"Hard working individuals that totally exceeded expectations in every possible way. As an example, I moved a trailer for them so they could park their truck next to the gate and when they completed the job they put the trailer back. This is customer service that you never see anymore. They removed limbs from my trees and when they were completed it was not one leaf left on the lawn. Amazing job"

"We had another company install our sprinkler system 3 years ago and it wasn't done correctly. We've given many times to correct it and they couldn't. Bryan from this company came out and immediately knew how to resolve all the problem spots and fix the heads to spray how they needed. Not only is he excellent at his job his customer service is awesome. He went above and beyond to make sure we were comfortable, happy and understood the best way to manage our lawn. This company is blessed to him on their team!!"

Lawn Irrigation FAQs, answered by experts

The amount of time it takes for grass to germinate varies depending on the grass species. Even after germination, it’s going to take a while to see grass blades start emerging from soil. Some grasses germinate quickly and emerge after several days of growth (and healthy watering). Others may take up to three weeks to show themselves. Cool-season grasses tend to take the longest to germinate at one month.

Properly preparing the soil for planting grass seed may include applying fertilizer several weeks before spreading the seed if you plan to overseed the lawn. However, in most cases involving a brand-new lawn, spreading a starter fertilizer along with the grass seed will give it the best chance of taking root quickly and growing strong.

If thrown on the ground and left, some Bermuda seeds will sprout on the surface, but you will have a diminished germination rate. It’s best to cultivate the area before spreading the seeds for optimal results. Rake the area first and then evenly distribute the Bermuda seeds. Cover the space with about ¼ inch of soil before watering the area.

The best hardiness zones for St. Augustine grass are USDA growing zones 8, 9, and 10. However, with a bit of extra attention, it'll also grow well in zones 7, 11, and 12.

It’s best to fix lawn depressions during late spring. You want to wait until after your last frost date and when the yard is not too wet. This also allows ample time for new grass growth once you reseed.
