A Little Fall Color – Not Too Common Here

The only thing I envy about my fellow bonsai artists from up North is the fall color they get to enjoy on their deciduous trees.  In the Deep South we typically don’t get a lot of fall color.  When we do, it arrives suddenly – this weekend for 2015, to be precise – then the leaves all fall within a few days and winter ugliness begins.  I was pleased this year to see a little fall color in my garden, and wanted to share a couple of trees with you.

Sweetgum11-29-15Here’s the sweetgum I recently posted for sale.  One reason I love sweetgum is that it’s one of only a few species that will actually produce reds and purples in fall down here.  We mostly get yellows and browns, which are certainly attractive in their own right but you just can’t beat the reds and purples in my opinion.

Here’s my “root around cypress knees” water-elm.  It’s in need of a trim, but I wanted to show it before pulling out the shears since I knew I’d knock off a lot of the leaves in the process.  This is typical water-elm fall color.  I sometimes get it, but most of the time don’t.

And after a quick shearing.  These remaining leaves may hang on for a few days; but for now, they look really nice.

Another Promising Water-Elm For 2016

I wrote before on my new experience of collecting water-elms, Planera aquatica, in October.  A number of the specimens I brought home have shown new bud activity, though late in the season of course.  There won’t be shoots from these buds, but their appearance tells me the trees have maintained their cells’ internal pressure going into dormancy.  For those of you with some experience collecting trees, you know what sap withdrawal looks like.  Smaller branchlets become brittle (in many cases you can actually see the juvenile bark wrinkle from dehydration).  Once this process begins, you can pretty much count the tree as dead.  On the other hand, those trees that are going to make it maintain their cells’ internal pressure, or hydration, and sap flow is re-established with the growth of new roots and then shoots (sometimes this is reversed, but sap flow is what pushes the new roots and shoots).

Water-elm10-18-15-1You may remember this tree from October 18th.  It was the biggest one I brought home.  As I noted at the time, I always do my best to bring home one big hunky masculine specimen from each trip.  This one fit the bill.

Fast-forward to now, and this specimen has roots emerging from the drain holes of its pot.  It’s also pushed a few new buds, which won’t grow any further this year.  But the fact that there are roots tells me the trees’ cells are well hydrated.  Barring something unusual happening this winter, this tree should explode with growth come spring.

 

 

Water-elm11-28-15

 

 

Here’s the tree today.  It’ll go on sale next spring.  The trunk is 5″ at the soil surface (flaring roots are buried, as usual), and it’s 31.5″ to the chop.

Good Boys Do Fine Always – Playing Your Bonsai Scales

Winter is no excuse to stop practicing our bonsai scales.  By this, of course, I mean the continued practice of techniques that help us get better and better at designing and developing our bonsai.  And along these lines, I’m a big proponent of practicing on less than stellar material.  Why?  Well, when you get down to it there’s never been a bonsai that didn’t start out as less than stellar material.  All of our trees have to grow, get whacked back or chewed on, suffer drought and/or deluge, and one day they look like something we really want on our bench.  In the meantime, however, there are those little trees that won’t make you look twice.  These get the “treatment.”

Privet11-25-15-1Here’s Exhibit A, otherwise known as less than stellar Chinese privet, Ligustrum sinense.  This isn’t a terrible piece of material, but it does have its issues.  The biggest one is the fat base with the shoulder, that narrows into the main part of the trunk too quickly.  Now, this is a nice practice piece.  There are problems that can be solved, and when they are the material will be much better.

Privet11-25-15-2

 

 

 

 

 

A few minutes later, the overlarge base has been whittled down so it looks like part of the tree.  This is very straightforward, but I can’t tell you how often I’ve had students or demo observers amazed when I attack a piece of material so aggressively.  To be sure, not all species appreciate rough treatment.  But once you start learning the individual habits of different species, especially the types of work you can safely do at what times of the year, you can get actually away with a lot.

 

 

Privet11-25-15-3

 

 

 

 

The next problem with this tree was the odd branch sticking straight out near the original chop.  A quick whack and some nibbling with the knob cutter solved that problem.

 

 

 

 

 

 

Privet11-25-15-4

 

 

 

 

 

And finally, I removed everything that didn’t look like a future Chinese privet bonsai, wired and positioned the branches.

Hey, it’s not awesome material but it’s a lot closer to stellar than before.  This one can go into a bonsai pot next spring.

 

 

 

American elm11-25-15-1

 

 

 

Just so you know I know what really nondescript material looks like, here’s Exhibit B, an American elm, Ulmus Americana, that began as a single trunk nondescript specimen a few years ago, after which it dried out and died back to the base (at which point I threw it on the discard pile, thinking it was totally dead), after which it sprouted two shoots from the base and I felt compelled to save it.  This is the end of year two of the regrowth of this tree.  There’s really not much to it.  But as you develop pre-bonsai from seed or cuttings, you learn various techniques for developing trunk size and character.  In the case of this specimen, I need some movement in the swelling trunks.  So I put some fairly heavy gauge wire on each trunk.

