Lawn Management
Turfgrass selection
Turfgrass often makes up the largest area in the landscape. While warm-season grasses, like bermudagrass, are drought resilient, it's easy to over water. A few simple lawn management tips will keep your lawn growing with less water.
Plant a turfgrass that is adapted to Oklahoma's weather and rainfall. Make a note of your site conditions before selecting a turfgrass, avoid planting tall fescue in full sun areas and keep in mind it requires twice as much water as bermudagrass. Consider using tough, shade-tolerant perennials and mulch in shaded areas that require less maintenance and water than cool-season grasses.

Be a water wise irrigator
Water deeply and infrequently to encourage strong, deep root growth. Check for the first signs of wilt before watering. Use the cycle and soak approach, turn on irrigation and turn it off at the first sign of runoff and allow water to soak into the soil, turn the system back on and repeat. Use a rain gauge or tuna can as a guide. Bermudagrass lawns need about 1" of water a week during the hottest month and tall fescue lawns need about 2" per week. Take rainfall into account and turn your system off to avoid waste. Visit the irrigation schedule page for more information.
Manage for water efficiency
Mow at a taller height, grass acts like a natural mulch retaining soil moisture and also shading out weeds. mowing too low stresses turfgrass and requires more frequent watering. Use a mulching lawn mower or compost grass clippings to keep valuable nutrients onsite rather than in the landfill.
Aerate the lawn to alleviate compaction and increase water infiltration. Topdressing with no more than 1/2" of compost will provide beneficial nutrients and improve water holding capacity of the soil. Only fertilize when needed, and always take a soil test first.
