When people mention scallop edging in their garden, a lot of people think of painted concrete blocks or small wire fences with a scalloped top. But, before this type of scallop edging became common, many gardeners decorated the edges of their lawns and gardens with small natural fences called wattles. These simple, short fences are highly ornamental and they are simple to install and build. Because you are shaping the fence yourself, you can make the scallops as tall as you like.
Collect a few bundles of very flexible suckers (green sapling wood) and thin branches. You will also need a group of 24-inch sturdy uprights. Sharpen one end of each of your uprights using a gardening knife or axe. You will space your uprights every 10 to 12 inches, so have enough for the length of your lawn.
Drive a piece of rebar 12 inches into the ground. Measure every 10 to 12 inches and make another hole. Insert one of the upright sticks in each hole and hammer it in tightly.
Take a piece of flexible sapling and weave it in and out between the uprights. Form the size and height of scallop that you want to use. Each 5-post upright section is called a hurdle. You can have more than one scallop top per hurdle. Use hemp string to tie the ends of the scallops to the uprights if you are making smaller scallops.
Weave additional sapling branches from the scallop top to the ground. Use gardening nips to trim the tops of the uprights to fit the scallop shape.
