An air rooting shell comprises a first shell half mateable with a second shell half to form a shell for enclosing around a branch. The shell comprises a reservoir for containing planting medium and an upper lipped opening that receives the branch and collects and funnels water to the reservoir. A bottom opening is provided through which the lower portion of the branch may exit. Side openings on the shell may be used to enclose a branch in a horizontal orientation, while the upper lipped opening remains vertically oriented to receive water.
