have a full head of hair, you don’t put sunscreen on top of your head because your hair protects your scalp. The same goes for long grass; it provides shade for the roots and soil. Long grass
also develops a deeper root system which makes the grass more fit for dry and less fertile soil. So it is important not to cut your grass too short so that the roots stay protected.
