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. learn more about TWCA Qualification
