Roy, a reader of this blog successfully transplanted a Dracena Draco (Dragon Tree) and was kind enough to send me some photos.

How to successfully support a transplanted Dragon Tree

Roy wisely protected the Dracena Draco from damage by using padding. The white marks on the branches can be avoided by gently removing leaves only when they are ready to come off. Tearing them off prematurely results in these white marks which then reduce the beautiful stripping on the plant.
