Adding new turf blend soil to a new lawn will be critical to the new lawns growth for many years. Preparation is the most important stage when installing new sod. We suggest a minimum depth of 3 inches of new soil over top of an old lawn base, meaning over top of a soil that would be reasonable for growing in. If you are starting new 6-12 inches would be ideal.
New soil for new sod allows the roots to penetrate deep into the sub layer below. Having a strong root system in your turf will allow the plant access to water, nutrients and oxygen all things your new lawn needs to keep healthy.
It is wise to always purchase new soil anytime you are laying a new lawn from sod.
