Pennington Straw Wattles are easy to use and ideal for many uses such as garden beds, borders, inlets, storm drains, construction sites and more. They can be used in your gardens to define and contain your raised garden beds as well as retain moisture for vegetation. Pennnington Straw Wattles can also be used for erosion control as they stabilize the soil and divert the water flow. The wattle filters the water, capturing debris and sediment while also reducing the speed of the running water. The straw is 100% biodegradable and the netting degrades over time with exposure to sunlight - heavily shaded areas will take longer to degrade due to the lack of UV exposure. Stakes should be placed every 3-4 ft. to keep the product in place.
