Just another update on the progress of the Acacia Karoo.

The tree is incredibly healthy and there is loads of new growth.  I cut back some more and did some wiring on the crown area so that the 2 crown areas were separated.  I am still undecided if I should keep both crown areas of if I should remove one, but for right now they will stay as it is assisting with the growth.

Pic 3.  Bending of the upper crown branch.

Another update.

In just over a month of growth, the acacia needed to be cut again.  I am starting to think that this tree is half weed as it does not stop growing.

I went away on holiday end December and January to Italy and when I came back, the Acacia seemed to confirm to me that it is actually half weed.

It had gone totally wild and grown shoots everywhere.  It was in serious need of a severe cut back.

Pic 1,2 - 17 Jan 2016 - Wild and in need of a trim

I have always been breaking off the new shoots that have started to grow on the trunk.  As soon as they would appear, I would break them off.  The reason for this was that I was worried that it would start to create bumps on the trunk where it grows.  I noticed that after all this rapid growth, the shoots along the trunk thicken up without any noticeable swelling at the base of the growth. For this reason I am now leaving the new growth along the trunk for longer as it will definitely assist with the thickening up of the trunk.

After taking all the pics for my bonsai page, it was time to trim and get rid of all the new growth.

So in the space of exactly one year to the day from when I received it and planted it into a large container, this tree has made a huge change in appearance.

Pic 1 - 17 January 2015

Pic 2 - 17 January 2016

I think over the next few months / years it will undergo even more changes (for the better I hope)

One option that was suggested to me is V notching for the lowest part of the trunk.  I will definitely look into that in Spring 16 (September) and I also want to put some more movement in some parts of the trunk.  But for now it has grown like mad again over the last month and in need of another haircut.

Have you considered, based on the last pic, bending the part that sticks out to the right down about 90° (CW)?

Hi Bwaynef

Are you talking about the area circled in yellow? (Pic 1), if not please advise?

Not too sure what you meant about CW?

Right now my thoughts have only really been on changing the angle of the lowest part of the trunk (Circled in Red) Pic 2

My thoughts have been to v notch that area first (red circle) and once that has been done consider the rest of the trunk for more movement?  Also not even too sure about the direction to V notch it in as to what will add the best impact to overall view.

Would love to hear your thoughts on moving forward with this.

Thanks
Doz

That's the area.  CW = Clock-wise.

Not exactly.  Look at the picture posted above my initial (today) response.  The picture you put a yellow circle on.  Move the part in the yellow circle down 90-ish °.

Leave it as is, or plant it in more of a (semi-?) cascde angle.  ...or ignore it completely.  Its just the first idea that I had when I saw the latest post.

Okay.

So lets see if my virts do your thoughts justice.

I did a 90 degree twist and then some.

I can immediately see a totally different view to this.

Thoughts?

That's the rough idea.  I'd tighten things up ...and after seeing the virt, I'd think hard about leaning it to the right and pondering its future as a cascade.  (I have no idea how acacia grows, so that may not be feasible.)

Like I said earlier, I am sure this acacia is half weed.  It grows like mad.  I am sure it would be feasible to be able to grow it in a cascade.  I am starting to see your idea and I do like it.

The biggest problem now is the straight part of trunk close to the base.  That piece has hardened off and I will have to look at Vnotching it.  With the way that it is growing I am sure that it will work and heal quickly but I think will be best be left for Spring (Sept 2016)

I do have a bonsai meeting this weekend so I am thinking of taking it along to rewire it and put more movement into the trunk.  I wired it last year in January and left it to set over the winter months and it came out okay so I think wiring it now will work.

I was looking through the net and found 2 cascades that impressed me. 

Pic 1 is by Tony Tickle.
Pic 2 was found on the Bonsai Bark web page but I cannot say who's bonsai it is.

I live in Baja Sur,California(Mexico,that is).There are about 50 species of the Acacia genus growing on this peninsula.I collected a seedling and it is doing fine.The real problem is identifying it.At any rate,is what you call"Sweet Thorn"-Acacia farnesiana by any chance?

Hi Geo


The Sweet Thorn is know as Acacia Karroo.  According to Wikipedia it has not been introduced into the States. But after looking at the Acacia Farnesiana they do look very much alike and Acacia Farnesiana does occur in South Africa

https://en.wikipedia.org/wiki/Acacia_karroo
https://en.wikipedia.org/wiki/Vachellia_farnesiana

But the species name has now changed to Vachellia karroo as the Species Acacia has been taken for another species of plant in Australia.

I must dissent on 2 comments.

"less soil".
Normally to develop trunk size lots of growing room is needed as in the ground and not a small pot and little soil.

"break those off".
One normally wants to grow sacrifice branches just above where trunk size is desired.  Is this not true?  Should not be way up at terminus or all trunk will have none or little taper.
