Slide 1

Turfgrass ID:

Agrostis stolonifera - Creeping Bentgrass

Slide 2

Creeping BentgrassAgrostis stolonifera (A. palustris)

Germination Rate:

10 - 14 days

Slide 3

Creeping BentgrassAgrostis stolonifera (A. palustris)

PROS

Excellent low temperature tolerance

Excellent resistance to ice damage

Most tolerant turfgrass of continuous close mowing

Fine textured, capable of producing a high quality turf with superior shoot density and uniformity

Vigorous stolon growth, roots at nodes offering good recuperative capacity

Slide 4

Vigorous stolon growth!

Slide 5

Creeping BentgrassAgrostis stolonifera (A. palustris)

CONS:

Extremely high cultural intensity required to maintain properly

Varies in colour – greenish/yellow to blue/green, depending on cultivar

Not as wear tolerant as Kentucky bluegrass or perennial ryegrass

High disease susceptibility

Slide 6

Creeping BentgrassAgrostis stolonifera (A. palustris)

CONS:

Prone to herbicide injury – especially 2,4-D; use mecoprop only

Tendency to thatch – above ground stolons in combination with nitrogen

Cannot be used in a polystand with KB because of aggressive patchy, creeping growth habit

Turf becomes very “puffy” at higher mowing

Slide 7

Creeping BentgrassAgrostis stolonifera (A. palustris)

General Use

SPORTS TURF

Widely used on putting greens, tees, fairways

Tennis courts and lawn bowling

Generally planted as a monostand

Slide 8

Creeping BentgrassAgrostis stolonifera (A. palustris)

Management Preferences

Preferred mowing height 4 to 20mm (VERY low)

Frequent irrigation

0.25 to 0.75 of actual N (nitrogen) per 100 sq. metres per growing month (Same as KB - quite high)

Topdressing required to control thatch

Shallow vertical mowing and brushing (verticutting) to control grain

Prefers moist, cool, fertile soils

Power raking required to ensure water/oxygen infiltration

Seeding Rate: 0.2 - 0.5 kg / 100 sq. meters
