How to Make Lightweight Concrete Garden Pots

Updated February 21, 2017

Container gardening is an easy solution for longtime gardeners facing new physical challenges including arthritis or back pain. Containers allow you to elevate your plants to chest level so that you do not have to bend or stoop. But the weight of large, heavy containers can make lifting a challenge. You can solve this problem in a couple ways: lighten the containers by adding plastic foam packing peanuts to the soil or lighten the pots themselves.

Cut PVC coated fiberglass mesh into 3-inch-wide, 24-inch-long strips using a utility knife.

Mix water and liquid cement dye according to instructions on the dye package. Slowly mix dye mixture with Quickwall concrete until the mixture is the consistency of toothpaste, typically this is one part concrete to two parts water.

Coat strips of fiberglass with cement mixture and apply to them to the sides of the cooler as if making papier mache. Press concrete mixture through the mesh and into the surface of the cooler. Apply strips over the lip of the cooler and throughout the inside.

Smooth Quickwall over the surface so that no mesh is visible.

Mist one side of the container with water and cover that side with plastic. Wait two to three hours. Then, leaving the plastic on the first side, turn the container and repeat this procedure on a second side. When the entire surface is covered with plastic, let the cement cure for 24 hours.

If your lightweight concrete garden pot needs a second layer of cement, repeat all steps.

When your garden pot is finished, paint or stain it before planting.
