To build a brick flower bed, make a concrete trench, chalk an outline, lay the first course, build the corners, finish the rest of the courses, check the levels and finish the joint with a pointing tool. It takes two to three days depending on drying times.
- Make a concrete footing
Dig a hole that is 1 foot deep and twice as wide as the brick walls are anticipated to be. Fill it with concrete. Add concrete footings every 4 feet, making sure they reach beneath the frost line. Allow it to fully dry.
- Lay the bricks dry
Arrange the bricks without mortar, accounting for the mortar's required space. Use chalk to mark where the first and last brick sit.
- Lay the first layer
Mix the mortar according to the manufacturer's instructions. Lay the first and last bricks, then use a mason's line to check if they're even, adjusting accordingly. Apply 1 inch of mortar along the length of three bricks. Lay the first course, applying mortar to the end of each brick before laying it.
- Build the corners
Lay the corners, making each course one-half of a brick shorter than the previous one below. Swipe the mortar on all four edges of the brick's face before applying.
- Lay the other courses
Using a mason's line to keep both walls completely even, lay the rest of the courses. Use a mallet and brick set to cut bricks to size if necessary.
- Adjust levels and finish joints
Use a mallet and plank to adjust the levels and straighten any uneven courses. When the mortar is firm to the touch, use a pointing tool to finish the vertical joints first and the horizontal joints after. Wipe away any smeared mortar with a damp rag. Allow the mortar to fully dry before using.
