Methods of preventing straw from blowing, or alts.
We are running into more and more commercial bids that are requiring a method of preventing the straw from blowing off the property. Since we do strictly commercial landscape projects, the bidding is real competitive, hence we need an economical method of keeping our seed mulched.
I have never seen a hydro-seeder in action, so I'm not sure how effective or cost efficient they are.
I have also heard of using tackifiers being used. Again, not sure of the method to spread it or cost.
The 3rd method I have heard of using is crimping the straw into the ground with a disk. I have seen these before, but it seems to only crimp the straw into the ground every 7 or so inches, and in-between there the blown on straw just blows away in the wind eventually.
Netting is out of question obviously due to cost.
What would be the most cost efficient way of making sure the mulch stays on the ground and doesn't blow away? If you have alternatives to what I listed, go ahead and mention them.
