How to Make Concrete Planters
Design a patio or garden you will be proud of, by displaying your plants and flowers in unusual concrete planters that you designed. This one of a kind container for the deck, porch or front door, is solid and strong enough to hold a shrub or small tree. Use as a centerpiece in your back yard or close to your kitchen for planting herbs.

1
Cut the plywood into the size you want your pot to be. Nail the sides and bottom, drilling a one inch hole in the center of the bottom to allow for drainage. Build another box that will be placed inside the larger box to form the inner wall. Also, drill an identical drainage hole and be certain to allow a space of two inches in between to form the walls.

Insert the plastic pipe into the hole of the larger form and spread the prepared concrete mix evenly at the bottom. Apply a coating of oil over the entire outer walls of the inner form. Place the form directly over the pipe and into the outer box.

Pour the concrete mixture into the space completely around the walls, tamping carefully to prevent air pockets.

Wait at least 24 hours before removing the mold. Allow the concrete planter to remain damp, by loosely wrapping it with plastic. This should be left to cure for five to seven days before planting.

Use the forms to make more concrete planters or create other shapes and sizes. Design unusual pots by using large strong containers. A waste basket filled with sand or rocks, placed in the outer form, would certainly be an original design.
