Sod is grown on specialist farms. For 2009, the United States Department of Agriculture reported 1,412 farms had 368,188 acres (149,000.4 ha) of sod in production.

The square foot gardening method recommends using an open-bottom raised bed, 4 by 4 feet (1.2 m × 1.2 m) square. The square beds are then divided into a grid of sixteen one-foot squares. Each square is planted with a different crop, and based on the plant's mature size either 1, 4, 9 or 16 plants are placed per square.
Historically, much of the shrub-steppe in Washington state was referred to as scabland because of the deep channels cut into pure basalt rock by cataclysmic floods more than 10,000 years ago. Major threats to the ecosystem include overgrazing , fires, invasion by nonnative species, development (since much of it is at lower elevations ...
