How to Cast Concrete Planters
Create colorful and creative DIY concrete planters for your container garden with these easy step-by-step instructions! Customize your containers to get the perfect size, style, and color.
Want to add interest to your container garden? Try making your own concrete planters! Disposable containers, such as small milk cartons and 4- to 6-inch nursery pots, work well as outer molds for pots; reusable plastic tumblers from the dollar store prove fitting as inner molds. Flexible plastic molds work best. Rinse molds and tools thoroughly so they can be reused.
Estimate the amount of premix needed for a few pots by filling the molds with dry premix, then pouring it into a plastic tub for mixing. We prepared a batch of concrete and pink concrete pigment (either Tea Rose, Blush, or Morning Mist by Direct Colors) to make several pots at a time in each color. You don't have to add pigments to the concrete—without it, the planter will be an off-white color.
