O.F. Wolfinbarger has been serving the Upland, California area as a dependable supplier of landscaping merchandise for the better part of a century now. With a long and storied history in landscaping supplies and building products, we have built a sturdy foundation of excellency and are proud of the reputation we maintain in the area.

When a company has enjoyed success for over 90 years, there's 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 informal business transaction between a farmer and a dairyman has since grown into one of the top providers of landscaping materials 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 area.

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

5 star ratingI called several places looking to buy bark in the old school medium chunks.  It seems that every place I called only had the stuff that looks like Gorilla hair.  My wife hates the look so she called around to various nurseries and a couple of places told us that O.F. Wolfinbarger was the only place to buy it locally. 1 scoop was enough to do most of the areas I needed coverage and was less than half the cost of buying it from The Home Depot.Great place to go if you soil amendment stuff.
