I don''t want to replace the one branch that is producing the normal fruit of orange color pulp as a Washington Navel Orange. I think it is neat that this happened, and I want to keep that branch attached to the mother Cara Cara tree. O f course a person could take all the buds from that branch and possibly grow Washington Navels, but why do that. A mature Washington Navel orange tree can be purchased from a dozed suppliers ready to produce fruit.
