Bowling Green has sodding farms, which sell sod. A sod or a turf is an expanse on which grass for lawns in grown. A turf is basically a layer of grass and its roots held together as a thin layer. This is grown on specialist farms. It is grown locally so that the turf doesn't get dried out when being transported. The kind of grasses grown can vary, and can be selected based on the choice of appearance and texture (as desired by the customer). Sales are held periodically. The land on which turf is grown can be used again after harvesting the grass, approximately about 18 months after sowing. The dimensions of the turf have to be very exact. They are typically harvested in small slabs, square slabs, rolled rectangles, or large 4-foot-wide (1.2 m) rolls. It can be used for ladscaping and lawn repair in Bowling Green.
