Yaupon holly – before and after

Posted in Before and after, Bonsai Development by Jonas Dupuich on May 21, 2013

For the past few years, I’ve been refining a Yaupon holly with an eye toward showing it at an upcoming Bay Island Bonsai exhibit. It’s now one of my better candidates for our upcoming 15th anniversary exhibit.

The work at this stage involves letting new shoots run for a time, and then cutting them back to within the desired silhouette. The progress is subtle, but necessary if I am to create branch pads with good definition.

Of course, well-defined branch pads are still a ways off. In the meantime, I’ll continue repeating the grow/cut routine and see how the tree looks this winter.

Large cryptomeria air layer – part 2

Posted in Bonsai Development by Jonas Dupuich on May 17, 2013

Sixteen months into a layering project for a large cryptomeria, it was time to separate the layer (see “Large cryptomeria air layer – part 1“).

September 2012 – time to make the cut

Over the previous nine months, roots had grown to fill the makeshift pot, pushing the soil almost half of an inch above the edge.

Below, the original cut was plainly visible. This is where I’ll make the cut.

I didn’t worry about cutting too close to the base of the new roots as leaving a stub allows me to rest the trunk on the bottom of the new pot, relieving pressure from the new roots and adding stability.

With a little cajoling, I popped off the old pot. Here’s the view from underneath.

Lots of roots

Roots everywhere

I lightly combed out the new roots growing on the surface of the soil and around the edges so the roots could find purchase in new soil. I didn’t remove additional soil as there was nothing but good soil and root-mass within.

From here, I treated the layer like a normal rootball and tied it into the new pot with wire.

For further stability, I fixed two wires to a high branch.

It felt great to finally place the tree on a bench. In another year or so, I can actually start the bonsai work. This too will be an adventure as I have much to learn about actually working with cryptomeria!

Large cryptomeria air layer – part 1

Over three years ago, I mentioned picking up a cryptomeria at Maruyama’s Bonsai Nursery, but had yet to follow up with a post. Here’s the tree.

Cryptomeria

Tall cryptomeria – about 48″

The tree was the left-over base from which a large air layer had been removed. Although there was little taper, much of the trunk was straight so I thought this could become a good project.

I’d long wanted a cryptomeria bonsai after watching a friend’s tree develop over many years. Although the tree is now in a different collection, it’s under the care of Michael Hagedorn and is looking great (see Michael’s post “Cryptomeria and Foemina juniper year two“).

As the base of the trunk was a bit wobbly, I spent a long time spinning the tree on a turntable trying to identify the lowest spot from which I could layer a straight section of trunk. I ended up selecting a point about a quarter of the way up.

The layer process was straightforward. Having practiced on younger trees (see “How to air layer cryptomeria for bonsai” and “Cryptomeria from air layer“) I was ready to cut into this much larger tree. I began by removing a large ring of bark. In hindsight, the ring didn’t need to be so large.

Next I affixed some plastic with aluminum wire.

I may have skipped root hormone as cryptomerias layer easily. After adding moss, I held moss and plastic in place with wire.

I completed this work in May of 2011. By fall, I saw lots of roots so I removed the moss and took a look.

This is where the fun started. Although there were plenty of roots, I wasn’t comfortable removing the layer so I built a temporary pot in which the roots could continue to grow. The pot comprised two nursery flats lined with plastic screen held together with aluminum wire. I assembled the pot in place and carefully spread out the roots.

I added a little bit of bonsai soil at a time, working it in between the roots as I went along.

When I was finished, I covered the soil with shredded sphagnum moss to retain extra moisture

The result was easily the strangest looking tree in the yard.

Japanese maple air layer – a check up

Posted in Bonsai Development by Jonas Dupuich on May 10, 2013

Last May I started an air layer on an old Japanese maple (see “Air layering a Japanese maple“). Curious if there was any root growth, I opened up the bag in February. There was callus, but no new roots.

Callus

Good callus, no roots

To stimulate the production of new roots, I opened up the callus and applied root hormone. I then replaced the moss and waited for spring.

The maple leafed out as it always does, but a few weeks ago I noticed that the leaves above the layer line began to turn pale. This is a good sign as discoloration is common when new roots start to develop.

To satisfy my curiosity, I opened up the bag and looked inside. A few new roots were just getting started.

I replaced the moss again and closed up the bag. I’ll watch the bag carefully this summer to make sure it doesn’t dry out and will see about adding soil around the moss if it starts to dry out too quickly. I’ll peek inside again this fall.
