Cascade
In the cascade style the trunk starts by growing upward from the soil, then turns downward abruptly, and reaches a point below the bottom edge of the container. For this reason, the container should be placed on the edge of the table, or on a small stand (Figures 7 and 8).
The cascade style has most of its foliage below the soil surface. This style is representative of a natural tree that is growing down the face of an embankment. Training a tree in thecascade style takes longer than in the slanting style.
Choose a low-growing species instead of forcing a tree that normally grows upright into an unnatural form. Bend the whole tree forward so one back branch is vertical and the side branches fall naturally.
A cascaded planting usually looks best in a round or hexagonal container that is higher than it is wide. The tree should be planted off-center from the cascading side.
