Pine straw vs shredded bark mulch
I am on a homeowners association board. We have been spending a great deal of money on pine straw mulch. I am satisfied with how it looks, but we also have an area that we cover with shredded pine bark mulch. It also looks good, but I am wondering which will last the longest, which will be best for improving the soil as it breaks down, and which will retain moisture the best. In other words, which will give us the most overall benefit or "bang for the buck"?
