FWIW, I am hesitant on burlap now. I have had only one experience and it wasn't good. I purchased the product from Dayton Bag and Burlap; recommended for the application of seeding. I seeded with Rye and fertilized a small area around our spillway pipe. The seed sprouted very well, but the rye couldn't push thru the mesh of the burlap. The only places it pushed thru is the immediate vicinity of the wire stake/staples we used to hold the burlap in place.

Underneath each pillow of burlap in the pic was a bushy stand of fresh Rye grass. We wound up cutting the burlap at each staple and leaving the small circles of fabric to rot. The 85% balance of the burlap was tediously removed, trying not to tear up the new grass seedlings. Suk'd.
