Grass roots play the most important part in a healthy lawn.  Without extensive grass roots your grass would not be able to intake water and vital nutrients that it needs to survive.  If you are installing sod for a new lawn, remember that in order for the sod to get to your house the roots of the grass must first be cut.  Cutting grass roots removes some of the plant’s ability to harness water and nutrients.  This is why watering your new sod is so important in the first few weeks.  Shallow grass roots are not able to reach moisture buried in the soil.  It takes sometime for cut grass roots to start working their way in the soil again.

Grass Roots

Get longer grass roots by seeding your lawn.

With all things considered being the same, if you take a sodded yard and put it next to a seeded yard you can see a difference.  Seeded yards will usually tolerate a lack of moisture better because they have a more advanced root system.  The grass roots are usually never the same once they have been cut.  From our experience we have found grass roots in seeded lawns are deeper than those of lawns sodded at the same time.  You might even notice a color variation between the two areas even if they are fertilized the same.  Grass roots play an important part in nutrient uptake as well.  The more roots and the deeper the roots, the better chances that moisture and nutrients can be found and directed to the plant.  Seeded lawns may not provide an instant lawn, but the long-term benefits are worth the wait.  Sodded lawns are not bad at all, but keep in mind the trauma caused to the roots when the sod was harvested.  Sodded lawns may require more of your attention to keep your grass looking it’s best.
