TWCA Qualification
|
TWCA uses peer review of objective data collected through multi-year, multi-site trialing to qualify the most drought tolerant cultivars of each turfgrass species.
Qualification in TWCA is time limited and progressive; meaning each cultivar must either re-qualify against a new, higher standard of drought tolerance or lose its use of the seal. In order for a turf grass consumer product, blend, or mixture to be qualified to use the TWCA label, a minimum of 70% of the varieties included in that product blend or mixture must be TWCA qualified. |

Tall Fescuealphabetically
|
Tall Fescue is a hardy and adaptable species of cool season turf that is well known for drought tolerance. Two contributing factors here are an incredibly deep rooting structure and a high endophyte content; the first gives the plant access to a deep profile of moisture in the soil while the second contributes to great pest resistance. A versatile, durable turf, with good drought tolerance; Tall Fescues are found through the majority of the cool season turf range and provide an alternative to warm season turf in many areas.
