Nitrogen-fixing bacteria for mesquite trees

Zone North Little Rock, AR, zone 8A | mikewholikesflies added on August 10, 2019 | Answered

I have started 2 honey mesquite trees from seeds. Recently, I read that mesquite trees have root nodules for nitrogen-fixing bacteria. I am in AR, far from the Southwest deserts. Will my soil have the proper bacteria? Is there a commercial bacterial mix that would innoculate mesquite trees? Would regular nitrogen fertilization replace the nitrogen-fixing-bacteria?

Do not fertilize these trees. They will fix nitrogen despite having the proper bacterial colonies, although they will likely find replacement colonies just fine. They are very widespread, and if you can grow peas in your area, then you can grow these.

Though a good mix if beneficial microbes will help. These can be found at many gardening centers, or online with the help of Google.
