acacia nigrescens winter image
« on: July 18, 2014, 07:51 AM »
Hi guys,

Some more bad pics haha. Just wired out my twin trin knob thorn.

Bit unconventional type of style for this tree. Though in the wild tha have very long straight trunks and form a column shaped silhouette, so ive decided to have fun with this one

Kind regards
Herman

Ps will go take some better pics and post them later

How hard can you cut them back when dormant?

Hi Owen,

you can cut them back to the first node on a branch just as the buds starts to swell. This usually causes heavy back budding and even double budding from the same node.

I would like to see more of this tree, hopefully upright this time.
We seem to be seeing a lot of this new style of tree, instead of informal upright it's "informal sideways" that is all the rage :D :D

Hehehe, the new thing seems to be upside down growing trees...beats me how the people keep the growing medium inside the pots  ;D

some history on this tree...

in 1998 my big brother planted a whole lot of seed, and in spring 2004 my brother sold most of them to a commercial nursery, as the owner wanted to start marketing thorn tree bonsai, only the smaller weaker trees stayed behind. In 2005 it was given to me as a gift. it had a 3 inch trunk and stood about 2-3 feet high. It was a no brainer that i would train it into a bushveld thorn tree style; but in it's second winter with me it got left outside and was hit by black frost, bad judgement on my side...the tree died back to soil level. I checked it in spring for signs of life and saw it was pushing two buds on either side of the trunk just above soil level. I cut back the dead trunk to just above the new buds and left it to grow for 2 years before starting to work on it. after a repot in 2012 it started sulking and didn't put much growth on at all until december last year when it suddenly perked up and pushed a lot of new growth. so I worked it this winter.

I've taken some new pics of 4 sides and a shot from above. pics to follow in the next post

kind regards
Herman

Herman, another interesting one. You don't want this to end up looking like a pine. The question is how do you get it to transition to a number of smaller vertically growing branches to build an apex, think small broom. Think as you look at the branching, some of the larger upper branches could be shortened and the angles adjusted to make them intermediate the tapered, this would allpw you to visualize the transition from the oldest, heaviest and sagging lower branches up through the intermediate portion of the tree to the youngest and most vertical portion of the tree, the top. Very nice, very well developed, and nicely wired.

Hello Mr Kirby,

I agree that some of the top branches are very heavy and I plan to cut back hard on them when the tree starts budding in late September early October. This will give me a whole lot of branches to create the apex with. Small broom on top for an apex will look very natural and I'm going to follow your advice. Another shortcoming of this tree is that the lower branches are thin compared to the top ones...this happened in the last growing season when the tree finally got into second gear after it sulked for a long time due to a weak root system. So the benefit will be two fold when I cut it hard in the apex region.

thank you for the compliments :)

Best regards
Herman

I'm sorry but it just don't work for me. No offence but a Knob thorns strength starts at the bottom with its strong spreading branches tapering upwards. I did see some very old knobbies in Botswana that had long bare trunks, but their upper branches are always reaching for the sky. Those pulled down side branches just does not work on a state like tree as a Knob thorn...... :(
