Why mowing height matters to the grass
Cutting short removes the leaves that feed the plant and shade its own soil.

From the opening
Mowing height matters because the blade is the grass plant's leaf, and cutting it short removes the surface that catches light and feeds the roots. A higher cut leaves more leaf, which shades the soil and lets the plant replace what was cut without spending reserves it no longer has. The opening covers leaf area left after the cut, roots that die back when tops are scalped, and shade on the soil and the crown.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
