The frequency of weekly
watering depends on your grass species, total water requirements
for the week, and how long your soil will absorb water before running
off into the gutter.
Warm-season
grasses
Warm-season grasses have extensive root systems that penetrate deep
into the soil and require deep and infrequent watering. Water as
few times a week as necessary to fulfill your weekly water requirements
without causing excessive runoff. Usually 1 or 2 times a week is
sufficient.
If you want to determine the maximum amount of time your sprinklers
can be left on at one time, observe a cycle from the beginning to
the time when runoff begins. That is the maximum amount of time that
you let your sprinklers run in any given watering. Space out the
applications evenly during the week.
Cool-season
grasses
Cool-season grasses require more frequent watering than warm-season
grasses because their root systems are not as extensive. Divide the
required weekly minutes into about 3 equal irrigations, evenly spaced
throughout the week. Fewer applications may be sufficient during
cooler months. Desert areas, slopes or areas with shallow soils also
need shorter, more frequent irrigations than warm-season grasses.
