Hard Pruning a Schefflera

When someone at a bonsai workshop advises me to chop trees back to leafless stumps, I'm often reluctant to do it. Although I've had some success with trunk chops, most of the time I'd rather cut trees back to the lowest growth, wait for back budding, then cut back further. Progress is a little slower that way, but I prefer to err on the side of caution.

With some species that approach doesn't work though. When I prune Scheffleras they tend to grow back from the point at which they were cut, not lower down where I want new branches.

So when I decided that this little Schefflera needed pruning, drastic measures were called for.

November 2019 -  before pruning

Some of the newer members of my club were horrified when I told them my plans, but I knew what had to be done. A few quick cuts later I was left with this.

November 2019 - after pruning

Scheffleras are slow growers and now, four weeks later, there are only a few tiny buds starting to put in an appearance on the branches. I know that my little tree is doing okay, but looking at it still makes me nervous.

At the time it was chopped I discussed my plans for its after-care with another member of my club. I said I intended to return it to its home in my greenhouse. He felt it should go outside.

At the time his idea seemed a viable option as the weather was extremely dry, so I felt a bit foolish when I said I wanted to protect it from the possibility of excess rain. But I feel vindicated now because it's been raining almost continuously for nearly five days. Slow persistent rain which is showing no sign of abating. Grey skies have become the norm and I've almost forgotten what the sun looks like! That's not normal weather where I live, but it happens every now and then.

I've seen what damage that kind of weather can do to a tree in this state.

Years ago I defoliated a similar Schefflera. That was back in the days when I still tried to grow some of my trees indoors. Keeping it inside shouldn't have been a problem. Scheffleras are very tolerant.  I kept my big one in a very dark room for years before I realised the error of my ways and moved it outside. My problem was that I lost patience. When it was progressing too slowly on a sunny windowsill, I decided to move it outside.

As luck would have it, a few days later we were hit by the kind of weather we're experiencing now. Too much water for a tree without leaves! In a few days it was dead.

Had I left this one exposed to the elements, it would probably have died too.

How to Kill a Juniper

Browsing through the Reddit bonsai group there are always a lot of posts from newbies with their first tree, and that tree is often a Juniper. Sadly many are led to believe that it's okay to keep their Juniper indoors. The truth is that's the easiest way to kill it. The bad news is that Junipers stay green for months while they're dying, and by the time the owner realises their tree is sick, it's usually already long dead.

I was lucky. I've never made that particular mistake. But that's not to say I've never killed a Juniper.

I've already written a few posts about the Juniper Mint Julep I bought as a candidate for Reddit's nursery stock contest in March 2018.

As purchased - March 2018

Having seen many people on Reddit advising first time Juniper growers not to do too much work at once, I tried to be gentle with my tree and though I removed a lot of the top, I left a couple of unwanted low branches to avoid shocking the tree too much.

April 2018

It made it through the Southern hemisphere winter without any trouble.

My big mistake was taking it to a club meeting in September 2018. I didn't even plan for it to go on the table for critique, just to enquire from an expert whether it was safe to remove those low branches. Unfortunately some of the members had other ideas, and I came home with this:

September 2018

I was really disappointed with this new styling and felt it was no longer "my" tree. And I was extremely concerned about its survival. The suggestion that I repot it immediately sounded like a bad idea, and I decided against it.

Perhaps at that stage it still stood a chance of surviving, though it would have been a long time before it grew branches that I would  have been happy to work with. Unfortunately, when discussing the tree with another experienced grower a few weeks later, I was told it was okay to repot it, so I did. The root pruning involved was the last straw, and by December 2018 it had lost all its foliage, though I found signs of hope in the form of one tiny green bud growing from the section that was intended to be used as dead wood.

Signs of hope - December 2018

And my hopes were finally dashed when that bud died a few weeks ago.

If I ever buy another Juniper (unlikely), I'll definitely take my advice from Reddit and stick to the principle of one insult per season. Perhaps they can survive more, but there are bound to be problems along the way.

That was certainly the case with a Juniper I worked on when I attended a beginner's course back in 2007. The tree was pruned, wired and planted in a bonsai pot, all over the period of two days. It survived, but the top died and a makeover was required within months. It's been restyled a few times since then, but to this day I'm not happy with that tree and I'm determined to find it a new home one day. If I can get a little money for it, I'll probably spend it on another ficus!