American elm11-25-15-2

 

 

I didn’t try anything fancy here, just put a little curve in each trunk.  Notice, however, how I’ve started this design.  The trunks move in harmony with one another.  The left-hand trunk is destined to be more upright, which means the right-hand trunk needs to sweep a bit farther to the right.  This is what would happen in nature, as the right-hand trunk needs sufficient light to thrive.

The wire on this little tree will need to come off next May at the latest.  I expect pretty rapid swelling when growth gets underway in spring.

For those of you wondering, Good Boys Do Fine Always is a mnemonic that helps music students remember their notes.  That’s right, I was a band geek many decades ago.

Dreaming Of 2016 – American Hornbeam Work

Hornbeam11-24-15-1I think this is a significant American hornbeam (Carpinus Caroliniana) bonsai in training.  With a trunk base measuring 6″ near the soil surface and a projected final height of 30-32″, great nebari and taper, and characteristic muscular trunk, what’s not to like about this tree?  Nothing, really.  But there’s a lot of work that needs doing as this bonsai enters the next stage of its development – it was dug in Winter 2010, got an initial wiring once new shoots had formed that same year, then was initially potted three years ago.  During this time I worked on building the tapering transition in the apex, grow-and-chop by grow-and-chop.

This tree needs repotting next spring.  It could have been repotted this past spring but I had other, more pressing chores.  (Hornbeam roots very vigorously, so I generally recommend repotting every second year.)

Before I pull the tree from its pot, however, there are some significant chores that need doing.  If you look closely at the upper trunk area, the tapering transition is not at all bad except for what looks like a “shoulder” where the original chop was made.  This basically needs to be carved down to make the transition look better.

Hornbeam11-24-15-4Here’s a closeup of the area I’ll be carving in the apex.  It began as a straight chop when the tree was first collected.  Once the new leader had grown strong enough, I made an angled cut.  Once the healing began, I did some initial carving of the wood inside the rolling callus.  That was four years ago.

Now I need to undertake the next carving project in this area.  By angling the cut downward and taking off the “shoulder” on the left-hand side that makes the tapering look awkward, I should get the appearance I want.  It’ll take several years to heal the way I need it to, but that’s not a problem.  Time is always on the side of a maturing bonsai.

Hornbeam11-24-15-3Here’s another carving project whose time has come.  When the tree was originally collected, there was a second trunk emerging from the spot you see in the photo (it was hollow inside and destined to die, and certainly of no use to my design plan).  I cut it back, but was careful not to make the cut too close to the trunk in order to prevent dieback down the trunk on that side.  I was blessed with a bud beneath it, in a great spot for a primary branch and available to feed the roots on that side.  I’ve worked on that branch since and refrained from carving the old trunk stump so as not to risk its health.  Spring 2016 will be the time to take it back with my Dremel®.

Hornbeam11-24-15-2As with any tree, there are always minor problems that eventually bother you enough that you decide to correct them.  In the case of this tree, I have a thick branch in the crown of the tree and a bit of reverse taper in one of the apical curves.  I think both of these problems can be solved without overly dramatic cutting; but I’ll make these decisions next spring while everything else in happening.

 

 

 

 

Hornbeam11-24-15-5And finally, just to complete the record, a shot of the tree from the back.  I’m very pleased with this hornbeam specimen; it’s truly one of the finest pieces I’ve worked on in my bonsai career.

Let me know what you think of this tree.  I’d love to hear from you.

Building A Chinese Elm Bonsai – Year 1

Chinese elms, Ulmus parfivolia, grow quickly in the ground and this is how I grow all of my Chinese elm material with the exception of trees intended for forest plantings.  In 2014 I lifted a specimen I’d had in the ground for a few years to see how quickly I could move it from raw material to presentable bonsai.  The lift was made in late winter, and I put the tree directly into a bonsai pot (which I knew would slow down the process, but that didn’t concern me).

Chineselm8-4-14In August of last year, the chopped stump had produced shoots long enough to be wired, and I had a good enough set that I could create a suitable structure right from the start.

It doesn’t look like much, does it?  But every bonsai begins with a tree that has either grown in the wild from a seed ultimately becoming a stump/trunk/clump/etc., or in “captivity” from seed or cutting, or in the ground from seed or cutting with more or less management by the grower as it develops.  Having grown many hundreds of bonsai through the years, the prospect of taking a bare trunk all the way to a finished bonsai does not discourage me in the least.  In fact, it’s one of the more pleasurable pursuits I can think of.

