A Huge Juniper Transformed

Last Saturday I decided to attend a meeting at Midway Bonsai Society after hearing that a young member of Eastern Bonsai Society (EBS)  - the club I've been a member of for 12 years - would be doing a demonstration on a huge juniper.

Shaundre Craukamp may only be 19, but he already has a lot of bonsai experience, having joined his first club at the age of 10. After that club closed, he moved to EBS when he was 14. A year later he won the EBS and regional new talent competitions. Later that year he went on to win the national competition, becoming the youngest South African to do so.

The trees used for those competitions were nursery stock- Juniper Procumbens Nana, a little smaller than the one he's seen working on in an earlier post (he's the guy in black). Unlike the one in that post, however, competition trees have had no previous styling.

The tree he worked on this time was a collected tree - Juniper Chinensis - belonging to Jonathan Cain, a member of Midway.


Shaundre started by doing a little carving on some of the dead wood at the bottom. (There was far too much to be done in one session.)


He chose to do the carving by hand.


Then he moved on to the apex.


As everything up there was long and straight, and growing away from the trunk, a lot of bending was required - too much to be done at once without putting excessive strain on the tree, but enough to show the direction in which the tree will be developed.

First he split the area he wanted to bend, then he applied tape to prevent the branch breaking when he bent it.


After wiring the branch and adding some guy wires, he was able to pull it down in the direction he wants it to grow. I believe it will be brought closer to the trunk when it's had time to heal.


This was already a big improvement, but the branch coming up from the bend looked out of place, so he removed it, leaving a stub which will be used as a jin.


He then bent one of the lower branches up to create a new apex.


He marked a few areas that will need carving, including the marked branch, which is currently far too long and thick.


After all the small branches had been wired (with help from Jonathan and his wife Denise) and re-positioned the tree looked like this.


Shaundre will be paying Midway another visit next spring to do further work on this tree.

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.

Positive Results from a Trunk Chop

When I did my most recent air layer on a member of my Ficus Ingens family, I was hoping it would stimulate new growth lower down the trunk. As long as the air layer was attached to the parent tree, however, that never happened.

That's why, despite knowing that Ficus Ingens are tough trees, when I separated them in February I was a bit concerned about the survival of the parent tree which had been reduced to a bare stump. I ended my previous post posing the question :
"After it's stubborn refusal to produce any low branches, will this finally shock it into cooperating, or will it kill the tree?"
 Happily it did the former. The stump is alive and well, with lots of new branches all along the trunk:


In fact in several places the growth pattern of this species led to multiple branches sprouting from one spot.


I had to thin those out or they would have caused ugly bulges on the trunk as they thickened.


After a quick tidy up, the tree looks like this:


There are new buds sprouting near the top of the tree, so I should be able to keep it to its current height - if I choose to do so.

The lowest branch is still there. As the second photo was taken from the opposite side, it's hiding behind the trunk. I'm not making any styling decisions now, but once I see how the tree develops I may remove that branch.

A full progression as well as future updates for this tree can be found here.

The new tree I propagated from the top is doing well too.


It has a couple of new branches along the straight part of the trunk and there are already a few roots growing out of holes in the pond basket.


Pretty good for six weeks' growth!

The Art of Growing Miniature Bonsai

At their most recent meeting one of my bonsai clubs (I now belong to two) had a fascinating speaker, Hennie Reyneke, who is well known for his mame trees.

Hennie holding a little Ficus Burtt-Davyi

I've seen his trees before and was delighted to get the opportunity to see how he creates his little masterpieces.

Of course, as is the case with bigger trees, creating good mame takes time, but seeing tiny cuttings transformed into the skeleton on which future bonsai will be built was really inspiring and made me feel a little bit guilty about some of the cuttings I've thrown away lately. I do however still have a lot of small rooted cuttings that I can play with and having already started trying to downsize some of my own trees, I feel certain that this is the right way for me to go.

Here is a close up of Hennie pruning one tiny tree:



Another being wired:


And the same tree after a little pruning:



As with all trees, it is important that everything is in proportion for miniatures, so you should choose species with leaves which are able to reduce well. Flowers and fruit must be naturally small as their size cannot be reduced. Big flowers and fruit on a tiny tree will look wrong!

Some of the species that Hennie recommended for miniatures are Maples, Celtis, Ficus, Cotoneaster, Pyracantha, Buxus and Lonicera, as well as conifers like Juniper Procumbens Nana.