The Second Ficus

Yesterday's post was all about the first of my two neglected ficuses, a tree which had benefited greatly from the development of a vigorous and totally unplanned sacrifice branch.

At the time I had not yet done anything to its sibling aside from removing a few dead branches. I've just finished working on that one - it received much harsher treatment than yesterday's tree because the trunk was long and straight with very little taper.

Ficus Natalensis - March 2019

I started by removing the top section, which left potential for something approximating a formal upright tree:


I contemplated stopping there. However I'm trying to focus on short fat trees rather than tall skinny ones, so I knew I wouldn't be happy with that in the long term.

In the end I stuck to my original plan and cut to the lowest branch, leaving what is currently a very ugly tree.

March 2019 - after the chop

No point in wiring that branch because I don't plan to use it as a leader. It's just a sacrifice branch which will be removed along with approximately half the trunk once I get growth where I really want it.

Both trees - March 2019

I can't wait to see what these trees look like a year from now.

The Benefit of Neglect

I hate to admit that the last time I worked on my two neglected ficuses was when I repotted them in November 2015. Because of time constraints only one ever made it into my previous blog post and once again that's the only one I've had time to work on so far. Coincidentally, for the moment it's the better tree.

In November 2015 that tree looked like this:

Ficus Natalensis - November 2015

A few sharp bends and hardly any taper!

Although my neglect means that the trees are no closer to being bonsai than they were three years ago, the move to bigger pots has allowed them to grow big and tall and their trunks have fattened up considerably. Unfortunately the top growth has blocked light from the lower part of the trees and as a result, both have lost some lower branches. The tree above also developed a massive low branch which grew upwards, reaching a height  twice that of the intended apex.

Same tree - March 2019

Under the circumstances I found myself having to treat it as nursery stock when I took it to a workshop on Saturday afternoon.

First I had to get both trees out of the greenhouse though, and that proved to be quite a mission as once again one had sent a root into the other one's pot and both had also sent roots through the slats of the shelf they were living on. To complicated matters further, the neighbouring orchid (a gift which I tend to ignore) had sent roots into both pots. That meant there were quite a lot of roots that had to be cut before I could move the trees.

Once at the workshop the first step was to remove that huge branch.

After removing the huge branch

The tree was already looking better but it was rather top heavy, with a leader growing in the wrong direction. The club member I was working with recommended I cut back to a new leader, advice I was happy to follow, as I'd already said in 2015 that "At a later stage I might reduce the height further".

March 2019 - after pruning

As it's still in the same pot, the change in the thickness of the trunk is pretty obvious.

I've left all the aerial roots for now as we're headed into winter. I'll decide whether to keep any of them when I repot the tree in spring - as long as I don't forget!!

As for the second tree, it looked like this when I removed it from the greenhouse:

Second tree - March 2019

I've removed a few dead branches so far and plan to cut it back to the lowest living branch, then wait for back budding before cutting in to a more suitable height. I'd like to make a short, fat little tree from this one.

Starting a Pyracantha Bonsai From Nursery Stock

A few days ago I found this Pyracantha at the nursery section of a nearby hardware store.

Pyracantha as purchased - January 2019

I shouldn't really be buying more trees, but my only Pyracantha died about a year ago, so I couldn't resist the temptation to replace it.

I was pretty sure I knew what I needed to do with this one, but I took it to a workshop on Saturday in the vain hope that I'd be told my plans were too drastic.

No such luck. It was never going to work as a twin trunk because one trunk had lots of movement while the other was dead straight.

Close-up showing two unmatched trunks

The straight one had to go. Two cuts and I was done.

January 2019 - after pruning

I was really sad to see all the berries go into the trash can, but sometimes the art of bonsai requires sacrifices.

Now I'll let the tree grow for a while before deciding on the next step. Perhaps in time I'll cut it even shorter.

Photo updates will appear on this page.

My First Carving Attempt

When I bought my crab apple a few years ago it was about seven foot tall with no low branches, so it's taken a bit of effort to get it to where it is now.

January 2019 - before pruning

A lot of the tree had to be discarded at the time because repotting was a matter of urgency when I bought it, but there was enough left to allow me to do an air layer before I started developing this, the parent tree.

I'm ashamed to admit that since the air layer was removed, however, I've largely ignored both trees. That created a problem with this one because the top branch on the left was thicker than the lower branches and apex. I had to change something.

