Hawthorn double trunk Bonsai style progression
This case study shows the collection of a Hawthorn tree and its training as a double-trunk style Bonsai. After being spotted the tree was chopped back significantly and left to recover. About a year later the tree responded well and started growing strongly again. In order to force the tree to grow a dens root-system a trench was dug around the tree, cutting through its thickest roots.
Picture 1: The original tree.
Picture 2: Almost two years after its discovery the tree was finally dug out and planted in a terracotta pot. The tree was now regularly pruned in order to develop a fine branch-structure.

Picture 3: Four years later, after twice-yearly pruning and wiring, the tree developed well. It is 67 cm (27’’) tall.
