✶ A very good way to use a split rail fence in landscaping is to install a simple two rail split rail fence along the perimeter of the garden. If your garden is large, then you can install the split rail fence on one side of the garden that does not overlook the street. The long horizontal lines of a split rail fence, give the illusion of a larger space. To make the garden look attractive, plant large shrubs along the perimeter of the fence.
