Light sprinkling is only beneficial for newly planted turf when
the roots are developing in the very top portion of the soil. As
turf is established, roots extend deeper into the soil. Light sprinkling
will encourage root development only near the soil surface and
stunt deeper root growth. Shallow root systems require frequent
watering to keep the surface wet, creating an ideal environment
for weeds and diseases. Although some grasses have less extensive
root systems than others, deep, infrequent watering that allows
water to penetrate the top 6 to 8 inches of soil will promote healthy
root growth. It also maximizes water-use efficiency and turfgrass
Lawns need uniform coverage to maintain their vigor and a healthy
appearance. Brown spots in a lawn are often due to uneven coverage.
Use a sprinkler system that can provide
Too much water is not only wasteful but can also increase turf growth,
which requires more frequent mowing. Saturated soil can cause poor
soil aeration and, as a result, weaken turf making it vulnerable
to diseases and invasions of weeds. Not enough water can cause turf
to dry out.
Let the soil partially dry out between waterings. Water when the
top two inches of soil have dried out. Use an object such as a screwdriver
to probe your soil and measure the depth of the moisture.
Avoid runoff and puddling by spacing out, or
cycling, irrigations throughout the week until the desired
amount is applied. On compacted or heavy
clay soils, aerify the soil so that
water can easily move into it.
