"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."

"David and his son, David (Great Lawns Landscaping) upgraded a very old distribution box of our irrigation system, which was installed personally by a previous owner, so that it would operate like a brand new system. They took on a job that most irrigation contractors would only shake their heads. Not only did they intelligently determine how to make a tricky repair, but they did it right away at a very reasonable cost. They will be my first choice for irrigation issues in the future. I highly recommend them."

Lawn Irrigation FAQs, answered by experts

Costs depend on property size, service frequency, and additional tasks like aeration or overseeding.

Having a luscious lawn won’t take a century to grow with hydroseeding—most hydroseed lawns sprout within 7 to 14 days. Once the new grass is about 4 inches tall, which is about six weeks after the installation, it’s ready to mow. After the initial mow, keep foot traffic at a minimum for another four weeks to solidify the rooting system.

Choosing between sod and seed depends on your budget, timeline, and maintenance preferences.

Sod:

  • Pros: Provides an instant, lush lawn and immediate curb appeal. It's more resistant to weeds and erosion, can be installed any time during the growing season, and offers a consistent appearance.

  • Cons: Has a higher upfront cost, typically $0.90 to $1.80 more per square foot than seed. It offers fewer grass varieties and must be installed immediately upon delivery.

Seed:

  • Pros: Less expensive upfront, making it a budget-friendly option. It offers a wider variety of grass types and is easier for a DIY installation.

  • Cons: Takes much longer to establish, potentially up to two years for a full lawn. It requires more maintenance, including regular weed control, and is more difficult to cultivate.

Ultimately, if you want a beautiful lawn quickly and have a larger budget, sod is an excellent choice. If you are patient, want to save money, and prefer a wider selection of grass types, seeding may be the better option.

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.

Treating dry soil can bring back a dormant lawn, but not a dead one. After nurturing a dry lawn back to proper moisture levels, you should closely observe whether your grass revives with the soil. If not, you may need to reseed your lawn or start fresh with new turf.
