Which planting method involves placing rhizomes or stolons in trenches and then packing soil?

• A. Sodding
• B. Sprigging
• C. Plugging
• D. Hydro Seeding

Answer: (B)

Sprigging is a vegetative turf establishment method where pieces of the plant such as rhizomes or stolons are placed in shallow trenches and then the soil is packed over them. This packing secures good soil-to-tissue contact and keeps moisture close to the propagules, helping them root and grow quickly. It’s a common choice when you want faster establishment than seed and when the plant spreads via underground or above-ground runners.

Sodding involves laying pre-grown turf slabs directly onto the prepared soil, not working with trenches or packing over propagules. Plugging uses individual small plugs inserted into holes, rather than laying material in a continuous trench. Hydro seeding disperses a slurry of seed, often with mulch and fertilizer, over the soil surface rather than using rhizomes or stolons.
