Pennington's Straw Blankets are an excellent way to establish and encourage new growth when laying seed. These wheat straw blankets enhance seed germination dramatically by protecting the seed, holding the seed in place, controlling weeds and retaining moisture in neutral and challenging areas. Pennington Straw Blankets are the most effective method to preventing erosion and washout, particularly in areas with hills and slopes. They can also be placed around foundations to protect new masonry from mud splatter stain. Once your seed has begun to grow in, your Pennington Straw Blankets will naturally start to degrade, leaving you with amazing results.
