One of the coolest features designed and built by Details Landscape Art, a Sonoma County landscape contractor, are dry creek beds. We install them as a means to cover and disguise otherwise unattractive French drains, and also as a way to break up a large garden area into smaller sections.
Always snaking and meandering along its length, the dry creek bed consists of rock and ornamental grasses in a natural looking formation. Once the shape of the creek bed is excavated, usually only six to eight inches deep, we plant various size grasses both in the creek bed and along the banks. Then a drip irrigation line is dropped into the bed, and all the grasses dripped. Larger moss-covered boulders are the next element, again – varying sizes and shapes- and installed both in and along the banks of the entire length. We tuck rocks in and around the grasses and group them in clusters.
Once the grasses, irrigation and boulders are in, the bed is then filled with smaller rock. We use a mixture of 1 ½ inch, ¾ inch and cobbles, usually in grey and brown tones. River rock, trinity, and Sonoma Valley cobble are stone types we typically use.
Dry creek beds are a very interesting feature, usually with an Asian flair, that adds a nice touch to a garden.
