Background
This Jap murky pine comes from Aichi-En nursery in Japan. It belonged to my teacher, Mr Junichiro Tanaka till I bought it as a birthday contemporary to myself closing year.
Image caption. Wonderful birthday contemporary upright?
It had at some level suffered a injurious spider mite infestation and the tree used to be weakened by it. It also precipitated the total needles to was a lovely faded yellowish inexperienced.
Pointless to negate, I maintain no longer finished anything to it as at any time when engaged on a tree its survival of the plot outweighs all else. So if the tree you blueprint to work on is no longer solid to originate with, you are likely to weaken it extra by stressing it by wiring, defoliation or diversified such tactics.
Some pretty aspects of this tree
I love worthy trees. I jabber here’s why I love Jap murky pine loads, for me they mission an excellent deal of energy and maintain an staunch presence when on thunder. When walking by the nursery and Mr Tanaka indicated he would promote this tree to me I used to be straight enthralled by it.
- It has fantastic circulation; it appears it’s a yamadori.
- The fantastic shari factor on the tree is pure and in actuality weathered.
- The extremely thick bark plates provide clues as to correct how worn this tree will be. The nebari could be pretty fascinating, which usually is no longer the case with pines.

Contemporary recount of health
Image caption. Spring candles
With liberal applications of BonsaiBoost, closing rising season especially in Autumn, the tree has gathered ample energy to push out a form of solid, spring candles. That is a extremely perfect signal.
Image caption. The steadiness of energy of this tree needs to be restored
The energy on this tree is fully out of steadiness and in time this could well perhaps need to be restored by needle plucking and decandling tactics.
Selections
Akadama and pumice (Jap hyuga), the medium which this tree is planted into will originate to crumple after some years. Many of us leer this as a detrimental but indubitably it’s not. As soon as you occur to repot a tree you win away much of its roots, so within the weeks and months afterwards, you need the tree to jabber new roots so it would reinforce the canopy. Nonetheless after a couple of years you score no longer mild favor this solid mutter to continue because it turns into too no longer easy to administer the tree and end branches from was low and indubitably dropping ramification.
If the use of Akadama the particles score originate to crumple as ultimate roots are able to penetrate and split them and in so doing will cut lend a hand drainage. This ends in increased water retention. Each and every these factors lead to retarding the mutter of the tree.
On this trees case, the akadama has broken down to some level and ordinarily I would high-tail away the tree undisturbed for one other year or extra on the different hand before I can work on the tree I need it stronger. So the finest part for this is also to win away the worn soil and repot it the use of a extremely free draining, drier mix. On this case this could well perhaps consist of akadama, pumice and LECA in equal proportions. If I had been repotting a healthy tree the place development used to be practically total then I would maintain veteran 2 aspects Akadama, one piece pumice and one piece LECA or crushed stone.
Preparing the tree
The copper wire which had been veteran to fashion the tree a couple years within the past used to be mild on the branches. If the tree is to be positioned in a free draining mix in negate to promote swiftly mutter, I score no longer need to incur an excessive amount of wire chunk or that it turns into so extreme that it’s essentially a venture so I might want to win away the wire.
Image caption. Wire chunk already visible on among the branches.
Wire chunk on young pines is in actuality a technique which every at times could maybe well perhaps be veteran to promote thickening. The wired share will push out in opposition to the wire and in so doing will fatten. Clearly there comes a level the place here’s excessive and the wire essentially turns into misplaced within the bark. Ideally it is advisable to manual particular of the latter field from happening.
Image caption. Reducing the copper wire with a bonsai wire cutter.
Fortunately a chum of mine, Andre de Kok used to be form ample to support me in casting off the total wire from this tree. It is a ways fantastic how much wire a tree of this measurement and level of refinement can capture, and how much time is required to win away it.
