"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."

"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 questions, answered by experts

For optimal results, water newly planted grass seed at least twice a day—once in the morning and again in the late afternoon. The goal is to keep the soil consistently moist for the first two weeks, but be careful not to overwater or flood the seeds. After about two weeks, you can reduce the frequency to once per day. Always monitor weather conditions and adjust your watering schedule accordingly; for instance, you won't need to water as much if it rains.

DIY solutions often lack precise formulation and distribution, potentially leading to lawn damage. Professional treatments optimize results with targeted applications.

You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

This depends on the type of grass seed, as some types do better in different environmental conditions. Cool-season grasses go dormant during the summer months when the soil temperature exceeds 65 degrees Fahrenheit. Once exposed to regular doses of heat, the germination rates decline, with seedling death not far behind. 

As for warm-season seeds, they come from tropical parts of the world and thrive in heat. They actively grow in warm air temperatures between 70 and 90 degrees Fahrenheit, and they prefer soil temperatures between 65 and 70 degrees Fahrenheit. Once temperatures dip and frost rolls in, if you don’t store them properly, warm-season grass seeds will die quickly.

Yes, in most cases, grass will return after your dog urinates on it. But without preventative measures, there’s always a chance your dog will pee on the grass again, leading to brown patches come summer. This aside, even if your grass is dead in patches, simply reseeding the dead spots should help restore your lawn. 

If you choose not to reseed your lawn, unaffected grass surrounding the dead patches will spread over any dead spots. But be prepared for this option to take longer—you likely won’t be able to grow grass fast.
