The greenhouse for grass — since 1985.

Evergreen Turf Covers is the flagship brand of Hinspergers Poly Industries, a Canadian manufacturer that has been shaping how professionals protect and grow turf for four decades.

We invented the modern, lightweight turf cover that acts as a greenhouse for grass — trapping heat, protecting against frost and winter kill, and accelerating germination to just 4–5 days. Our patented SmartEdge lace coating lets crews cut and shape covers on-site without fraying — a small detail that changes how greens get covered.

Today, Evergreen protects turf at some of the game's most storied venues — Erin Hills, Oakmont, Winged Foot, Pinehurst #2, Whistling Straits — and at stadiums, horse tracks and sod farms on multiple continents.
