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.
1 To find out the optimal height for your grass, see: Getting to Know Your Lawn table. For example, common bermuda grass can be allowed to grow on average of up to 2 1/2 inches before its first mowing. To determine your mower height, see: How High Should I Cut my grass?  Be careful the first couple of times you mow.
