We constantly drive past fields organized into stripes or checks. I finally found the time to look into how this is done. It’s called lawn striping, and the effect is achieved by bending the blades of grass in different directions.

The direction in which the grass bends determines whether a stripe will be light or dark. When the blades lean away from you, the lawn looks lighter because the light reflects off the broad and long surface of the blade. When the blades lean towards you, the lawn appears darker because you are looking at the tips of the blades (smaller reflective surface) and you see shadows under the grass. Therefore, mowing the lawn in opposite directions (up/down, left/right, north/south, east/west, etc.) creates the greatest contrast between the stripes. Interestingly, since the “color” of the stripe depends on the direction from which you look at it, a light stripe will appear dark if viewed from the opposite side.

This fuss over grass is a very American phenomenon. I overcome my laziness to mow the lawn only when the grass has indecently overgrown (the notion of “indecently overgrown” is also something I adjust each year after receiving tsk-tsk letters from the village administration). My neighbor, however, seems to do it every few days, and I once saw him kneeling in the grass—complaining that someone had dragged something across his lot, dropping some chips in the grass and ruining its perfection. Really, the only thing missing was a pair of scissors in his hands.
