O.F. Wolfinbarger has been serving the Upland, California area as a trusted supplier of landscaping products for the better part of a century now. With a long and storied history in landscaping supplies and building products, we've built a solid foundation of excellence and are excited of the reputation we sustain in the region.

When a business has enjoyed success for over 90 years, there is likely a good reason for it. At O.F. Wolfinbarger, our success story started off four generations ago when our patriarch Olin borrowed $350 from the bank to buy a truck for hauling cow paddocks. What started off as an casual business transaction between a farmer and a dairyman has since grown into one of the leading providers of landscaping products in the Southern California region. At the heart of our business is our custom soil mixing. This service was born out of necessity when neighborhoods began moving into the once-barren foothills of the region.

Why Choose O.F. Wolfinbarger Inc. As Your Trusted supplier of Landscape products? We're popular among homeowners, businesses, and building materials companies throughout the area. We'd love to add you to our long list of satisfied customers. Find out for yourself why we're the go-to place for landscaping in the area.