It is a ways finest to cut wire the place that it is advisable to perhaps maybe well perhaps imagine, into shorter sections which could then be simply removed. Nonetheless whilst you occur to search out areas the place the wire has bitten in, it’s better to use a pair of pliers to rigorously win away the wire by uncoiling it. It is a ways thus finest now to not win away wire within the energetic rising season if the least bit that it is advisable to perhaps maybe well perhaps imagine, and whilst you occur to could maybe well perhaps need to ideally score so within the tail end of summer or better but, in autumn. That is because the reside tissue, the cambium can simply be separated from the hardwood underneath throughout the energetic rising courses. So when casting off wire which has bitten in, the bark also can simply be lifted on the the same time. When this happens it’s a ways finest to straight seal these areas with a gracious bonsai tree sealer to end as much sap/resin from leaking.

From an environmental consideration it’s a ways finest now to not merely discard of any worn wire whether or no longer copper or aluminium. Fairly separate it and win it in containers. It is advisable maybe well perhaps maybe then win this to the recycle depot, and likely even get a couple of cents for it!
Image caption. Some branches had died and had to be removed. A root cutter which is a extremely solid and sturdy chopping software program is my software program of desire for such projects.
Lifting the tree from the pot
Image caption. Using a repotting sickle makes it more uncomplicated to bewitch a tree from its pot
A repotting sickle is veteran to produce a minute gap between the root ball and the container. This makes it that it is advisable to perhaps maybe well perhaps imagine to maneuver the tree from the ceramic container without breaking it the container or the root ball. When working with extra priceless ceramics comparable to this one, it be critical to behave with warning in order now to not chip or pickle the pot with the sickle.
Image caption. Doing away with the tree
Gently but with deliberate action, I eased the tree out of the pot. When performing this the first step needs to be very cautious now to not interrupt off the bark. The bark which affords loads personality to this tree, had been it to be broken off, will win years to plan again.

Working the roots
Image caption. The muse ball being raked
Starting on the underside of the root ball, the roots are rakedto win away worn rising media.
Image caption. Reducing thick roots which maintain developed too long
As soon as you occur to attain upon a thick root which needs to be shortened the finest software program for the job is an appropriately sized root cutter. We would like to shorten these thick roots to promote a extra fibrous root machine with fewer storage roots and extra feeder roots. It is a ways these feeder roots which reinforce the trees ramification.
Image caption. Reducing the roots with scissors
Thinner roots which maintain grown too long could maybe well perhaps be cut the use of a pair of scissors. I would recommend a heavier responsibility scissors for this process, one thing esteem what I name the frequent bonsai scissors. Intellectual scissors esteem these veteran for trimming buds would no longer be appropriate as their blades are too pretty. Whichever scissors you use, score no longer use the the same pair with which you narrow branches. Scissors veteran the place there’s rising media contemporary will be blunted and was damaged pretty like a flash. For chopping branches it is advisable to perhaps maybe well perhaps maybe need to use a software program which is appealing and could maybe well perhaps mild make tidy cuts, which is able to heal over like a flash.
Image caption. Using a win to begin the root ball
Raking the roots will invariably lead to the loss of some roots. On account of this truth as you get nearer the dimensions of root ball which you raise to withhold it is advisable to use a software program diversified than a rake to work with. In the present day you are the use of an ice-win or the same software program. I made one thing from an worn screwdriver which I sharpened to a extremely blunt level the use of an perspective grinder.
The muse is to softly ease the win into the root ball and wiggle it a small bit to begin it up. This action ends in aerating the root ball which is extreme to its long timeframe health. Failure to score this step will mean that technique to the trunk the root ball will was extra and extra compacted. Fewer and fewer ultimate roots will reside on and the finest fibrous roots will be stumbled on on the perimeters of the root ball. Nonetheless sooner or later you can need to cut lend a hand no longer easy and then there will be no roots to cut lend a hand to and here’s particular to weaken and even execute the tree.
So working from the outer fringe of the root ball you work inwards, gently pushing the blunt implement into the root ball. On occasion you can arrive upon a root so are attempting from a diversified perspective. Invent no longer be in a drag and jab the software program into the root ball as this could well perhaps inflict damage on the thicker roots and could maybe well perhaps mild also damage the thinner ones. This step does win time but when finished properly the root ball could maybe well perhaps mild in actuality feel spongy. This now begin structure will enable water to penetrate and drain simply and for a need to maintain oxygen to penetrate.

