Generally speaking, using earth to hold up more earth is not the smartest thing to do. You need something stronger. Yes, you can make a low wall out of any earthen materials, but keep it 18 inches tall or less, preferably without a surcharge (a slope above the wall). Refer to the earlier section "Raising Earthen Garden Walls" for more on creating earthen walls.
One pretty amazing earth technology called superadobe really works for retaining walls, however. Visionary architect Nader Khalili developed a method of filling long fabric tubes with soil and arranging the tubes like a coil pot to make retaining or freestanding walls and buildings. The walls are plastered so the tubes don't show. The strength and longevity of this material are excellent. Visit the Cal-Earth Web site (www.calearth.org) for the lowdown on this extraordinary approach.
