Weeping Bonsai Trees – NZBA Convention Demonstration and Talk

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.

The interesting thing is that many people spoke to me afterwards to tell me about their weeping Bonsai trees and even about going to have another look at taking cuttings from Willow trees, probably the easiest of trees for this style.

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.

Creating a Windswept Style Bonsai

This Juniper was dug from a friend’s garden two years ago and it struggled to get to grips with life in a pot. The main reason could be that there is quite a bit of rot at the base of the tree and the live vein is quite narrow at that point. The main focus was to strengthen the roots through Proper soil maintenance, fertilising and having a disciplined approach to watering.

After a previous blog post I was inspired to design a Fukinagashi or windswept Bonsai tree. https://bonsaiplace.net/2019/04/21/fukinagashi-windswept-bonsai-style/

As most of the branches were leaning towards the left, it was an easy decision to let the flow all go to that side. A few more weak branches were cut and jinned. This job took about two hours with the help of a knife and a Dremel. The tree was left overnight and lime sulphur applied the following day.

Wiring was applied on the right hand side to enable those branches to be twisted to the left. The tree will now rest and be planted in a very shallow slab, tapering to the left as well. The base will be planted to the far right of the pot. Until then, fertiliser will be applied and the tree will be placed in full sun to maximise growth. Fine wiring will come later during winter. I do believe in little bits more often, rather than doing a lot of work in one go and risking the health of the tree.

Newbie Bonsai Help.

It is very common to see a photo of a seedling or small nursery stock on social media with the following comment: “I am new to Bonsai, please help with advice”. Where to start? What the follows is a number of people writing one liners or a bit more with a genuine interest to help.

I have been demonstrating and teaching Bonsai now for many years and am following what I think is a logical series of steps to enable the new Bonsai enthusiast to work towards a specific goal. It is almost paint by numbers, but in the absence of knowledge and skills, it is the best way to get the basics across in a short period of time. Here are the steps:

  • Unearth the topsoil to look at surface roots.
  • Determine the front of the tree.
  • Decide on a natural flow of the trunk dependent on the style envisaged.
  • Decide which branches / side shoots to keep.
  • Remove excess branches and foliage.
  • Some of these can be selected for deadwood (jin).
  • Create Jin.
  • Wire main trunk if required.
  • Bend trunk to desired shape.
  • Wire branches into position.
  • Clean hanging foliage up.

Each of these steps require a lot of knowledge to get to the end result. This is part of the conversation as the design unfolds. Small nursery material can take up to three hours to style with a new enthusiast in a workshop situation. The hands-on work takes only about thirty minutes to complete, but the explanations and answering of questions, in my mind the most important part, takes up a lot of time.

This Juniper is nursery stock and is 20cm high from the top of the soil. It has been standing around here for a year or so and received very little attention.

The first step is to scrape some of the soil away to see if there are any prominent, larger roots that can help to make a decision about the front / viewing side of the tree. In this case it only contained a whole lot of fine fibrous roots.

It is therefore now up to the trunk line to give an indication of what could be a possible front. For newcomers, we usually look for good movement and flow.

Once the best angle is determined to show things like flow and movement as well as taper or interesting features, it is marked and excess branches and foliage can be removed to reveal the trunk line. The conversation at this stage will include things like removing branches growing from the same height, branches on inside curves and crossing branches.

Some of the branches are identified as possible deadwood branches and these are kept a bit longer. Bark is then removed.

All of these steps have cleared the path for the trunk to be wired. Just the basic of wiring is explained and demonstrated at this stage as this skill is seen as a bit more advanced for a newbie. I think it is important to allow the person to start on their wiring pathway as it is an integral part of Bonsai design. As said, we stick to the basics at this point. It is more important to talk about design and flow at this point.

The branches can now be wired.

The next step is to place the branches in position while a conversation about safe bending takes place. Overall tree health is emphasized at all times. Once the placement is done, excess foliage, especially those growing downwards or upwards is removed. The concept of foliage pads is also touched upon. I find it is important to at this stage point things out like depth (back branches) and negative space. These are all explored ta more advanced workshops.

The last part of the workshop is focused on future growth, the role on foliage in feeding the plant (photosynthesis) and then the very important aftercare of the tree. Protection of small buds and the removal of older foliage as the tree buds over the next few months is discussed as well as feeding requirements and protection over the next month or so.

Potting, root management, carving, severe bending and more advanced wiring techniques are all part of more advanced techniques to be covered at advanced workshops.

Siberian Elm – Ulmus pumila

This little Elm had a huge ugly cut right at soil level when it came IMG_2951into my possession a year and a half ago. This was carved quite deeply to get rid of and then it was extended upwards to try and get a more natural look. The carving was further worked on today. The large carving at the bottom has weathered well and the shari extending upwards from here was made deeper as well as fine carved with a Dremel. A small carving was done on the back where another large (not as large as the front one) cut was made. This resulted in a hole now going through from the back to the front. It is quite high up near the apex.IMG_2953

The leaves have now all dropped and it was decided to work on the carving a bit more and then to also pull the branches on the left down a bit. The flow is to the left. The branches on the right will be kept short and at the next repotting, the tree will be slanted to the left slightly and it is leaning to far forward at the moment.

I have not seen too many of these around and treat it as I would any other Elm. The leaves are still very large and with proper pruning it will hopefully get smaller. The bottom left branch will also be left to grow as it needs to get some width on it.IMG_2956
