Concrete edging adds a finished and clean look to your landscaping. Designing and pouring your own garden edging can create the custom look sought after by many gardeners. Working with poured concrete typically requires using molds. Concrete mold forms are available at your local home supply store or garden center. However, the cost can be substantial. Whether your goal is to define a beautiful flowerbed or to create a focal point in your yard, building your own molds is an inexpensive and easy way to accomplish your purpose.
Things You'll Need
Plywood sheeting or bender board
String or spray paint
Wooden stakes
Nails
Saw
Level
Cement mix
Define the area to be edged. Mark the boundaries of the proposed landscape edging using string or spray paint. Consider your options and what will best define the area. Decide whether curved or straight lines are more appropriate to create the look you are trying to achieve.
Determine the width and height of your desired above-ground edging. Following the lines of your boundary layout, dig a trench in the ground deep enough so that the bottom of the trench is below the frost line in the area where you live. In figuring the width of the edging, add the width of the plywood sheeting or bender board to the dimension. For example, if your edging is to be 6 inches wide and the plywood sheeting that you are using for your form is 1 inch thick, use a dimension of 8 inches wide when digging the trench.
Cut the plywood sheeting or bender board. Saw it lengthwise into strips wide enough to take into account the height of the proposed edging plus the depth of the trench. You are creating the sides of the concrete mold. You will need two pieces of wood for each stretch of the trench. Put two wood strips in the trench, placing one against each side of the trench, as you move along the length of your landscape edging. These walls of the mold will hold the concrete in place until it sets.
Hammer the 2-by-2 inch stakes into the ground. Place them on the outside of the molding walls. Nail a stake to the wall every 12 inches. This will keep the walls of the mold firmly in place during the pouring and setting of the concrete. Check to see that the walls across from each other are level along the length of your edging project.
Pour the concrete according to the manufacturer’s instructions. Allow the concrete to set completely. This may take one or two days, depending on the weather. Carefully remove the walls of the concrete molds and the stakes when the concrete is completely dry.
