I'm using rubber mulch from lowes $9/bag, or Wally world $7/bag....go w/ the dark brown if you like or the "reddish" ....the stuff I got orriginally from Lowes was stringy and looked just like shredded wood, subsequent bags were smaller chunks...blended in well so I don't care... It is soft and looks sharp.
best regards,
Dave
Hows that rubber mulch holding up color and smell wise? Any sign of termite interest? Thats about the same price as the rocks from my local gravel yard but looks a hell of a lot better.
