Just because you have a sprinkler system doesn’t mean it is being utilized properly. Oftentimes, the controller is set incorrectly by the previous homeowner, the lawn guy, the genius father-in-law, or even worse, the know-it-all neighbor. Depending on the season, it needs to be reprogrammed on a regular basis.

We suggest watering 1-2 times per week in the spring and fall for 25 minutes per station on the smaller pop-up spray heads, and 45-50 minutes per station on the larger rotor heads. This will give your lawn approximately one-half inch of water every time you run it. In the summer, it may be necessary to water 3-5 days per week depending on the weather conditions. Avoid the method of watering every day for 10-15 minutes per station. Short, frequent watering will promote a shallow root system and damage your lawn’s ability to withstand heat, drought, insects, and fungus.

Another common problem we see on our service route is dry patches along the edges of the turf. We suggest watering beyond the edge of the grass and onto the concrete at least 12-24” to cool the concrete and allow for the wind. Many people get too concerned about “wasting” water and watching it run down the sidewalk or drive. However, in order to get the edges properly watered, this is a necessary evil. After all, the concrete gets wet when it rains, right? As your landscape matures and your lawn area changes, the sprinkler heads need to be adjusted or moved to prevent blockage from plants and trees. I can’t tell you how many dry spots we see that are caused by a shrub or tree that has grown over the top of a sprinkler head. Oftentimes, the system is running in the middle of the night, and the owner is unaware of the problem.

Finally, check your system visually a few times a year or have a licensed contractor check it for you. Most irrigation companies in the metro have good techs that can spot and repair potential problems. You can expect to pay $60-90 for an hour’s work, but the pro can do in an hour what the amateur lawn guy can do in three hours. Don’t waste your money on the lawn guy who says he can fix it. Most likely, he doesn’t have the parts inventory with him, or the know-how to resolve the problem. We don’t mow lawns, trim shrubs, and spray trees. We fix sprinklers! Have a professional do the job correctly the first time and enjoy your beautiful lawn.