Following this initial styling, I simply left the tree alone (being mindful of the thickening of branch and leader so as to remove the wire at the proper time) for the rest of the 2014 growing season.

Chineseelm7-5-15-1This is what had happened by early July of 2015.  I needed the strongest growth in the new apex of the tree, and that’s just what I got.  Though the tree would have grown this way on its own, trying to get taller, I helped the process along by keeping the energy in the lower branches directed toward ramification.  The structure of each lateral branch was easily built during this growing season.

Chineseelm7-5-15-2The next step for this tree was to cut back the new leader in order to ensure that the tapering transition at the original chop, roughly 9″ from the soil surface, would end up looking right.  The trunk as lifted had gentle taper, not as dramatic as I may have liked, so the trick in finishing out the trunk will be to continue the gentle taper yet bring it to completion at a final height of about 16″.

 

 

After the chop.  This looks pretty funny, doesn’t it?  But building taper in your trunk or branches requires cutting back hard after a period of unrestrained growth.  It’s how this trunk got to where it was before I lifted it.  So after allowing the leader to grow for almost a year, I had a long section measuring almost 6″ which had zero taper.  What’s more, I had only one way to induce taper into this section of new trunk, namely letting sacrifice branches grow.  While this was certainly doable, it wasn’t the fastest or even the best way.  Growing a new leader was the obvious choice.

Chineseelm11-22-15

 

In this final photo you can see the next stage beginning for this tree.  I got a few buds on the truncated leader that I allowed to grow unrestrained.  Since it was late in the season, they were only able to extend about 6″ before dormancy hit.  But in 2016, I’ll let one of them run wild and I’m betting the original transition will start looking much better.  The thickness of the first new leader should double next year.

So this is a year in the development of a Chinese elm bonsai.  I expect that in another two years I should have the rest of the trunk built, along with a lot more of the lateral branching.  By year four, this tree will be fully built.

A Winter Storage Container

Winter storage of my bonsai is exceedingly simple: everything on the benches until temps reach 25° F; everything on the ground below 25° down to 15°; everything covered with poly sheeting below 15° down to 10°; fervent prayer below 10°.  Okay, only kidding about that last one – in addition to the prayer, I would mulch and cover everything.

So that’s down here in the Deep South, but many of my clients live in harsher climate zones.  I’m often asked about winter protection for a variety of species, and I usually suggest an unheated garage or cold frame abutting a house.  The unheated garage has its limitations, of course.  The cold frame may or may not provide adequate protection if your winter temps will go below zero.  And if you grow tender species, your problems get somewhat larger.

I have a long-term client who just turned 88 – isn’t that awesome!  He’s been experimenting for the past few years with a heated winter storage container that he constructs in the fall and in which his tender bonsai remain until spring has arrived.  I asked him to give me some details of his construction method, so I could pass the information along to those of you who live north of Zone 7.

The basic concept is simple: build a six-sided Styrofoam® container and equip with an oil heater (an electric heater should work as well), then maintain your winter temperature at 35°F.  Building the container, of course, requires planning and effort.  This post will give you some details on a reliable way to protect your tender bonsai through winter.

Winterstorage1A critical step in prepping the Styrofoam panels is to glue on some tabs so they hold together.  You cut small blocks and use 3M® spray glue to affix them to the panels, as in the photo at left (the 3M spray glue is a critical element; regular super glue does not work).

Bonsai Design – Going With The Flow

Creating Deadwood Bonsai – Even When You Hadn’t Planned To

As you pursue the art and craft of bonsai, it’s a sure bet that all of your design ideas will not be realized.  While this may sound like a bad thing – we’re in charge of designing and developing our trees, after all – it’s not necessarily bad.  If you’ve done any significant collecting of material for bonsai, you’re bound to have run across trees with odd enough (but really cool) “designs” that you would never have thought of if you had had total control.

So, too, it often is with trees after they’ve come into our care.  We begin with a design plan, which is usually given to us by how the tree has chosen to grow.  We dutifully wire and shape branches and new leaders and wait patiently as the designs take shape.  Most of the time we get what we set out to do, at least in the beginning.  But on occasion a tree will decide to give up a branch; sometimes a storm makes a change we didn’t have in mind; sometimes a family pet or wild animal enters the design picture.

Loblolly10-3-15-3You last saw this loblolly pine bonsai, Pinus taeda, back in early October.  I noted at the time that the first left-side branch needed chasing back in, as it was simply too long for the design plan.  What I didn’t notice at the time was that the branch was simply weak; why, I don’t know.  So the tree made the decision for me in regard to being overlong; it let the branch go.

