What are Landscaping Boulders?

A boulder is any rock larger than 10 inches. You might be thinking boulders have to be huge, but they just need to be rather large. Some are small enough to carry, while others will require special equipment to move.

While no two boulders are the same, they are categorized as either angular and round. Round boulders tend to be smooth, while angular boulders tend to have jagged edges and flatter surfaces.

Choosing the right size, shape, and color for your boulders will ensure you get the landscape you desire. There are plenty of great options for your outdoor area.
