My Air Layering Blunder - 3 months later

In January I wrote about the bad mistake I made removing the air layer from a Ficus Ingens. I was quite concerned about the new tree's ability to survive after I accidentally removed most of the roots. Happily there was just enough root left to keep it alive and it's now full of foliage.

It's never going to be a beauty with its two leaders, but in time I'll probably do another air layer to remove the leader growing to the right. Do I need another tree? No, but I can always sell off some of the excess when I decide which of my trees I like best.

The news isn't as good regarding the little stub which had most of the roots. It was looking promising in February, when I took this photo.

Unfortunately that little bud at the base never developed into anything. Perhaps something else will still develop but I fear it may be suffering from root rot given the fact that I planted both in one pot and I've had to water according to the requirements of the tree which has foliage.

Of course the important part was always the parent tree. After removing the air layer all that was left was a thin leader with a few leaves.

I'm reasonably happy with it's growth over the last three months.

Sadly there are no signs of new branches lower down, but hopefully when I prune the tree it will stimulate new growth where I want it. With winter rapidly approaching, however, I have no plans to prune it any time soon.

A Tree with Dramatic Curves - 19 Months Later

Shortly after I started my blog I wrote about a little Acacia Burkei which started life as mallsai. Over a period of four years its trunkline had been changed dramatically, but it had little branching.

Some of my readers were very critical of the lack of branches and with the benefit of hindsight I probably did remove too many. Regardless, what's done is done, and I had no choice but to move forward with what was left.

September 2015

Over the last 19 months I've largely allowed this tree to do its own thing, letting the branches grow long, resulting in some significant thickening to the trunk.

March 2017 - before pruning

When I have pruned however, I've cut back hard because this tree has nasty thorns and in the limited space I have to keep it, it tends to get caught up in my other trees. My March pruning was particularly dramatic.

March 2017 - after pruning

I hadn't planned to prune it again before winter, but its growth over the past month was strong, and some of the upward growth was unnecessary.

April 2017 - before trim

While I was trying to organise my greenhouse ahead of winter, I decided to give it one more minor trim.

Here's a 360° view:

Ideally I'd like one or two more branches between the first and second branch.

After the March pruning the tree put out one new branch here:

Unwanted new growth

Unfortunately it was in an unsuitable position, so I was forced to remove it. However it gives me hope that a better option will present itself next summer.

What kind of worm is this?

When I finished watering my trees a little while ago I noticed a worm crawling along the rim of one of my pots. He was long and thin and at first glance I assumed he was an earthworm.

Then I realised that what appeared to be a large piece of soil at one end was in fact his head.

I wanted a clearer shot but he started moving into a position where his head was hidden, so I moved him onto a brick where he was more visible. The lighter background showed off his stripes a lot better too.

Aside from his strange appearance  something I found odd was that his length seemed to be variable. When I first noticed him he was fairly short, then, while I fetched my camera, he stretched himself out along the pot. After I moved him onto the brick he contracted again.

I have no idea whether he could do harm to my trees so I'm hoping somebody will be able to identify him for me.

I'll update this post if and when I get more information about him.

Ending Summer on a Positive Note

When I took my Schotia Brachypetala to my bonsai club for help with its initial trunk chop back in 2012 one of the senior members told me it was a slow grower and that I should plant it in the ground. As I was happy with the thickness of the trunk, I chose not to follow his advice. Based on how it has developed since then, I have no regrets.

I don't think it's so much a case of this tree growing slowly as that it needs a push every now and then to get it going. It certainly responds well every time I prune it. So perhaps it was a mistake to leave it to do its own thing for most of this summer.

At the beginning of March I decided it was time to rewire it as the old wires were starting to bite.

March 2017 - before pruning

While I was at it, I decided to give it a quick haircut. Mostly that just consisted of reducing the groups of compound leaves to pairs, but I think I pruned one branch at the time. Despite the fact that I kept the work to a minimum it ended up looking quite naked.

March 2017 - after pruning

Not for long though. Once more the haircut stimulated a lot of new growth, and a mere 17 days later I was happy to see lots of new buds developing in the large gap between the top branch and the apex.

New buds - March 2017

Two weeks later everything has filled in nicely apart from the lowest branch on the left which has suffered a little die-back.

April 2017

I suspect that branch may not be getting enough light, so perhaps I need to turn that side towards the sun.

With winter approaching I won't be working on this tree any more for a while. When spring comes around however, it will be time for a repot. The only surface root it has at the moment is badly positioned and will probably have to go, so I really hope I can find some better roots hidden below the soil.
