Commonly marketed as a creeping bentgrass blend; composition must be verified from the supplied seed label.
Agrostis stolonifera, subject to blend label · Commercial bentgrass blend designation
Profile
- Identity
- Not necessarily one genetic cultivar
- Composition
- Supplier and production lot determine component cultivars
- Use
- Blend design targets fine turf
- Verification
- Retain seed certificate for management comparisons
Water & soil targets
- Moisture (VWC)
- Site-calibrated; measure field capacity and dry-down
- Salinity tolerance
- Component dependent; usually limited
- Drought tolerance
- Limited under very close mowing
Optimal root measurement depth
1–3 in
Putting-green and fine-turf roots are short, especially in summer; read shallow. Typical guidance; confirm with a soil probe on site.
Calibrate sensors in the actual root zone; account for mowing, rooting depth, seasonal growth and drainage before adjusting irrigation.
Problems to watch
- Blend composition changes
- Summer root decline
- Dollar spot
Stress signs
- Nonuniform canopy
- Heat wilt
- Small bleached lesions
Where you'll find it
- Golf greens where label supports use
- Fine-turf renovation
