Re: Sandy Yard that wont grow grass
It is likely that there is nothing there to feed the grass and keep it growing. Apply 4" of manure or compost, work it to a 6" depth and reseed/resod. Sod has a better chance of making a go of it because it's already green and growing, whereas seed requires quite a bit of care and nurturing before it starts to grow, and a good long while before it's substantial enough to walk on or be considered a "lawn".
