Despite a rock garden’s upfront cost, you can find some rocks for free to help stay within budget. You may find free stones where they’re a nuisance to someone else, like on a farm or construction site, and are bound to be thrown away. Talk to a local farmer or construction worker, and you may have a new rock to bring home. Rock hunting in your yard is also an excellent solution to finding small stones and pebbles for free. Grab a bag or container and make a day out of finding the most exciting small rocks for your rock garden.
