Landscape stakes are a biodegradable installation tool to secure coir mats, straw blankets, and erosion control products. Erosion control stakes break down over time, reducing the amount of maintenance required when erosion control blankets are used. Made with recycled plastic and an additive that changes the polymer structure, the biodegradable landscape stakes will last 24 to 36 months.
Landscape stakes hook into the ground and stay put. Once the landscape stakes are installed, they will begin to biodegrade. To make sure that the erosion control stakes break down while being used, they should be completely submerged in the soil and away from secondary exposures to heat, sunlight, and chemicals. The breakdown process will turn these plastic landscape stakes into piece of carbon and plastic particles, which will eventually break down into carbon dioxide, water, and biomass material. Typically, landscape stakes will last anywhere from 24 to 36 months, depending on your site conditions.
