|There are large roots underground of the orange tree. I'm wondering if these roots are from the orange tree or the tall viburnum shrubs that are just behind the orange tree. I thought that orange tree roots grow straight downward. The reason we know the roots are there is because my husband deep waters the orange tree by poking a rod down deep. Thanks.

|In general, roots extend out past the canopy of a tree. Orange trees are no exception to this. You may find the roots extend one and one half times the diameter of the canopy. While orange trees develop a deep root system, they also have lots and lots of surface roots. Viburnum shrubs follow this same root growth pattern - extending their roots out one and one half times a long as the longest branch.
