DIY Concrete Modular Wall Planter

These concrete modular wall planters made by Ananda at A Piece of Rainbow are the perfect geometric accent for the modern home. And with a little know-how and a dose of patience, you can recreate them on your own. Simply follow the instructions below and you’ll have the beginnings of your own living wall to hang in your bedroom, bathroom, or anywhere else you please.


– Pourable concrete mix, such as Quikrete 3000lb (used here)
– Cardboard or thick card stock for making the molds
– Template for the molds, formatted for 8.5″x11″ – download template
– Plastic containers
– Plastic bags
– Box cutter or scissors
– Glue and tape
– Gloves
– Dust mask


DIY Concrete Planters - cardboard

Print and cut out the template, trace onto cardboard, and cut out the inner and outer molds. The template for the outer mold on page 2 is larger than 8.5″x11″, so rotate it when you trace to complete the shape. Score, fold and tape each mold with scotch tape or masking tape. Fold 3/8″ wide strips of cardboard into triangular shapes and glue them to the inside bottom of the outer molds. These will function as drain holes and openings for hanging later.

Screen those really big chunks of aggregates out of the Quikrete 3000lb mix- a plastic nursery pot works great, and leave some small aggregates for strength. Mix the concrete following the proportions recommended on the bag, using the screened concrete as if it is the original mix. Wear dust mask and gloves when working with concrete.

Pour the mix into the outer mold till it’s level with the triangular pieces, then place the inner mold inside, making sure it is centered. Pour the walls using a popsicle stick to help pushing the mixture down.


DIY Concrete Planter - dry

Let the planters stay in the molds and cure for at least 3 days by misting them daily and wrapping them in plastic bags. This is a very important step to ensure that the concrete hardens as much as possible so they don’t chip or break. The more moisture you can keep in the plastic bag the better.

After day 3, take the planters out of the molds. Since concrete is very alkaline and that can be a set back for plant growth, soak them in a tub of water for a day and let dry. I decided to paint the edges with gold acrylic paint for an added sense of mystery.

Now we are ready to plant. Succulents are great because they are easy to care for. Give the plants a couple of weeks to form roots that hold the soil in, and now we can hang or stack these planters to create our own mini vertical gardens! To create a pattern on the wall, use the template to mark where the 3 openings on the bottom of each planter are, and use 1 or 2 nails/screws for each planter depending on the pattern you want to create.
