What is the planting method called when rhizomes or stolons are placed in trenches and covered?

• A. Hydroseeding
• B. Sodding
• C. Plugging
• D. Sprigging

Answer: (D)

Sprigging is a vegetative planting method where pieces of the plant that can grow roots—rhizomes or stolons—are laid in shallow trenches and then covered with soil. The buried portions come into contact with soil moisture, root, and produce new shoots, spreading to form a dense turf. This approach is used because it establishes turf using existing plant material, typically at lower cost and with faster establishment than seeding, though not as quick as laying sod. It’s different from hydroseeding (spraying seed), sodding (laying full-grown turf mats), and plugging (inserting individual plugs).
