Today we have a local contractor spraying our pinestraw beds. I am doing this as an experiment this year. If this product can help me preserve pinestraw all summer long without having to freshen up areas mid summer, it will be totally worth the expense. Pinestraw is a lot like wood decking. Over time, the sun breaks down the pinestraw and considerably fades the color. This product coats the straw and protects it from the elements. We did a small 10' x 10' area last fall in front of the office. It looked great this spring. I am looking forward to seeing if this is effective.
