O.F. Wolfinbarger has been serving the Upland, California region as a respected supplier of landscaping products for the better part of a century now. With a lengthy and storied history in landscaping supplies and building materials, we have built a sturdy foundation of excellence 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.

What started off as an informal business transaction between a farmer and a dairyman has since developed into one of the top providers of landscaping products in the Southern California area. At the heart of our business is our custom soil mixing. This service was born out of necessity when communities began moving into the once-barren foothills of the region.

5 star ratingJust had a great experience at Wolfenbarger.  Needed a specific kind of landscape rock (pyrite), and was not able to find it at other material centers.  Wolfenbarger has a large selection of rock, including pyrite.  Price was right too.  Thank you!
