Japanese Elm Bonsai are my favorite variety of Bonsai to work with. I love the way the leaves respond to trimming and allows to create amazing branch and foliage structure. Can be fairly easy shaped with wire. However not quite as bendable as Ficus, Branches wire well. On the other hand the trunk would be very difficult to shape on a mature tree. Japanese Elm respond well to trunk chops, this brings more cambium to the surface of the trunk encouraging new growth closer to the bottom. Essential for creating proper taper.
Japanese Elm Bonsai Trees do excellent indoors with supplemental lighting and proper ventilation. I will be posting pictures soon of best bonsai's indoor bonsai growing project. Which is in the works.
