Aerial roots are one of the very useful and impressive features of some fig trees. As with other design elements of a bonsai the aerials must augment the overall design scheme.
In this Ficus virens the aerial root crosses across the trunk and in addition it gives the appearance of a reverse taper to the trunk of this tree. It could be removed or a better option is to move it to the other side of the trunk and use it to improve the taper of the trunk.

The moved aerial is wrapped with sphagnum moss and placed into the soil. Within several weeks new hair roots will form on this aerial and make it a permanent fixture of the design.
