Lawns: moving into summer conditions

Weed control

As it gets warmer and drier, herbicides that control broadleaf (non-grass) weeds can cause more damage to turf. Weeds must be actively growing, so don’t treat if the weed is dormant.Identify the weed and select the most effective weed control product for that weed. Find help both identifying the weed and finding an appropriate control here:

Summer stress prevention

Mowing

  • Raising the height at which you mow your lawn will reduce weeds and reduce watering requirements of the turf.
  • Mow less frequently to a height of at least 3 1/2 inches.

Watering

  • Watering less often enables deeper roots to form. Consider watering an inch every 10-14 days as a regular practice. When your lawn starts to go dormant, you can discontinue watering for up to 60 days without the lawn dying. If you have fine fescues, that type of lawn may need a periodic light watering of 1/2 inch or so every few weeks to keep the crowns alive.

  • If you have an irrigation system in your lawn, you should take some time and make sure it is working correctly.
