"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

Common options include Kentucky bluegrass, fescue, and ryegrass. Choose based on climate and lawn usage.

While hydroseeding is typically meant for bare soil, it is possible to hydroseed over an existing lawn with some adjustments. For the new seed to germinate and thrive, it needs good seed-to-soil contact. Without it, most of the seed may not take root and will die. To improve your chances of success when repairing a patchy area, mow any existing grass as low as possible and loosen any exposed soil before application. It is also recommended to use a finer mulch mixture when spraying, as this will help the seeds reach the soil and root without suffocating the existing grass.

Soaking grass seeds in water before seeding is called pre-germinating. It’s not necessary but can be very helpful in some cases. Some grasses like are very slow to germinate, and basic seeding on the ground is unlikely to be effective—that’s especially true of cool season grasses like Kentucky bluegrass, rye grasses, and Bermuda grass. Soaking these seeds in a bag or bin of water for one to four days beforehand can give the grass the start it needs to survive.

Each season’s climate influences approaches needed for effective suppression.

Grass will grow back after being sprayed with vinegar. If you’re looking for an alternative to chemical herbicides, vinegar can help you manage weeds. Use a mixture of 1 gallon of white vinegar, 1 cup of salt, and 1 tablespoon of dish soap to spray on your grass. This will kill the grass at the surface while keeping the roots intact, so it’ll eventually grow back. You’ll need to use an herbicide or manually remove the whole root system to get rid of grass for good.
