Japanese Black Pine #21 – August 2017 Update - Repotting

It's only been one year since this tree was repotted and I wanted to inspect the root growth after my feeding regime and the open mix that was used at last repot. It was becoming difficult to water due to the density of the roots and I'm aware repotting this soon may encourage more coarse growth than if it was left but my focus is still on the roots and ensuring this pine is as strong as it possibly can be.

Here's what I found after just one year - 

There was a lot of roots and they had just woken from dormancy so the timing was perfect. There was lots and lots of mycorrhiza too which always puts a smile on my dial.

I changed the pot as well.

And the end result. Now the plan is to work on the ramification and structure of the tree. The roots are just where I like them.


Japanese Black Pine #21 – April 2017 Update - Structural Wiring and Bud Selection

 

So this Japanese Black Pine has had plenty of time for recuperation and to develop a solid root structure. It's been well fed and left to just build its overall strength and vitality. There is a lot of mycorrhiza visible just below the soil surface so everything looks like it's heading in the right direction. I have been very keen to get into this one and do the initial structural wiring but I've held back...until now.

Here's the tree as it came of the bench.

There were 3 sacrifice branches that were allowed to run and increase vigour. These will be removed as I'm a little concerned that the tree is putting all it's energy into the sacrificial growth and not the remaining buds. 

The wound at the back of the trunk has been healing well and it was reactivated and covered with wound putty again. The snails had eaten the last lot!

So the first job was to prune unnecessary buds and branches and remove old needles and just balance the energy of the tree.

The trunk still impresses me and gives me hope.

Warts and all, this is the initial rough wiring of this bonsai. Keep in mind, this is not show wiring but 'setting the bones' for the future. 

I'm really pleased with how it is progressing and even though it has been a long, patient journey, that's what it is, a journey. 

 


Japanese Black Pine #21 – August 2016 Update - Repotting and Angle Change

Well it's been 3 years since I first acquired this tree and repotted it with the only focus being on the strength of the roots and overall health of the tree. Sometimes you just cannot rush; patience really is a virtue.

Initially the tree was removed from the pot. The roots had grown so thick and dense that it took quite some effort to free the tree. The akadama that was in the mix had broken down as it does, and a repot it due.

The roots that had developed were very pleasing to see.

The roots were pruned, and the nebari corrected in a few minor places then the tree was secured back into the same pot. I like this pot as it's an old one that was purchased on a trip to Osaka and the style suits this tree.

The mix was worked into the pot and then levelled.

Sphagnum moss was chopped and put on top.

The lower trunk is one of the most pleasing features of this tree. The age is really starting to show and makes the work that goes into this bonsai all worth it.

So here's where the tree was and where it is now -

The tree was tilted to the left to enhance the first movement on the lower trunk and to also make the second bend less horizontal. It also brings the apex back over the centre of the nebari. The tree was also rotated slightly clockwise in the pot so the apex is now leaning forward a little more.

You can see from these photos that the tree is looking far more vigorous now and a nicer shade of green (as opposed to yellow). The tree still hasn't been wired and depending on the spring growth, this may be on the cards for summer when the tree is decandled. Or, it might just wait until autumn next year. No rush. That's why this is a project and not just a styling.

 


Japanese Black Pine #21 – August 2015 Update

So here's where the tree was -

It was well fed and the root mass feels very solid now so leaving the tree alone has done it wonders in regaining its vigour.

Here's what it looks like now (the apex has a long, long, long way to go) -

With Spring upon us, the candles have just started to move and I'm looking forward to a good result with decandling in Summer. You can see from the above pic that the fertilisers bags were left on over winter. I do this with the weaker trees if they are not being repotted. I did intend to repot this tree but that can wait another year. Changing the angle to improve the appearance can come later. For now it all about the growth!


Japanese Black Pine #21 - April 2015 Update

So, this tree was pretty weak when I first acquired it. Here is a refresher -

IMG_5709

That was in September 2013. It was repotted into an open mix, consistently fed really well with organic fertiliser, kept in full sun and allowed to grow. Only the apex was decandled in summer and basically it was left alone until April 2015.

During this time the roots have grown and the surface had become very compacted so it was time to open it up a little and add a new surface layer.

While the tree was in the workshop I decided to do some work on the scar around the back of the trunk that is from a sacrifice branch.

So the inner rim of the cambium layer that has formed was scratched a little to reactivate the healing process. Then the wound is covered with cut paste. We'll see what has happened in spring.

It's autumn at the moment so I also went through the tree and selected buds and did a small amount of needle plucking. There were 2 year old needles that had started to drop and I wanted to ensure good air flow and sunlight into the inner areas.

 

Here's how it looks now -

It's much healthier and the overall vigour of the tree has significantly improved as well as the colour of the needles. It's been given another dose of fertiliser too before winter comes along.

While I was working on the tree I found the harsh angle of the trunk to be a little disturbing so I'm going to rotate the tree clockwise when I repot in Spring.

This rotation reveals more of the trunk line, creates more interest and displays the nebari much better.

So for now, it's more sun, more wind and fertilising until winter.
