If there have been instances of showers during the week, you won’t need to water your lawn as often. If you use an advanced irrigation system, you may want to adjust your timers depending on the changing weather patterns. Also, be sure to inspect your system for blockages and leaks for effective results. The best time to water your lawn is early in the morning before the sun rises too high. If you water in the afternoon, it will evaporate before your lawn can adequately absorb it.
