Adding boulders to the landscape designs can be enjoyable and can give a distinct look to your outdoors. Boulders add a natural element to landscape designs and create year-round visual interest by providing structure and a backdrop for plants. There are several landscaping ideas with boulders. For instance, landscaping with boulders for your water features offers many benefits, in addition to having a focal point to build around. Stack them together for water to trickle down in a waterfall or create a natural deeper pool in an existing stream. Line a fish pond with them for nutritional moss to grow on to help feed the water creatures.
