As a local member of the community, I have been in the construction industry for just over 10 years. With experience ranging from general construction needs, to light electrical, and plumbing I have the knowledge it takes to complete a job on time and with excellent quality. \n\nWhy pay more for a large contractor to provide you a simple service when you can save money and have some peace of mind knowing a local member of the community is taking care of your needs and providing exactly what you need.

Lawn Irrigation FAQs, answered by experts

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.

Always mow the lawn on a short setting when overseeding. The thinner coverage offers more space for the grass seed to take root in the soil. When reseeding a lawn, however, you may need to remove your old turf altogether.

No, watering dead grass will not bring it back to life. If the grass on your lawn is truly dead, no amount of water will bring it back to life. However, some methods can bring dying grass back to life. Consider aerating, overseeding, or analyzing your soil to get to the root of why the grass is dying. 

Yes, it's common for lawns to look bare after dethatching. Dethatching brings soil to the surface to create a "bald" look on your lawn. While you may choose to patch or reseed your lawn if bare patches seem excessive, it's normal for a lawn to look bare after dethatching. With the layer of debris that was blocking water, nutrients, and air from reaching your grass now gone, your lawn is likely to grow better than ever.

When stored under ideal conditions, grass seed lasts anywhere from 10 to 18 months from the testing date without any real decrease in the germination rate. You can still use the seeds after this timeframe, but the germination rates drop 10% to 20% each year. 

If you’re just embarking on an overseeding project, using seeds that have been in storage for a few years isn’t too big of a deal. However, if you’re planning on redoing your entire landscape, your best bet for a healthy, luscious lawn is to use new seeds.
