"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."

Jesus was friendly, professional, and easy to communicate with, making the entire process smooth.

Lawn Irrigation FAQs, answered by experts

The best time to plant is between spring and autumn. Springtime weather is typically mild and is when nurseries start to bloom. When the summer weather arrives and it’s hot out, it’s best to avoid planting bare-root plants, but you can still plant many in-container varieties. The first sign of fall is another great opportunity to plant biennials if you live in southern states, or a lovely vegetable garden up north.

DIY is possible with proper tools and knowledge. Professional services ensure even coverage and optimal growth.

Due to its slow growth, Bahia grass does not generally take over weeds. In fact, the opposite can be true. Young Bahia grass is susceptible to being taken over by weeds. 

Likewise, in the cool season, Bahia grass goes into a dormant state that can allow weeds that thrive in early spring to get the upper hand. If you want to prevent weeds from taking over your yard, remove them by hand or apply a Bahia grass-friendly pre-emergent herbicide to your lawn before weeds have a chance to appear.

If your lawn and general landscape are struggling, consider calling a local landscape specialist to suggest lawn amendments, local plants, and hardscape changes to boost the long-term health of your outdoor space. While you may be able to take on small projects yourself—such as reseeding your lawn or testing the soil—a professional can help you build a plan to bring a struggling yard back to life quickly.

The time you should wait before walking on new grass depends on whether you used seed or sod. If you laid new grass seed, it's best to wait about eight weeks before stepping on it, as new grass is fragile. For sod, it typically establishes itself in the ground in about two weeks. For heavy traffic, like driving a car across a new grass driveway, you might need to wait an entire season.
