These two were my second attempt at making stepping stones for my garden. This time we used a paper towel to give the molds a very light coating of olive oil before adding the concrete. It worked perfectly! These two turned out very well!
Make a Variety of Shapes with Concrete Choose container shapes that complement your garden's style, and make sure plants will have a suitable container in which to thrive. Drill drainage holes into your planters after the concrete has set, or place a cork or piece of foam in the bottom when forming the pots. When you water concrete planters, they will darken, then lighten as they dry.
