The cascade is on the most basic a style patterned from plants and trees that grow above and on the sides of mountains and steep cliffs. These trees are noted for their downward bending position, which by nature is caused by a number of factors, including falling rocks and snow.
The challenging part about the cascade is that bonsai, knowing that they only are grown in pots, are a bit harder to be shaped in a way that their branches and trunks are going downward. The tip of the cascades are even directed to reach the bottom of the pot’s base, for it to give an impression of a natural tree growing above a cliff that is pulled against the forces of nature and gravity. In this way, it is typical for a cascade bonsai to appear with branches that seem to be seeking for light. The winding of its trunks are also viewed by many as somewhat similar to that of a stream that flows down the edge of a mountain.
The cascade style available for bonsai is divided into two types.
The first division is known as the full cascade, while the other is the semi-cascade. In full cascade, the miniature tree grows with its trunk rising upward from the earth. It turns downward in an abrupt manner once it reaches its maximum height until it touches the bottom of the pot base. If this happens to your bonsai, it is recommended by several experts that the pot should be transferred into an area where the cascading form will further continue. Placing it at the side of a table, or on a small stand could be perfect for such aim.
The semi-cascade, on the other hand, is noted particularly for its trunk that grows upright for a particular distance. From that distance, it cascades down less abrupt than that of the full form. So what you can notice in this type is its trunk that curves, but in a way that it does not reach the base of the pot. It should only be grown just beneath the surface of the soil.
Recommended Species of Bonsai: For the cascade, you can take a prostate juniper, star jasmine, wisteria, chrysanthemums, cherries, cedars, and willows. These plants tend to grow in this form if done right.
Techniques Recommended: It is important to note that for the plants or trees to grow cascading, they should be placed in a narrow and tall container. Also, the main trunk should be kept wired for it to grow downward abruptly. Other than that, a close emphasis to the horizontal and uniform shape of the plants should be taken into consideration, and for the plants to grow successfully according to this style, it should be planted or positioned right into the midst of the container. This is applicable for both the full and semi-cascade forms.
