"Glacier Irrigation went above and beyond to install a new 11 head 2 zone irrigation system with a Rachio timer. This was a new instal that required piping ran in the house to the main line. Sam, the owner, used the best available equipment to instal the lines outside so they did not tear up the grass like all other installers would do. He uses high efficient sprinkler heads to get proper coverage without eating into the monthly water bill. Sam has an excellent plumber, Liberty, who he uses to complete any of the plumbing that needs to be done from the house to outside. The best part of Glacier irrigation is the communication you will receive from Sam. So many companies don't answer their calls, but he is responsive and quick to give an appraisal. I will continue to recommend Glacier irrigation to anyone looking for their lawn to come back to life."

"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

The best time of year for power seeding depends on your local climate. The soil should be warm, but the air should be cool. If the weather gets too hot after you grow new grass seed, it can die off easily. The best time for power seeding warm-season grasses is late spring to summer, and the best time for power seeding cool-season grasses is in the fall.

The fastest growing grass seeds are Bermuda grass, which is a warm-season grass and ryegrass, which is a cool-season grass. Both of these grass types tend to germinate in five to 10 days. Other fast-growing varieties include perennial Ryegrass and fescues, all of which have unique characteristics and growing requirements.

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.

There are several best practices you can do to keep your lawn looking healthy. Knowing when to water grass is among the most important. Having your sprinkler timer set to early morning is best because it gives your grass and plants enough time to absorb water before the sun and wind can evaporate it. To maximize a sprinkler’s impact, aerate your lawn once or twice per year. Doing this achieves better absorption and stronger root systems for your grass.

Like most plants, the seeds need water, optimal temperature, sunlight, and oxygen. Each variety of grass seed will have slightly different needs—higher or lower temperatures, for instance—so pick one that syncs up with your home’s climate and the time you wish to plant. Take a look at the 10-day forecast to ensure there won’t be a major rainstorm.
