In your experience, what's the best mulch you have found for resisting wind? What I'm talking about are those little wind tunnels that seem to form around the corners of a house or in between houses in close quarter subdivisions. Is there a technique that you've found that helps? I try to make sure that all edging is at least 4 to 6 inches deep and will apply 3 to 4 inches of mulch, usually triple shredded bark. And yes I know that I should consider mulch that blows away an up $ell opportunity and all that, but just wanting to know.
