Blood Orange Trees
Am buying a blood orange tree. All the trees at this place have thorns from bottom through the top of the tree. I always thought that the rootstock had thorns, but if the entire tree had thorns, that meant the grafted bud had died and only root stock remained. Do blood orange trees have thorns throughout?

It depends on the variety of citrus you are looking at. If both the variety that provided the rootstock and the variety that provides the top of the tree are thorny, the entire tree will have thorns. It is also possible that you are looking at ungrafted trees. Ask whether the trees in this nursery are indeed grafted.