Preparing the pot for planting
Image caption. After a transient tidy with a cushy bristle brush the drainage holes are lined with new mesh, which is able to end any loss of rising media.
Image caption. Drainage layer of medium sized pumice
Pumice is a big medium to use whilst you occur to score favor a drainage layer. It promotes swiftly drainage, holds some water but additionally affords a irregular, sandpaper-esteem ground over which roots seem to ramify readily.
Image caption. (Clockwise from top left) Leca for drainage but it is advisable to perhaps maybe well perhaps also use stone, medium sized pumice, medium sized akadama, ultimate akadama, ultimate pumice and carbon
The insist ‘moisture’ field is one the place the total pot dries at roughly the the same price no matter the zone (top or bottom). If the the same medium is veteran with out a replace in particle measurement no matter the zone, you can likely choose up it dry on top and wet on the underside. This means that in negate to end the ground roots from drying out altogether it be critical to water again, but this suggests that the underside zone in no design will get shut to drying out. Some trees esteem the pines grow finest when the roots are on the dry facet. Maples as an illustration, in distinction, score no longer love to get too dry and could maybe well perhaps mild dwell practically continually on the wetter facet of moist. It is a ways for this aim that it’s not as critical a consideration to use varying particle measurement with deciduous trees because it’s with conifers as “they score no longer love wet feet.”
Image caption. The heart zone, medium sized Akadama and medium sized pumice
Within the heart zone, or heart 1/third of the pot I maintain veteran a mix of medium sized Akadama and pumice. The Akadama at this level is supposed to withhold extra moisture but but provide fantastic drainage and oxygen replace.
Potting the tree
Image caption. When repotting stand lend a hand and ascertain the planting perspective
Having a further pair of hands for this repotting used to be the kind of mammoth aid. Andre is seen above keeping the tree in location so I could maybe well perhaps ascertain the planting perspective. As soon as you are cheerful then the tree’s location could maybe well perhaps be fixed by the use of wire, inserted by the supplied holes for the aim within the pot or by the drainage holes.
Image caption. The end layer is made up of finer field cloth
The finer (smaller than 6mm) grades of akadama and pumice had been veteran for the head layer. Smaller particle sizes mean smaller gaps between particles but extra storage capability for moisture.
Receive particular to work the rising media into the total cavities so that no tremendous air pocket dwell. Within the image above it is advisable to perhaps maybe well perhaps leer a blunt metal rod being veteran. It is advisable maybe well perhaps maybe on the subject of use anything, I usually win extra chopsticks when I get sushi and use these. True make sure that the tip is blunt so that no roots are impaled whilst you occur to work the rising media in.
Watering and aftercare
Image caption. Watering within the tree with a ultimate spray wand
As soon as you are particular that you would need labored within the soil properly the tree could maybe well perhaps mild be thoroughly watered. As the ticket of Akadama that I promote is of excessive fine there’s in actuality very small dirt but it’s a ways finest to water till the water working from the drainage holes is as particular because it’s straight from the faucet.
Pines depend on daylight hours reaching their needles in negate to form energy so it makes small sense in inserting a nowadays repotting pine in shade for too long. This is able to maybe well perhaps simplest aid to weaken it. The greatest part it is advisable to perhaps maybe well perhaps maybe mild win precautions in opposition to is wind. Wind can unsettle the tree and produce minute actions of the tree within the pot, here’s why securely wiring it into the pot is so critical. These actions could maybe well perhaps inflicting damage to young roots, depleting the trees energy property even extra. So location the tree in a sheltered, sunny location.
Akadama is gigantic because it changes to a dejected brown color when wet and so it’s pretty straightforward to peep when the tree requires watering again. It is a necessity to enable the rising medium to dry out to a level. Indecent water will retard the formation of feeder roots and as a replace lead to sparse, coiling roots.
Fertilizer will be withheld for the major few weeks and then a couple of bags of BonsaiBoost will be added. When a tree is in a weakened recount it’s in no design a gracious blueprint to actively are attempting to promote mutter by fertilizing, pretty answer to the trees mutter by supporting it with fertilizer. Clearly any fertilizer utilized to a tree which has correct been repotted and has few feeder roots with which to win up the vitamins will merely be wasted anyways.
