Gardening in places with high winds or constant rain necessitates some permanent flower planters. People with disabilities that limit their ability to harvest and garden greatly benefit from the raised gardening surface of a brick flower planter. Brick flower planters are easy to build and last for decades with little or no maintenance. The most important means of ensuring the permanence of your brick flower planter is by laying a sturdy foundation.
Mark out the location for the flower planter with the stakes and string. Place the stakes three feet apart and tie the string to the stakes. Step back and verify that your outline is straight exactly where you desire.
Dig a trench that is 8 inches wide and 6 inches deep. The trench, which is the outer edge of the flower planter, should follow the string and stake outline.
Rip the plywood board into 1-foot-high pieces with the table saw. Set the plywood pieces into the trench on both sides. The plywood adds stability for the concrete.
Mix the concrete in the wheelbarrow, following the manufacturer's instructions for water.
Scoop the concrete into the trench with the shovel. Fill the trench so that it is level with the ground. Smooth the top of the concrete with a trowel and verify that it is level across the top with a level. Leave it to set overnight.
Pull out the front plywood board, but leave the backboard in place. Fill in the front portion of the trench with dirt.
Mix the mortar in the wheelbarrow using the manufacturer's recommended amount of water.
Fill the mortar bag with mortar using the trowel.
Squeeze the mortar onto the cement foundation and press the first row of bricks into place. Set them so that they are flush with the back plywood piece. Continue stacking the bricks with mortar in between until the planter reaches your desired height.
Fill the top spaces between bricks with mortar to provide a level top surface. Leave the wood in position overnight.
