I was asked to demonstrate at the recent 2019 New Zealand Bonsai Association National Show and Convention. I decided to talk about Weeping or Pendulant trees as these trees are quite scarce in New Zealand at show level. There was only one weeping style tree in the National Show, a native Kowhai tree.
Below is a video of the presentation that I used. I started off by talking about the biochemistry and the role of geotropism (movement or growth caused by gravity) and the effect of that on auxins in the tree to allow branches to grow downwards. Next was a few slides of weeping trees in nature to show the most important principle of building an upwards growing structure first before you look at the weeping parts of the tree. This was followed by slides of relatively well-developed weeping style Bonsai trees.
I also showed a Willow tree from a cutting, a nursery sourced weeping Beech tree and another nursery sourced weeping Bottlebrush. I talked about wiring the main structure and then also the use of guy wires and objects to hang off the branches to pull the branches downwards. It also included examples of fishing line with weights attached and even the humble clothing peg to act as weight to help gravity do its thing.
