Here rock is good for winter but the summer heat burns up plants .I like the rubber mulch but it is expensive and heavy rains we get wash it away real easy .On a different note everyone knows I did my decks over and built new pergolas and well I bought behr stain in transparent cedar color .Well it goes on darker and seems very waxy like and you have to stir every time you put the brush in your paint bucket .It separates really fast and you can't overlap the slightest bit .I don't think I will be using it on the decks.Plus you need to put it on very thin or or it looks terrible ,I will show my boo boo's also .I should have went with olympic elite .I will upload pics ,At least some of my boo's are hidden .No pro here but oh well
