Lawn thatch is the layer of dead and alive stems between the green grass leaves up top and the soil down below. Thatch is not made up of grass clippings, contrary to popular belief.Too much thatch restricts air and water movement within the soil.Thatch of Â½ inch or less is not detrimental to lawns, and can help keep moisture in and weeds out.oo much thatch can also keep the soil too moist, and trap fungus and bacterial diseases in this critical layer between the grass leaf blades and the soil.
