A lot of the grass in my yard can easily be pulled out, roots & all. I have a lawn service, yet all they can tell me, is its the type of grass I have & that it will come back. There’s no way this grass can come back if the roots are dead & the grass can easily pulled out. They did check for grubs & said there were done. What are your opinions on this?
I would take some samples to your County Extension Office and see if they can determine the type of grass you have.
They can also help you determine an appropriate turf for your region.
