How to Garden Box Planter Concrete Molds – 48″ x 48″ Boulder Rock

• Create the top coping cap / ledge in a number of ways:
• We have a specially made Rubber Edge Liner Form (sold here) just for this purpose!  It can be used in a form, but was designed to be screwed right to your garden box outer form (wood frame).  Some consideration should be taken to assure your securing it is adequate- a few screws probably won’t hold it securely once filled with concrete, so use a bunch or back it with some 2×4 braces if you aren’t sure!
• If you can pour the garden box base first, then you can come back and set up a Plastic Countertop Form (sold here) and one of the Rock Liners to go in it, and then pour the cap.