Two options presented themselves :

  1. change the planting angle and turn the thick branch into the new leader
  2. remove that branch
I opted for the latter.

January 2019 - after pruning

After the branch was removed I was left with an ugly bulge where it had been.

In the past I'd have asked for help with that bulge, but I recently bought a Dremel carving tool, so I decided this was the perfect opportunity to try it out.

Janurary 2019 -  after carving

Not a perfect job by any means, but for a first attempt, I'm reasonably happy. When I've got a bit more carving experience, I can still come back and improve on it.

For now I want the two side branches to thicken a little more before I shorten them, and the new leader and back branch need a lot of fattening up.

A Pruning Adventure - an Update on my Reddit Contest Tree

I hate to confess that I've totally neglected my first lonicera, styled in November 2017, then changed a bit after receiving some bad advice. It's now totally overgrown and I need to start all over again.

After seeing how quickly such small trees can get out of control, I'm determined not to let the same thing happen to the lonicera I used for the Reddit nursery stock contest this year, so a few days ago I decided it was time to give it a haircut.

Lonicera - December 2018, before pruning

That's when the fun began.

While trimming some of the top foliage I suddenly became aware of a praying mantis hiding in the branches.


I immediately stopped what I was doing before he came to any harm.

After taking a few photos, it was time to get him out of the tree. Surprisingly I had no difficulty persuading him to climb onto my hand, and was even able to get a few more shots.


I then moved him to the safety of a tree I wasn't planning to work on.

Finally it was time to get back to my lonicera. After a little more work it looks like this:

Lonicera - December 2018, after pruning

That long dangling branch is a new one about two thirds of the way up the trunk which will fill a gap nicely. It needs to thicken up a bit before I prune it. I don't think that will take too long though, so I need to keep a close watch on it.

I'm not happy with the lowest branch on the left yet. Hopefully I'll get some back budding so that I can direct it in the direction I want it to grow. And I'm still considering shortening the tree a little more.

Now that the contest is over, however, I don't need to keep it looking tidy, so I can take my time making my decisions.

Seven Months in the Creation of a Lonicera Bonsai - my Reddit Competition Tree

When I entered Reddit's Nursery Stock Contest back in autumn, I knew that it was going to be a lot more challenging for me than it was for my Northern hemisphere friends because I would have very little of the growing season to work with.

Under the circumstances I'd probably have been better off working with a Juniper than the Lonicera which became my competition tree, and I did buy one. The wrong one! I shouldn't have bought that tree for a number of reasons:

  1. I don't enjoy working with Junipers
  2. I knew nothing about Juniper Mint Julep until after I'd bought the tree, when a little research led me to believe that the species isn't regarded as good bonsai material
  3. The tree I bought was far bigger than the material I like to work with.
The Lonicera I finally entered in the competition had none of those problems. It has tiny leaves which are well suited to bonsai - even mame trees. But in the summer months it's essential to prune regularly or a little one like mine will soon grow totally out of control.

I bought my tree on a cold rainy day in April. A day so miserable I had the entire nursery to myself. Even the staff were reluctant to offer any assistance.

I must have been quite a sight, bent down close to the ground to examine the trees using one hand while I clung onto my umbrella with the other. I stayed well away from the big trees that day.

My purchase looked like this:

Lonicera as purchased, 6 April 2018

I decided to take things slowly, rather than cutting off anything I would regret, so after an initial pruning it looked like this:

First pruning, 6 April

I tied a couple of loose wires around trunks I was considering removing.

A few days later I was feeling more daring and reduced the tree to a very basic frame.

Second pruning, 11 April

Unfortunately some of the branches were still longer than I'd have liked them to be, but I didn't want to kill them by leaving them devoid of foliage.

By early May the tree was pushing out a little new growth, giving me hope that I'd be able to improve on the styling over the next few months.

New growth, 3 May

And by the middle of June it was really overgrown:

Overgrown, 19 June

Time to tidy up:

19 June

I still wasn't getting the back budding I really wanted though, so that left branch in particular was way too long and bare.

July was a slow month with only minimal signs of new growth, so I did nothing.

21 July

Then in August I finally felt there was enough growth lower down to let me shorten some of the branches.

After heavy pruning  - 17 August

Spring growth was pretty good:

21 September

With the benefit of hindsight, maybe I shouldn't have removed so much before submitting my final photo for the contest.

