This multi-functional tall L-shaped grass-stone isolation strip is manufactured from high-toughness flexible PE plastic in fresh matte green, perfectly designed to separate lawn grass, decorative gravel, bark mulch, planting soil and pavement for neat layered garden layouts. Each full roll features a 5cm wide horizontal base and 15cm extra-tall vertical baffle, with a total length of 10 meters to cover large flower beds, tree rings and long walkway borders. Evenly distributed petal-shaped pre-punched fixing tabs run along the top edge, matched with 30 dedicated ground spikes for stable, quick installation.Soft bendable PE material can be freely shaped into curves, circles and irregular outlines to fit any garden design. The heightened vertical barrier effectively locks soil and gravel in place, thoroughly stops invasive grass root spread and prevents cross-contamination between different landscaping materials. Waterproof, UV-resistant, crack-proof and fade-proof to withstand year-round outdoor sun, rain and frost. Its vibrant natural green tone blends seamlessly with lawns, shrubs and all pastoral outdoor planting styles.
