In addition to many other uses, earthbags also make great privacy walls. Besides being beautiful, privacy walls help block wind and noise, and keep out stray dogs and prying eyes. You can greatly enhance your home using this dirt cheap building technique.
Protected from excess wind, plants can thrive even in harsh climates like New Mexico. In fact, you can create a mini oasis behind privacy walls with proper care and adequate watering. I refer you to a great little book called Behind Adobe Walls: The Hidden Homes and Gardens of Santa Fe and Taos, by Lisl and Landt Dennis. They document through beautiful photographs of luxurious homes how thick earth walls shade plants in heat of summer and retain heat for nurturing many types of flowers and other plants through cold spells.
Unlike straw bale privacy walls that are susceptible to moisture damage, earthbag privacy walls can withstand the elements much better. They take more time to build, but you can make earthbag walls as moisture resistant as you would like by stabilizing the soil fill material with lime. Alternatively, you could experiment with building privacy walls of scoria, which is highly resistant to moisture damage, and lightweight and easy to work with.
And because earthbags are so versatile, you can combine earthbag privacy walls with planters, benches, arbors, trellises and garden walkways to create magical spaces that are only limited by your imagination.
