Scientists quantified the impact of colorants applied in autumn on zoysiagrass in the transition zone. Persistence of green color increased with application volume, but differences among colorants were limited. Compared with tall fescue, colorant-treated zoysiagrass had significantly higher color ratings for 98-112 days at 80 gal/acre, 112-154 days at 160 gal/acre, and 138-154 days at 240 gal/acre. Results showed that duration of acceptable color on zoysiagrass lawns can be enhanced by increasing colorant application volume.
