TWCA Qualification
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. For any variety to qualify, it must pass multiple screenings of scientifically repeatable drought stresses, and score at or near the top of any statistical analysis base.
Once qualified varieties retain their qualification for a maximum of eight years (sixteen years for Kentucky Bluegrasses). After the qualification has expired, varieties must requalify against a higher standard of drought tolerance making the TWCA qualification process a series of incremental reductions in overall water need for turfgrasses.
