We typically recommend watering your lawn early in the morning to give it plenty of time to dry out before nightfall. However, if you forget to water your lawn in the morning, watering any time is better than the alternative. Be sure to ask us about automatic sprinkler systems to help make remembering to water your lawn more convenient and hassle-free. If you have an automatic or underground sprinkler system already installed, be sure to check it periodically to ensure adequate coverage of your lawn. Occasionally, sprinkler valves and timers misfunction and need to be repaired or replaced by an expert.
