    I've thought about the left branch a lot. Most of the wood in the front is actually dead already, but I was a little worried about some instability in the root system if I remove it. However, the tree has grown so strongly on the right that I think the contribution from the small branch on the...

    I also reached out to @MACH5 for some design ideas. Sergio now offers a digital painting service and anyone who doesn't appreciate his design skills has been living under a rock. Here is the preferred design style he sent me. It may be hard to appreciate from my pictures at first glance, but...

    A quick update on the tree from some recent shots at different angles. You can see that it has successfully survived the very aggressive removal of a large tap root. There are several nice branches on the right. This year, I am just fertilizing and watering to try and produce as much root...

    Large JMaple Ground Layer Advice

    I was thinking I could just get a larger pot than the green one, carefully remove the green one and slide the new one around, then fill the sides with new soil. The current box is actually much wider than the one in the picture I uploaded.

    Large JMaple Ground Layer Advice

    It does make sense, although my goal is to be able to screw this onto a board in the near future. I might just go for a slip pot approach which would essentially do what you suggest but allow for even more root growth and then do a formal repot in the spring.

    Now that is definitely thinking outside the box....

    Large JMaple Ground Layer Advice

    Currently there is a pretty healthy mass of foliage, which I image draws a lot of water. Humidity is not a problem as our normal humidity is pretty high (91% this am). It is the heat that I worry about with temperatures routinely in the 90s. I do have it under a pergola plus 30% shade cloth...

    Great idea. I wasn't sure how I would fit a traditional saw under here.

    Large JMaple Ground Layer Advice

    Hi All, I've done a number of successful air layers over the last couple years, but never a large ground layer and I am looking for advice. This Japanese Maple is a larger field grown material with a base approximately 5" across. There were a number of very large scars from sacrifice branches...

    How do you make a tea from this? Is it just water that drains out of the bucket?

    Presumed recurrent fungal infection on Trident Maple

    We did a club zoom meeting today with Jonas Duipich and I showed him pictures and asked about this. He said it is not an uncommon problem and he has struggled with it. He had some trees sent to the lab for testing. It is a combination of soil fungus with pythium and then a leaf fungus...

    Presumed recurrent fungal infection on Trident Maple

    I have been much more diligent about my overwinter anti-fungal regimen. This year I used lime sulphur, oxiphos, and copper sulfate spread out over the course of winter (not all at once). Since budding out, I have been doing once monthly granular applications of systemic Cleary 3336. I have...

    New Bonsai Garden Display Progression Thread

    An early Summer photograph. I have 30% shade cloth over the pergola. I've also planted a bunch of ferns along the walkway. I drove an old railroad spike into one of the posts and hung some metal art which will continue to rust. The large wind bell also has a nice rusty patina. Finally, I...
