I'm trying to get some input from guys who have installed crushed red stone before. The majority of my customers call for mulch and riverstone. This will be the first time i'm using crushed red stone. (1/2" - 3/8" in size) The customer also has plastic edging that was installed when the home was built 5 years ago. In 5 years the ground has settled and in my opinion the edging looks like hell. Picture of the stone: http://www.landcareassociates.com/images/materials/aggregates/large/autumn-red-3quarter.jpg Picture of the edging (Similar style 6' plastic strips, nailed into the ground) http://img.diynetwork.com/DIY/2008/05/13/droc407_3fi_SnapEdging01_lead.jpg I've always taken a spade and dug out the edges for my landscaped mulch beds, and they come out great. I can design the bed anyway I want, and if the ground settles or the edge fades, i'll just dig again or use a stick edger to refresh. But this is with mulch. Would you dig out an edge with red stones, or is a plastic edge needed? Thank you!!
