What is the least costly lawn?

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

Answer: (D)

The main idea here is how the cost of establishing a lawn is driven by material and labor. Seeding is the least costly method because the seed itself is inexpensive and the installation requires less material and labor than other methods. Sodding uses mature turf laid in place, which adds a high material cost and more work to fit and joint the pieces. Plugging involves planting many small root plugs, which increases both material and labor compared with seed. Sprigging uses stolons or rhizomes cut and planted, which also adds more material and handling than seeding. So, even though seeding may take longer to fill in and establish, the upfront cost is the lowest, making it the most economical option.
