"I highly recommend Glacier Irrigation, as Sam and his team have done an exceptional job installing a new sprinkler system on my extensive property spanning over 2 acres. The high-efficiency system they implemented ensures complete coverage and significantly reduces water consumption compared to my previous setup. Moreover, in addition to the sprinklers for the lawn, they expertly installed drip lines for both vegetable and non-vegetable plants. The project was executed professionally, adhering to the agreed schedule and budget. I wholeheartedly endorse Glacier Irrigation for its outstanding work."

"Great Lawns did an excellent job on my sprinkler repair job. David came out to view the problem, diagnosed the problem and gave me a quote to do the repair. I hired Great lawns and set a date for them to come out and do the repair. David and a helper showed up on the agreed on date and proceeded to do the work, it was a pleasure to watch them do the work, yes I watched them every step of the way. They expertly repaired the leak, it was a leaking main valve to my sprinkler system, which was 6 feet underground where it connected to my homes main water line. David made the repairs, tested everything and filled in the hole, which was 5 feet by 5 feet by 6 feet deep. It was amazing to watch an expert work. I would hire David and Great Lawns again in a New York minute, the work was excellent and the cost was very fair. A job very well done!"

Lawn Irrigation FAQs, answered by experts

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

Buffalo grass spreads through both underground roots and above-ground stolons. The widespread root and stolon system makes up for this grass’s overall lack of density. It’s a hearty grass, so it spreads on its own slowly, especially considering that most of the male (no staminate) varieties of grass are sterile. You may think about over-maintaining your lawn to encourage growth, but this would have the opposite effect.

The easiest way to rough up soil to accept grass seed and provide the best opportunity for its growth is to make several passes over the area with a garden tiller and rake away the loosened vegetation and debris. However, in some cases, very hard ground may require using a shovel or pick to break up pieces into smaller chunks that the tiller can handle more easily.

You should put pre-emergent herbicide and fertilizer on your lawn in the spring. Pre-emergent herbicide keeps weeds from taking root. Fertilizer helps your grass to grow lush and dense and blocks future weeds from growing. You can also add amendments, such as sulfur and lime, to enhance your soil quality. 

Post-dethatching, lawn recovery includes watering, fertilizing, and reseeding as necessary to restore health and promote growth.