Final contest photo - 21 September

Still, I'm not too unhappy with the outcome given the constraints I was working under.

The contest is over, but the journey continues.

The little guy is growing well.

6 November

I was far less aggressive with my latest pruning because my emphasis has changed. Now I need to fatten up the branches I plan to keep.

6 November - after pruning

That shouldn't take long though. Not on such a tiny tree. As it stands today, the little guy is a mere 11cm tall. And in a few months time I may reduce the height a little further.

Starting a Large Portulacaria Bonsai from Nursery Stock

I never meant to buy anything.

When I stopped at the nursery about 10 days ago, I was just trying to burn a little time before meeting a friend at a nearby restaurant. I'm supposed to be cutting down on the number of trees in my collection, not adding more.

Everything started off well. The trident maples had decent bases, but they were about 10 feet tall with no low branches, so they were easy to ignore. And the small Portulacarias weren't the least bit tempting. I've already got a few and I tend to neglect them. So much so that I nearly lost one to root rot last year. I've reached the stage where I try not to buy anything unless it's a little bit special, like the variegated Portulacaria I bought in July.

But when I passed the big Portulacarias in another section of the nursery, everything changed. I'm not aware of ever seeing them that size before - well not unless they were growing in the ground anyway. Even so I nearly passed them by because the bags of soil they were planted in were so big that I felt sure I wouldn't be able to lift them. But I tried lifting one and was surprised to find that it was a lot lighter than it looked.

I couldn't buy it though. Not that day. I couldn't leave it standing in the car, visible for all the world to see, while I was at the restaurant.

It was three days before I was able to return. Luckily my chosen plant was still there because the others had much thinner trunks. Well all except one, and it turned out that I couldn't lift that one.

And so I came home with this huge plant which, in its bag, reached to just below my chin.

October 2018 - as purchased

I couldn't even contemplate putting it into a training pot until I'd removed all the excess growth.

October 2018 - after first rough pruning

At this stage all the branches on the left were in a straight line and I knew most of them would have to go, but I decided to leave my final selection until the tree was in a pot, planted at the correct height. A wise decision because, by the time the highest roots were exposed, the tree appeared a couple of inches taller.

October 2018 - still waiting for its final cut

I didn't discover that until a few days later though. Given its size I decided to get some help with the root work at my club's meeting.

In addition to adding height to the tree, removing the top layer of soil also exposed a couple of branches with their own roots, giving me two extra (much smaller) plants for my money.

October 2018 - two branches with their own roots

Once the tree was safely potted, it was time for the final branch selection. I was happy to find that several club members agreed with my decision to reduce the height a little further. Once I'd cut back to my chosen leader, the right branch was perfectly positioned on the bend. After removing the handlebars and the low branch coming straight to the front, I was left with just two branches. For now.

October 2018 - after final pruning

Who knows what options may present themselves when new growth appears?

It's unfortunate that the higher branch is the thicker of the two, but hopefully if I let the thinner one grow and keep the thicker one short, it won't take too long to correct that fault.

One last photo, just to show the size of the tree:

October 2018 - soda can for size

In addition to the two branches with roots, I've kept a lot of cuttings. If they all root, I'll have a not-so-small forest of Portulacarias of various sizes growing in my bonsai area. Maybe in a year or so I'll be able to sell some of them and recover the cost of the parent tree.

Finding the Bonsai Inside the Tree

At last Saturday's BRAT meeting we saw two talented artists at work. Both are recent winners of the national new talent competition.

As is the case with the new talent competition, the artists were supplied with material they'd never seen before. This time, however, they were working with vastly superior material - two Juniper Procumbens Nana "shrubs" which had been grown specifically for use as bonsai. Yet to the untrained eye they might have passed as simple nursery stock.

Here they are at the beginning of the demonstration:


Tree 1


Shaundre's tree

Shaundre Craukamp is a member of Eastern Bonsai Society (my club). He won the national competition in 2015.






Attracting young people to the art of bonsai is a huge concern. Most of my club's members are well over forty. Shaundre represents the future of my club. He's still at school. We desperately need to attract more members of his age.

Tree 2


Stefann's tree

Stefann Pretorius, a member of Suikerbos Bonsai Kai, won the national competition in 2016. Here he is assisted by Hannes Fritz, an experienced bonsai artist who represented South Africa when he did his own demonstration at the 8th World Bonsai Convention in Japan in 2017.
