"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

Orchard grass seeds can spread quite easily, traveling with the wind as well as birds and animals. Common grass seed packets, especially in the popular tall fescue variety, may contain the occasional orchard grass seed by accident. Always purchase high-quality turf grass seed without "other crop seeds" mixed in.

Germination varies with grass type and climate, generally taking 7 to 21 days. Full lawns develop over a few months.

Depending on the lawn treatments, the best times of the year to redo your lawn are between mid-August and mid-September for overseeding and renovation treatments. For areas such as the southern United States, lawn aeration works best during the fall, when the temperatures begin to drop. Otherwise, early spring is your next best bet because the grass is fresh and ready to absorb nutrients, and the temperature isn’t hot enough to fry the grass and the renovation materials.

While it’s possible to grow grass seeds by throwing them down, this isn’t the best way to plant them. By amending and prepping the soil beforehand, you’re providing optimal contact between seed and soil for a better chance at germination. If you throw them down without preparing the soil beforehand, seeds are more likely to blow away, get eaten by hungry birds, or never grow.

Fescue grass is a relatively low-maintenance grass type, meaning it doesn’t require much more attention than regular watering, dethatching, and mowing. Some fescues even grow slowly enough for hard-to-reach areas, particularly those inaccessible by the mower. Following a seasonal maintenance schedule will help your fescue lawn stay green, healthy, and durable for years to come.
