Q.Can mesquite tree and Mexican bird of paradise grow together
Can a mesquite tree and a Mexican bird of paradise grow in the same spot? I have two saplings that decided to grow next to each other, a Mesquite tree and a Mexican red bird of paradise. Well, I planted the bird of paradise sapling and then I noticed the Mesiquite pop up about two weeks later. Both are doing very well and I was concerned about them being so close (about 10 inches apart) should I move one and which would be the best one to move?

Yes, I would recommend separating the 2 plants.
They both should be fine to divide as they are still quite small.
Here is links with growing information.
