leave clippings on the lawn. As they break down, they return trace nutrients to the soil. If the grass was tall when it was mowed, spread out any large, heavy clumps so the clippings don’t smother the lawn.