 

 

 

 

Loblolly11-16-15-1

 

 

 

 

Here’s the difference a month made.  There’s been no harsh weather, no unusual dryness, no insect attack.  The branch just died.  This happens in the wild, as well.  We just took a vacation road trip, and I couldn’t help but notice countless pines along the way (mostly loblollies, as it’s the predominant pine species in the Deep South) that had lost just a single branch.  So at this point I’m willing to conclude that it’s not unexpected for this to happen with the species.  I haven’t been working with loblollies but for a few years now, so I’ll learn more in time as I gain additional experience.

Loblolly11-16-15-2So a design decision has been made for me, which it turns out won’t be bad.  This is because coniferous bonsai look older and more mature with dead wood features – primarily jin and shari.  This tree lost a branch; time to make the most of it.

 

What follows is a tutorial on creating deadwood bonsai – which primarily consists of jin and shari, but in this case is limited to jin.  Now, you don’t have to wait for your tree to lose a branch in order to add jin.  With that said, however, you have to be as diligent in designing a jin or shari feature as you are in building your tree’s structure.  Most of the time, less is more (this rule obviously does not apply to certain pine or juniper bonsai that are built around extraordinary natural deadwood – you’ve no doubt seen pictures of such specimens).  In the case of my tall, graceful loblolly pine, I don’t need a lot of dead branches to make the appropriate artistic statement.

First of all, you only need three tools to create jin on your trees, and every bonsai artist must have these three tools regardless of the type of work planned: concave cutters, wire pliers and a sharp grafting or X-Acto® knife.

So let’s begin learning some basic deadwood bonsai techniques.  Step one is to simply shorten the dead branch.  Not too short, but not too long either.  This looks about right to me.

Loblolly11-16-15-3Step two is bark removal (in the wild, the bark eventually falls off dead branches as they dry out before ultimately become bleached out by the elements).  This is a two-part process, the first part of which is to cut through the bark completely around the branch as its base – you use your knife for this operation, as I’m doing here.

 

 

 

 

 

 

 

Loblolly11-16-15-4

 

Next I take my pliers and, gripping the bark along the branch, crush and twist it until it separates from the wood beneath.  For branches that are either still alive when turned into jin or recently dead, the bark comes off very easily.

 

 

 

 

 

Loblolly11-16-15-5

 

 

 

 

And the result….  Isn’t it interesting how much of a difference this already makes in the tree’s appearance?

 

 

 

 

 

Loblolly11-16-15-6

Step three is making the jin look believable, that is, not like someone just killed the branch, shortened it and removed its bark (which I did).  This again is a two-part process, the first of which is to make two longitudinal cuts, at 90° angles to each other, into the tip of the branch.  To do this, use your concave cutter as I’m doing in this photo.  Don’t cut too far in along the branch; just enough to allow you to grip and separate three of the four segments by peeling them back with your pliers.  This makes the jin look more natural.

 

 

 

Loblolly11-16-15-7

 

 

 

 

 

Now, with your pliers carefully grab one of the segments at its tip and peel back toward the trunk.  It’ll tear roughly along the direction of the longitudinal cut you made in the previous step.  Repeat this process with two more of the segments.  As you tear back the wood, be sure that you taper it into the branch so that it looks more realistic.

Finally, use your carving knife to complete the tapering down to a sharp tip.

 

 

 

 

Loblolly11-16-15-8

 

 

 

This is the completed jin.  It needs to dry out for a week or two before I apply lime sulfur to whiten and preserve it.

 

 

 

 

 

 

Loblolly11-16-15-9Here’s my loblolly pine, redesigned to make use of the dead branch.  Compared to the original photo above, I think the tree is much improved.  What do you think?

The Envelope Is Pushed

Hawthorn11-7-15A couple of weeks ago I published a photo of this riverflat hawthorn, Crataegus opaca, I collected on October 10th.  There were tiny buds at the ends of some of the branchlets, which clearly were viable and indicated this tree was likely going to survive collecting.  I had no real concerns about the tree.  At the same time, however, I didn’t expect much more going into fall dormancy.

Imagine my surprise today when I saw a bunch of adventitious trunk and branch buds pushing.  I certainly figured this was what was going to happen next spring, but to see the tree making a move now was a real eye-opener.  What’s going to happen next?  There should be modest growth all the way till our first freeze, which should come next month.  I doubt this new growth will have time to harden off, but at the same time I don’t think the tree will be affected by it.  This tree looks like wanting to live.

Water-elm11-7-15-1And speaking of pushing the envelope, a bunch of my new water-elm collects are now budding.  Here’s one of them, trunk base 1.75″ and 11.5″ to the chop.  This tree will be mostly developed in 2016.  Great trunk movement and a nice root base.

 

 

Water-elm11-7-15-2

 

 

 

 

 

 

This one is a lengthier project, but just a couple extra years should do the trick.  Either two or three trunks, the main one is 2″ in diameter and 9″ to the chop.  It and the number two trunk need developing, but this goes fast with water-elms.  I like the start I have with the movement of the main trunk.
