"Outstanding service! Our local lawn sprinkler unexpectedly and without warning stopped providing service, and we were left stranded. I reviewed new candidates and selected Greg Tanzer. Couldn't be more pleased. They were extremely responsive, informative, professional, and very affordable. We will be switching our business to Greg's business."

"An amazing experience for my landscape lighting. From sales to scheduling to installation... All around a terrific experience and one that we’ve become used to with Tanzer. In the past, they've installed and modified our irrigation to perfection as well. The installers didn’t make a complete mess of the property, especially when they were digging the trenches. The sod was put back nicely, which is a HUGE deal for me. And they took their shoes off to go into the basement after working in mulch, grass and dirt. If you're looking for a landscape lighting and/or irrigation professional, they're the BEST!"

"I was having  a problem with water leaking out into the yard from an unknown source. Called several companies (I open the system myself) who said it was probably a defective valve or leaking manifold causing the issue. I asked for a ball park number which ranged from $200 to $325 "depending on what would have to be replaced". I called Quality Irrigation who took the time to ask specific questions on the phone. He came up with the same diagnosis but said with any luck it may be repairable without taking apart the manifold. He came out the next day, literally took the valve apart to find that a stainless steel nut was stuck in the diaphragm causing the value to slow leak and flood the yard. He reassembled the valve, boot up the system and it worked like a charm. He charged me just for his time, $85. I now have a new sprinkler service company! Thank you..."

"The job went great! Prior to installation of the irrigation system, Jimmy worked with my landscaper to ensure the new sod and planting beds we were having installed would thrive. The crew showed up at the agreed upon time and were very professional. The supervisor came by to make sure everything was going as expected and was available to answer any questions we had. They came back to our home two weeks later for a two week follow-up. The technician walked us through the system step by step (again) and made necessary adjustments. Unfortunately, a week after our 2 week follow-up visit we discovered an area of our new sod that wasn't getting enough water. All County quickly responded and sent another technician back to our home to adjust the necessary sprinkler heads. We couldn't be happier with our new irrigation system and would definitely recommend All County Irrigation to anyone looking to make their lives easier by installing an automatic sprinkler system. "

Lawn Irrigation FAQs, answered by experts

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.

The best time to plant grass seed depends on your local climate and whether you have cool-season or warm-season grass.

For cool-season grasses (like tall fescue), the ideal time to seed is late summer or early fall (typically August and September). During this period, the soil is still warm from the summer, but the air is cooler, creating optimal conditions for germination and root establishment before winter. There is also less competition from weeds. Spring is a secondary option, but cooler soil temperatures, the risk of a late frost, and less time for the grass to mature before summer heat can make it less successful.

For warm-season grasses (like St. Augustine), the best time to plant is from late spring through mid-summer (typically May and June), when temperatures are consistently between 75 and 90 degrees Fahrenheit.

In general, it is best to avoid seeding during winter or early spring, as cold soil and air can prevent seeds from germinating. For recommendations tailored to your specific grass type and climate, consider consulting a local lawn care professional.

Aerating a lawn before seeding it or adding new grass seed is a smart decision. By loosening up compact soil and allowing it to take in more air and water, your seeds will have an easier time establishing roots and growing. Aerating beforehand also means your seeds will have better contact with the soil, so more of your seeds have a chance to germinate. If you do plan to aerate your lawn before seeding, aerate about two days before you plan to start seeding.

The first step in re-doing a bad lawn is correctly diagnosing the problem. That’s why we recommend calling a licensed and trustworthy lawn care company that can help turn your damaged lawn around. Once the problem is diagnosed and fixed, you’ll want to keep up with lawn maintenance by watering, mowing, and feeding your lawn the proper nutrients.

While it may seem easier and faster to throw grass seed onto dirt and call it a day, that method likely won’t yield great results. Preparing your lawn for reseeding or seeding by clearing rocks and debris, aerating, removing existing grass, or leveling it. You should also plan out the best time to plant your grass based on its type and your location to ensure it grows well. So, if you want your grass to grow successfully, put more time and effort into the project than throwing seed on the ground.
