tree. The image created is one of a tree growing out of the side of a cliff with the

tree cascading downwards. A cascade can have a small head of upward growth.
As the natural tendency for trees is to grow upwards it can be very difficult
to encourage vigour in a bonsai that is forced to grow downwards. Cascades are
often attempted by beginners for their striking shape but it is rare to see good
quality full cascades.
The cascade form is split into two variants, the full cascade has a tip that falls
below the bottom of its pot, the semi-cascade is broadly speaking any tree whose
trunk ends between the base and the rim of the pot. The semi-cascade form also
includes trees with horizontal trunks that terminate at the roughly the same
height as the rim of its pot. As with slanting forms, the roots should appear to
anchor the tree with bigger, stronger roots on the opposite side to the lean of the
trunk.
