Re: To chop or allow to grow

I have see the trunk die back so the I healed area in the second pic was actually me scraping away the dead area to see where it ended.as it’s in a weird area, I was thinking of carving a hollow there leading up to the top branch and retain the lower branch as well. The other option I thought about was to cut where the lower branch and then let grow to heal over. What would be a better option?
For the first pic what is not very clear is that the tree has died on one side of the trunk while the side that supports the active growth is alive. So not expecting it to cover over. So both these I think will end up as carved specimens. Never carved before; can I leave the carving to the point that I have developed the tree or do I have to do it now?
The last pick need a major shakeout I am looking to develop it as a single trunk which branches out at the top to two and so on so a major pruning is in order (when I get the time hopefully this weekend) will post when done on that one.This one has a good radial root structure so feel might be the best of the three eventually.

You can lave carving to whenever you get the tools and fortitude. The dead wood won't suddenly heal up or otherwise disappear. It may rot a little but that usually only gives a far more natural looking result IMHO.
If you are worried about the wood rotting away treat with a preservative a couple of times each year. Lime sulphur is the traditional wood preservative used in bonsai. Read up on how and what to expect before trying it. There is no danger to your tree if the dead parts do rot a bit or even a lot. The live parts usually resist the dead wood decay process. That's why we can have hollow trees in nature.

I can see the dead area in your recent photo. That tree is small so if you really wanted to you could heal over that dead area but it would take some years.
The 2 options - carve and keep both branches or cut and heal - are both viable. There's nothing in that tree that says one will be better than the other so it will come down to your preference.

Thanks for your reply. I will leave it to grow with the stump then and look to carve it out later in its life. Where in Melbourne can I find lime sulphur?

Any nursery or plant supply place will have lime sulphur. Even the green shed should have it. Lime sulphur is used as a dormant spray for fruit trees as it prevents fungal infection and kills some pests as well so it is readily available.

Nice effort!

agree with shibui that cutting back the nob and the surrounding tissue to get it to roll over as well
Same to be done to the new cut as well

In regards to lime sulphur, something like this:

can be found at pretty much any hardware/gardening store around Oz.

While I have left the first two trees to continue to grow and develop some thickness and branches, I am pretty happy with where the third one is in terms of trunk girth and taper or lack thereof...anyways decided that it had far too many long branches that didn’t quite give the little tree strong bones to develop from so went a bit hard on it. The end objective is to have single trunk splitting into two and so on and so forth...

The picture above is what I am thinking of using as the front. Another option is also provided below:

Appreciate any suggestions and feedback that will help me develop this tree which is about 20-30cms from the trunk base to the top.
It is currently just in a melamine “pot” which I repurposed from what was lying around and have provided more room for the roots to go crazy as I had done some decent root work on it.
I ended up cutting the lowest branch which was too thick and distracted from the flow from base to top. But I am now left with the thick bit which I will cut flush to the main trunk but need to find the cutters :-(

Any advice and suggestions
really appreciated.

Are apples/crab apples one of the species where it is advisable to leave a stub and allow the tree to compartmentalise before removing?

I think I prefer the second option which has the tallest part (apex) toward the front of the tree. having the apex going away looks odd and makes the tree look like it is falling backward.
I have cut apples flush without and problem but leaving a stub temporarily won't hurt either.

Got it from Bunnings. They only had the bigger bottle! Now to find a clear day to start experimenting with applying it.
