"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

Yes, you can overseed your lawn without aerating it, but results may vary. If you have the time, dethatching or aerating your lawn before overseeding will yield the best results. Overseeding your lawn without aerating will work, but less seed will take root. For the best possible results, aerate your lawn before overseeding it.

You can fill the holes weeds leave behind with soil or sand to avoid unsightly spots or tripping hazards. If you remove weeds from a grassy area, fill the hole with soil and grass seed, and water regularly to promote grass growth.

Seeding a lawn offers several advantages over laying sod, primarily related to cost and variety. Seeding is less expensive upfront, making it a more budget-friendly option. It also provides a much broader selection of grass varieties, allowing you to choose the best type for your specific climate and soil. Additionally, seeding allows grass roots to establish directly in the native soil, and the installation process is typically less labor-intensive than sodding. However, it's important to consider that sod offers better immediate protection against weeds and erosion.

Hiring a professional lawn care service is generally worth the cost, especially if you have limited free time. Lawn care professionals can ensure your lawn receives the vital nutrients it needs to grow and thrive, guaranteeing a healthy, beautiful, and well-maintained yard with professional-looking results. While some homeowners enjoy doing the work themselves, hiring a company frees up your schedule. The decision also depends on your budget and whether you already own the necessary lawn equipment, as doing the maintenance yourself can reduce monthly costs. Additionally, many lawn care companies offer other services like snow and leaf removal to keep your property in top shape year-round.

Post-seeding care involves regular watering, mowing when appropriate, and occasional re-seeding to cover sparse areas.
