Question 1

Which soil pH range is generally considered optimal for most turfgrasses?

Accepted Answer

6.0–7.0

Question 2

What is the primary advantage of sodding over seeding when establishing a new lawn?

Accepted Answer

Sodding provides instant, erosion-resistant coverage while seeding takes weeks to months to establish

Answer

Sodding provides immediate ground cover and erosion control, while seeding requires significantly more time for germination and establishment.

Which turfgrass spreads primarily by stolons (above-ground runners)?

Accepted Answer

Bermudagrass

Bermudagrass spreads aggressively by both stolons (above-ground) and rhizomes (below-ground), contributing to its rapid lateral spreading habit.

Question 4

When is the best time to seed cool-season grasses in the northern United States?

Accepted Answer

Late summer to early fall (August–September)

Answer

Late summer to early fall provides optimal soil temperatures for cool-season grass germination and allows establishment before the onset of winter.

Question 5

What is topdressing in turfgrass management?

Accepted Answer

Spreading a thin, uniform layer of material such as sand or compost over the turf surface

Answer

Topdressing involves spreading a thin, uniform layer of material (sand, compost, or soil mix) to improve surface smoothness, thatch decomposition, and soil physical properties.
