A softer stone than granite, limestone is nonetheless a durable edging alternative. Using limestone in areas that receive less foot traffic, such as along garden beds or on the sides of wide walkways, will increase the longevity of the edging. With its pale-colored, rough-textured appearance, limestone can create a striking and vivid contrast to foliage from your garden or lawn. Available in a number of different finishes and size options, limestone can be customized to suit your edging needs.
Limestone pavers, when first purchased, come in unfinished flat slabs of different sizes. The edges can be shaped and rounded to give the pieces a softer, finished look. In the case of edging, rounded tops are useful as they do not create as stark a contrast as the sharper flat-edged slabs. Limestone can also be shaped to make a flat-topped curved edge for winding walkways or circular garden beds. In some cases you can purchase pre-shaped pieces of limestone for edging purposes, or, if you prefer, you can shape them yourself at home as the rock is fairly soft.
As limestone most frequently comes in flat square pieces, this edging option for limestone is less time-consuming to execute. Square or flat limestone edging has the added benefit of being easy to mow over, so the pieces are well-suited for edging walkways that border lawns rather than garden beds. Square limestone pieces can also be installed on their sides to create a 45-degree angle edge that juts out above ground, for a more eye-catching edge design.
Most limestone comes roughly textured when first purchased, particularly when they are bought as large slabs to be cut and shaped by the customer. However, polished limestone adds an elegant touch to your landscape design, with the pale, lightly streaked appearance of the limestone becoming more pronounced with polishing. Polished limestone is more frequently purchased rather than done by hand at home, and features one or all sides of the often square-edged pieces buffed to a high shine. Use polished limestone to edge walkways to create a more refined appearance.
Crushed limestone is perhaps the easiest to install, requiring little effort other than filling in a shallow trench where you want the edging to lie. Maintaining a crushed limestone edging is more time consuming, however, as the rocks can easily be knocked out of place. One of the benefits of crushed limestone is that can easily fill in a border or edge of any size or dimension. Lining the trench with landscape fabric where the limestone edging will be placed will help ensure the crushed pieces do not get embedded into the soil.
