Can Honey Mesquite trees be transplanted.

It likely could be moved. However, a tree that size will require a tree spade.

Out of curiosity, why would one living in Texas (I am from Texas) want to go to the expense and trouble to move a mesquite? They are relatively abundant and seedlings should be easy to find.

I was thinking that I would get a larger tree faster with the transplant. I'm not against seedlings, and after doing some research I see that they grow pretty fast with the right amount of water. Which way would be the best. I do have access to some pretty heavy equipment, so I don't think the large tree would be out of question.

I would go with a seedling or at least a younger tree. Mesquite are also fairly short lived.

Is there a difference between honey mesquite and western honey mesquite? I've seen several mesquites in southern texas and around the san angelo area that have a form more like an oak tree rather than a bush. I can't imagine some of those trees not being at least a century old.

A smaller transplant will get established quicker in the new site. It will overtake teh larger transplant fairly quickly. Save your back and plant a seedling.
