How to Build a Brick Garden Bed


Although planting in the ground is fine, building up a garden using brick can improve your gardening experience. Building a brick garden bed allows you to raise the dirt up from the surrounding area. This gives you a longer growing season, allows you to plant early, and allows you to improve the soil in a smaller space, according to Colorado State University. Using brick gives you a permanent, raised gardening space.

Step 1

Measure out your gardening area and mark the four corners of the space required using stakes and pieces of string tied between them. Make the garden bed no wider than 4 feet so that it can be worked from both sides without stepping onto the soil, says the University of Missouri Extension.

Step 2

Dig a 16- to 18-inch wide and 6- to 12-inch deep trench along the four sides of the garden bed, suggests the Texas A & M website, and fill the area with cement.

Step 3

Hammer a 3/8-inch reinforcement bar into the middle of each side of the garden trench and allow the cement to dry for three to four days. Smooth it out using a trowel.

Step 4

Wet the top of the cement footer and apply a 3/4- to 1-inch layer of mortar along 2 feet of the slab.

Step 5

Push a brick onto the mortar hard enough so that only a 1/2 inch of mortar is visible under the brick and the footer. Spread mortar onto the side of the next brick and set it 3/8 of an inch away from the first brick and knock it into place using the end of the trowel.

Step 6

Continue placing down bricks, staggering each layer until the wall is built on each side of the garden. Remove excess mortar using the trowel to keep the wall clean.
