Fruit Tree Nursey in south LA that are not grafted

What wrong with a grafted tree? The root stock will not give you good fruit if grown into a tree and the grafted "top" does not have as strong of a root structure. Best of both worlds in one tree.

There is a wholesale nursery called Bracy’s in Folsom LA. I believe they still do fruit trees

Just so you understand, grafted trees, particularly citrus, are grafted for a reason. The primary reason is growing fruit trees from seed produces an unknown quality of tree. When we graft, we take a "pure" specimen of known qualities and graft it to a strong rootstock. A seed will be the offspring of 2 parents, potentially producing a less desirable tree. Since we won't know the quality of the tree and fruit for possibly several years if grown from seed, we skip ahead and start with the quality tree we desire.

FWIW, I'm just an old jarhead, so I may not know what I'm talking about.
