Creeping bentgrass has better submersion tolerance than Kentucky bluegrass.

Creeping bentgrass has better submersion tolerance than Kentucky bluegrass.

• A. True
• B. False
• C. Not sure
• D. It depends on water depth.

Answer: (A)

Submersion tolerance is about how well a turfgrass survives when the root zone is flooded and oxygen in the soil drops. Creeping bentgrass is well adapted to wet, poorly drained conditions; its root system and growth habit help it stay metabolically active and recover more quickly after flooding. Kentucky bluegrass, while versatile, tends to suffer more from prolonged oxygen deprivation in saturated soils and recovers more slowly, showing greater decline under submersion. Because of these physiological differences, creeping bentgrass generally handles submerged conditions better than Kentucky bluegrass, making the statement true for typical field situations.
