I have a large swale (corner lot) that I need to prevent erosion on. It's newish construction, and whatever the builder put in there did not take. Doesn't help that we're in a drought (North Carolina).
Where can I, if they've made, buy seed germination blankets larger than 4' x 50'? I see the DuPoint ones at Lowes and Home Depot, but am wondering if there might be a landscaping supply company I could mail order from.
Are seed germination blankets made any larger than 4' x 50'? And can I simply use wheat straw for the walls of the swale/ditch (cheaper), and use the blankets just for the center "floor" of the swale? Seems I'd need lots of blankets, secured with landscaping spikes, to prevent seed and top soil from washing away.
