Many years ago I attended a lecture by a well-known garden designer who was emphatic about the need to understand the edges of a property before you embark on a landscape plan. This was more than just understanding the location of the property lines, or compiling an inventory of trees, plants, and other structures — both essential to the design process.

The premise was to create a clear framework of well-chosen trees, shrubs, fencing and other appropriate hardscaping for that garden perimeter. In essence, to envision an appropriate perimeter. By starting at the edges, the overall intent or scheme of the garden will present a framework that will suggest how the rest of the garden will evolve.
By removing all weedy overgrowth, the backbone of a good design is revealed such as existing ledge, retaining walls and previously hidden shrubs and perennials. (Click for a larger view.)