A little literati

If you've got the patience to do so, growing from seed is a good way to grow mame bonsai because you can create taper and balance without the scarring caused by heavy cuts. Hennie also mentioned that fig varieties develop a thick buttress base if grown from seed. I have no immediate plans for trying that though as I've managed to grow ficuses with nice bases from cuttings, root cuttings and air layers. I'm really happy with the base of the Ficus Natalensis in the last photo in this post. That little tree was grown from a root cutting.

Miniature bonsai can of course also be created from small collected trees or nursery stock.

It is important to prune your little trees regularly to keep them in shape (something I'm often guilty of forgetting) and they should be repotted once a year, removing heavy roots to encourage the development of a fine root system.

One of the most difficult aspects of caring for miniatures is seeing that they are watered correctly. A good way to avoid them drying out is to stand the little pots in a shallow tray with damp river sand or gravel, providing humidity for your little trees. However over watering will lead to root rot, so drainage is just as important as it is with larger trees.

One of the styles I've never tried growing is root over rock. I've always felt that the rocks will make them too heavy for me too handle. However Hennie showed us a miniature root over rock Ficus, so I guess I no longer have an excuse not to try this style.

Tall and Straight with No Low Branches

The saga of my family of Ficus Ingens continues.

In 2012 I bought my first Ficus Ingens - very ordinary nursery stock, approximately 3 foot tall and straight as a pole. I've already discussed the first 2 successful air layers as well as the air layering blunder which, despite my doubts, had a happy ending. I sold that particular tree at my club's annual show, but still have the rest of the family.

The parent tree has made some progress, though I'm still not happy with the branch structure, so I've made a few changes recently. The smallest one is doing well too, though it has a bad case of wire bite after I tried to put some movement into the trunk and, as I so often do, left the wire on far too long.

Unfortunately the tallest tree refuses to cooperate. After the second air layer I was left with a long straight tree with a thin new leader.

January 2017

That was two years ago.

The top has grown vigorously since then, but the tree has stubbornly refused to produce even one low branch. It's bonsai potential that way is nil.

In November I decided that the only option was another air layer.

Air layer, February 2019, just before I removed it

This time I layered the tree just below the clump of branches growing really close together. This, I hoped, would finally stimulate some lower growth. That never happened.

The layer has rooted well though.

Last week I decided it was time to separate the top and bottom.

The new tree in it's own pot

As the new tree has so many low branches I decided to remove the long straight section before it gave me another problem tree.

February 2019 - after pruning

Now I'll let it grow for a while before deciding on my next step. There are way too many branches there to keep them all, unless I try to fuse some to the trunk later on. Possibly I'll grow a multi-trunk tree.

I'm pretty happy with my summer's work, but I'm a bit concerned for the future of the base:

Base - February 2019

After it's stubborn refusal to produce any low branches, will this finally shock it into cooperating, or will it kill the tree? I'd hate to lose it.

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.

Naturally Stunted

This tree has never been in a bigger pot than its current home.

October 2018

It hasn't been repotted since it was a seedling either.

That's not the way I usually do things, but when a tree is too vigorous, stunting its growth has its benefits.

The tree above is the smaller of two Coral trees (Erythrina lysistemon) which I grew from seed about 8 years ago.

It's never been to a workshop, unlike its big brother which has been to a couple.

When I took the bigger one to its first workshop a few years ago, I felt compelled to get it out of its small pot because it kept growing so tall and top heavy that the wind was continually blowing it over. I took two pots to the workshop and was advised to put it in the larger pot. That's a decision I've come to regret because it grows much too quickly for my liking.

In April (autumn) I gave it a hard pruning to get it short enough to fit under frost cloth for winter. No styling was attempted at that time.

April 2018 - after rough pruning

I hadn't touched it since then and by last week the new growth was totally out of control.

October 2018 - six months growth

I decided to take it to a workshop, primarily because I knew that someone there wanted the thick cuttings. But first I had to remove most of the new growth so that it would fit in my car.

Cut back to a manageable size

After proper pruning it looks like this.

October 2018 - after pruning

I'll shorten everything further when I get some back budding.

Now I need to see that I keep its growth under control.

The little one was shortened in April too, but had produced much finer growth over the last six months.

October 2018 - before pruning

It needed a lot less work.

October 2018 - after pruning

Note that the fatness of both trees at soil level is pretty similar though the larger tree has gentler taper. The smaller one has a large bulge at the base, but that has been there since it was a seedling, so I'm not sure a bigger pot would have changed that. It also has no visible nebari, something that will have to be taken care of when I finally decide to move it to a more suitable pot.

But I fear that will have to wait until next year because it's a bit late in the season to repot it now.
