Hanes Geo Single Net Erosion Control Blanket (4' x 112.5')

Seed on a slope has a different problem than seed on a flat lawn: gravity and the first heavy rain move both the seed and the soil it is sitting in downhill before anything germinates. An erosion blanket is the answer — a straw mat held together by a single net that you unroll directly over the seeded ground and pin down with landscape staples. Once it is anchored, the mat holds the soil surface in place, keeps the seed where you put it, and is listed as retaining moisture through germination while the new grass roots take hold and become the real erosion control. Installation is straightforward: seed first, unroll the blanket down the slope so it lies flat against the soil with no bridging over dips, overlap the edges, and staple it at the intervals the packaging specifies. The staples are not included — order them at the same time or the roll sits in the garage. One roll is 4 feet by 112.5 feet and covers 500 sq ft, and each package holds a single roll, so measure the slope and count rolls before ordering. The listing describes the product as degradable but does not specify the netting material or whether the netting itself is biodegradable or photodegradable; if that matters for your site, confirm it with the manufacturer before installing.
