"Dealing with Osorio Irrigation was a great experience. Wil was very responsive to my initial inquiry and showed up exactly when he said he would for the estimate. He gave me a printed-out quote with informational materials in a folder before leaving my home that day which was quite impressive! He also made sure that all of my questions were answered. I then had some scheduling issues on my end, but Wil graciously accomodated them and was able to schedule the install on the date I requested. The installation of the system went very well and afterwards Wil walked me through the programming step by step and made sure I understood how to use the system. I had a couple of questions after they left the property and I had paid (the exact price quoted by Wil) and Wil got back to me IMMEDIATELY which I was very impressed by and, really says a lot about his character. Finally, the system works great and my grass looks better than ever by a wide margin! I HIGHLY RECOMMEND Osorio Irrigation. Many thanks to Wil and his crew for a job well done!"

"Roger and his crew are great. They're where they say they ll be when they say they ll be there, they re courteous and unfailingly nice, they give great recommendations, nothing is ever a secret or an unpleasant surprise, and they work a heck of a lot harder than I m willing to. Roger also took the time to find and arrange continuing lawn maintenance for us. I m looking forward to working with them again- I strongly suspect we ll have some garden design going on for next season."

Lawn Care FAQs, answered by experts

No, it isn’t illegal, but many cities and towns have noise ordinances that it could violate. Either way, it can still cause problems if it bothers your neighbors. For motor-powered lawnmowers, the general consensus for common courtesy is to wait until after 8 a.m. to mow your lawn. However, if you have a push mower, you should be safe to mow at any time of day, provided you don’t make excessive noise in other ways.

Property managers handle maintenance by scheduling routine checks, coordinating repairs promptly, and engaging qualified contractors to maintain property conditions.

St. Augustine is a hardy grass that’s relatively easy to grow, but it requires regular lawn maintenance to stay healthy. It’s best to keep up with a regular fertilization schedule during the growing season, plus a yearly dethatching to help it properly absorb air and moisture. Watering is also important, so be sure to water it enough to keep the soil moist.

The best times to mow your lawn are mid-morning or early evening. Mowing in the mid-morning, around 10 a.m., allows any dew to evaporate so the grass is dry. Cutting dry grass is easier on both the lawn and the mower, and this timing gives the grass blades time to recover in the sunlight before the peak afternoon heat. Alternatively, you can mow in the late afternoon or early evening once the heat of the day has passed. Avoid mowing too early in the morning when the grass is still wet with dew, and try not to mow during the hottest part of the day, as high temperatures and harsh sunlight can put extra stress on the grass.

Avoid watering your plants once temperatures regularly reach freezing temperatures or lower. Water won’t make it down to the roots at that point—it’ll just freeze to the topsoil level.
