A sideprofile of an Easton Carbon One arrow with a spine of 900, taken with a scanning electron microscope (SEM). The arrow is a bond of two carbon tubes, an inner and an outer tube (black wires). In between both carbon layers, another fiber is used (white fiber). This second fiber is an Mg-Al-Si-fiber.
Mowing: Bermudagrass performs best when mowed between Â¾ and 1Â½ inches. Begin mowing as soon as the lawn turns green in spring. Always leave the clippings on the lawn in a practice called 'grass-cycling'. Grass clippings decompose quickly and do not contribute to thatch.
Mowing heights may range from 1 to 3 inches depending on the frequency of mowing and the degree of shade present. At mowing heights below two inches, St. Augustine grass should be mowed every five days during late spring and summer. At a 2 1/2 inch mowing height, a 7-10 mowing schedule is adequate. Above 2 1/2 inches, St. Augustine grass should be mowed at 10 to 14 day intervals. In moderate to dense shade, St. Augustine grass should be mowed at about 3 inches at 10 day intervals. During the fall, mowing height should be raised about 1 inch to increase total leaf area of the turf. The increased leaf area will help the grass accumulate energy reserves to get through the winter.
