This is a review of the curlex 1 erosion blankets. I did a mazama reno last year and had 2 steep hills and a runoff area where i used the erosion blankets. Ultimately the blankets held the seed better and also held the tenacity in place better as well as you can see by the severe poa outbreak surrounding the blanket strips. I wish i had done the entire yard. Better germination. Less weeds. Less washout as i has severe washout and seeded multiple times in the non blanket areas. If you are doing a reno i would absolutely use these blankets on slopes or if you anticipate thunderstorms or washout. The blankets dont need to be removed and that was a concern as they seemed puffy. Totally broke down by spring
