Wiring a tree into the pot

October 22, 2013 by Jonas Dupuich

Some of the final steps when repotting bonsai are among the most important – especially when it comes to wiring trees into the pot. I typically wire trees into the pot after setting the tree, but when repotting partially or completely bare-rooted trees, I first work some soil into the exposed roots. If no soil is around to hold these roots in place, tightening wires can scrunch roots together, collapsing the rootball and making it difficult to secure the tree firmly in the pot. As I bare-rooted about a third of the roots of the tsukumo cypress below, I filled in the areas between the open roots and around the rootball before starting with the wire.

There are several approaches to wiring bonsai into pots, each with their good points depending upon the application. For this tree, I used my default approach for posts with four holes. Taking hold of the front left wire, I brought it to the point where the front right wire emerged from the soil.

Bringing the wire across the front of the rootball

Where the wires meet I twist them together by hand. If I want to make sure the wire is particularly snug at this point, I use pliers.

If there is a single take-away from this post, let it be this: pull, then twist. If you have ever repotted bonsai with Boon Manakitivipart, you’ve doubtless heard this phrase. The idea is that when tightening wires, first pull the wires tight, then slightly release the tension while twisting. Simply twisting soft wire like aluminum is an easy way to break it. The alternative: pull, then twist.

1. Pull wires away from rootball

2. Lower pliers while twisting

The pull, then twist, approach may be repeated until the wire is snug. After securing the first three wires, you may notice you have nowhere to attach the final wire.

Where does this one go?

Sometimes I plan ahead by preparing a short section of wire with a loop that I can fit around the first wire.

As I didn’t prepare this bit ahead of time, I can do it after the fact with a short, hooked section of wire.

Hook

I hook this wire under the base of the first wire and then twist it back onto itself.

Adding this tail let’s me connect the first wire with the final wire. For this final connection, I always use pliers to ensure the tree is well-secured to the pot.

The last connection

Tightening this last connection ensures the wire is tight across the entire rootball. Once the wire is snug, I remove any excess strands and fill the rest of the pot with soil.

Two more quick steps – more on that Friday – and then it’s time to water.

    For pots with 4 holes are there 4 wires ?
    Couldn’t see what you did with the third wire before you hooked the last one to the first.
    Thanks.

      Hi Frank – this may help a bit: http://bonsaitonight.com/2012/02/24/how-to-wire-a-bonsai-pot/

    Do you ever place a piece of “thin sized” aquarium air tubing over the wires where they come in contact with the roots?

      Hi Wally – yes, I do often use aquarium tubing, especially when the wire crosses roots close to the rootbase. I certainly could have used the tubing in this case but I don’t expect the larger root I crossed to be visible.

    Thank you, although I’ve been doing bonsai for years, I have never been completely satisfied with my wiring. Your statement of ” If no soil is around to hold these roots in place, tightening wires can scrunch roots together, collapsing the rootball and making it difficult to secure the tree firmly in the pot.” explains why. Thanks

    I’m still lost. Does the third wire get connected/twisted into the same connection with #1&#2 wires, so you now have all 3 in one “twist-up”?
    Thanks again.

    Hi Frank – I don’t know if I can explain this well without another photo or video, but I’ll give it a shot. If wire 1 connects to wire 2, 2 to 3, and 3 to 4, there is no good way to connect 4 back to 1. By adding a new piece of wire around the base of wire 1, we can connect wire 4 to wire 1. This approach creates a loop around the base of the trunk.

    I’m making a note to provide more details in a future post. Here’s another attempt to describe the same technique: http://bonsaitonight.com/2009/12/18/repotting-a-trident-maple-securing-the-tree-in-the-pot/

    Thanks Jonas. I think it finally sunk in. I was taking wire # 1 and joining it to wire #2 at the half-way point between the two. That screws up the whole procedure doesn’t it. Much better this way. Thanks again.
