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

Vegetative Reproduction of Bentgrass for golf courses:
complete final grading
harvest stolons, keep moist
spread over area to be established
topdress
roll
keep well watered

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
Speaker Notes
- Low growing, fine bladed, creeping by long vigorous stolons
- Will stand up well under heavy use provided its aggressiveness is supported by an intense management program
- Use – golf and bowling greens; tees and fairways on high maintenance courses
- Used as a monostand; incompatible with KBG/fesue blends due to its puffy creeping habit at taller mowing heights
- Because of stolons get lots of thatch

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
Speaker Notes
- Poor disease resistance; susceptible to snow moulds, dollar spot, brown patch
- Poor drought tolerance due to shallow annual root system; requires an irrigation system
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
Speaker Notes
- Thatch - partly due to management concerns and partly due to the plant’s stolons.
- It looks out of place in a polystand.
- These disadvantages are outweighed for sports turf by the benefit of mowability, texture, and aesthetic.

Power raking required to ensure water/oxygen infiltration
Seeding Rate: 0.2 - 0.5 kg / 100 sq. meters
Speaker Notes
- High Maintenance - LOW mowing height (2 cm is less than an inch, and that’s the longest) 4 mm!!.
- Water Often, Lots of Nitrogen (the other N pig)
- Requires high level of maintenance; very expensive to look after well - not suited to home lawns

Vegetative Reproduction of Bentgrass for golf courses:
complete final grading
harvest stolons, keep moist
spread over area to be established
topdress
roll
keep well watered
Speaker Notes
- Because getting exact match is vital for playability and aesthetics on the golf course, this grass can be reproduced vegetatively to ensure perfect matching.
- It is a high maintenance practice that would only be employed with very high maintenance grass.
