You plan to fail when you fail to plan was something that some wise person said sometime ago this is an excerpt from patio and stone by. I really like it because it kind of lays down how to set boundaries in your landscape with walls and the choice in walls and what people like and what looks good for the goals that you have
The Following is a great excerpt to help understand from the Book "Patio and Stone" by Tom Wilhite on Bricks on page 114-115:
"A garden is really just a little piece of the natural landscape that has been set aside for cultivation. In fact, the word "Garden" is derived from an old German word meaning and closure. A fence or hedge can certainly enclose a space, but a stone wall carries a certain psychological haft along with its visual weight and appeal. A wall also blocks noise and wind, providing a feeling of Refuge from The Busy World Beyond. In the case of a retaining wall, the soil itself is kept at Bay.
This same sense of enclosure can be repeated with in the garden. A stone wall might separate a driveway from alarm, a patio from a pool, or a Rose Garden from an area where kids play. Even a low Stonehedge edging around a raised vegetable bed says, plants inside, path outside.
Give careful thought to the fact that the materials will have on the character of your wall. Large, dark fieldstones murdered in place make for a massive, substantial ball, whilst acts and Colour flagstones make a wall appear lighter and less imposing. Brick walls have an orderly, traditional look, while walls of stucco or painted concrete look more contemporary. Of course, you will want your wall to relate to the architecture of your home, particularly if it is near the house.
Garden walls can be expensive, so it's worth researching your options thoroughly. Landscape designer Scott Columbo says, "I would almost always prefer a stone wall over a fence or head, but cost can become prohibitive, even on higher-end projects. Still stone walls are by for one of the most beautiful garden elements when designed and built properly.". Landscape designer Cameron Scott adds, if you're on a budget, install a partial section in a prominent location and fill it around it with a hedge or fence. Also remember that a wall need not the tall to have a big impact. In a small garden, it's better to keep walls fairly low, they'll offer a sense of enclosure without making you feel like a prisoner.
Landscape architect it can often uses low walls as a transition element. "These work particularly well in the front yard, also providing vegetable ground for a homes for sale. I find that an 18 inch high stucco or stone wall breaks up a planting area so that a front lawn does not seem as necessary. This type of low wall acts as a boundary and adds the sense of another destination."
