Raft Style –
Ground Layering styles

The raft styles are characterised by a single trunk growing along the ground, with several trunks growing from it. In a basic raft style, the trunk is perfectly straight and illustrates a tree in nature that has been blown over by the wind, taken root and the branches on the upward side continue to grow as new trunks.

A variation the sinuous style is very similar, however the trunk going along the ground may be curved; this style can be created using a tree with one-sided branches, by laying down the side without branches onto the ground.


Tree laid on its side and branches on lower side removed


When there is a bend in the trunk, place it so that it curves towards the back; this will give a three dimensional effect. Any horizontal branches may be ground layered and then trained upward to form trees. Some branches will be pliable enough to be bent, while others may need to be undercut with a wedge shape wound in order to train them up vertically.

Remove any branches from the underside of the planting; wire all remaining branches normally. Be very careful on the removal of this wire at the first transplanting it may otherwise become entangled with the newly forming root system and hence later, become very difficult to remove.

Bark underneath upward growing branches is peeled back and dusted with rooting powder;
the branches are wired to the position and shape they would be as “new” trunks.


Probably a better method of wiring is to place a heavy wire along the top side of the laid down trunk, attach it with string in a few places and then anchor the wires for each branch individually onto it. Another alternative would be to wire each branch individually with double wire looped once around the prostrate trunk. This too however, can interfere with root formation.

The technique for producing roots on the underside is reasonably easy.


When sufficient roots have formed, remove from
growing-on box and place in a bonsai pot or tray.

Since some species root more readily than others, it is possible that areas which had been cut and dusted with rooting hormone will have healed over rather than generated new roots. If this has happened, simply repeat the procedure and use less hormone powder this time. It is better to choose quick-rooting varieties for creations of this style. Junipers and Salix are particularly accommodating more so than varieties such as pines that are far slower to produce roots.
