Roundtree offers multiple varieties of beautiful rocks and boulders including Moss Rock, Granite, El Dorado Blue, Lilac Boulders and Lava Rocks. Our landscape boulders are perfect for retaining walls, ponds, landscaping accents, dry creek beds and waterfalls. Roundtree Rock & Gardening carries the largest inventory and variety of landscape boulders in the Greater Sacramento Valley area. Our customers can visit our yard and enjoy personally hand selecting each boulder for their landscape projects. Boulders can be delivered using our dump service or we also offer boom truck delivery and placement for larger rocks 2’x2’ and up for an additional charge (minimum purchase required). With the use of a boom truck we can place your rock a distance of 10’-30’ depending of the access and size of the boulders. Boom truck service is usually not available for backyard delivery.
