Things You'll Need
Quick dry cement
Don't worry about the exact angle that you set the first brick. A higher or lower angle is totally acceptable.
Bricks can be used as landscape edging to create a border for a flower bed. Bricks set halfway into the ground and on a 45-degree angle provide an edging suitable for most garden landscaping designs. A brick border around a flower bed provides a breaking point between the lawn and flower bed. The bricks also help to contain mulch.
Dig a trough where you want to place the bricks. The depth of the trough should be half the length of the brick. The width of the trough should match the height of the brick. Press the dirt down firmly on the bottom of the trough; pressing your clenched fist may be all that is needed. The head of a sledgehammer could also be used to firm the bottom soil.
Hammer a stake at each end of the trough. Connect a string to the stakes, ensuring that the string is above the ground one-half the length of the brick. This string will be used to ensure the bricks are installed level with one another. If the length of your trough is greater than 10 feet, you may want to use additional stakes to support the string.
Mix the quick setting cement. Working with about 5 feet of the trough at a time, pour the cement into the trough to a height of 2 to 3 inches. The cement does not need to be level.
Place the first brick into the trough on a 45-degree angle and leaning against the end of the trough. Place the next brick into the trough and lean it against the first brick. Use the string as a guide to determine whether the two bricks are level with one another. If not, press or pound the brick into place using a rubber mallet.
Continue placing bricks in the trough, leaning them against the next brick. As you finish one section, add cement to the next section and continue the process of laying the bricks at a 45-degree angle.
Allow the cement to cure according the manufacturer's instructions and then press the sides of the trough against the bricks.
