Introduction to Proper Bonsai Defoliation
Defoliation is one of the aspects of bonsai artistry that made no sense for several years . The result was an unhappy artist unable to germinate one of the key to good bonsai husbandry – branch and diminished leaves .
After trying several other approaches , I finally discovered how to fulfil effective defoliation .
Let me apportion the secret of good bonsai defoliation . The nutrition transmit principles share here can also be apply to other crops .
The main end of bonsai tree - making is helping a plant arise into what it would in the natural state — a tree in equilibrium with its surroundings and an of the essence element of the world .
We ’re merely repeat the splendour of nature in a midget contour .
Collaborating With Basic Biology
Every autotrophic plant postulate H2O , lightness , and 17 canonical chemical substance elements to farm . autophytic plant are plants that make their intellectual nourishment by photosynthesis .
These plant life utilize sunshine , water , and the gases in the air to make glucose , a shape of carbohydrate that plant require to survive .
To do photosynthesis , plants need three things : carbon dioxide , water , and sunshine .
The energy from the light causes a chemic reaction that breaks down the atom of atomic number 6 dioxide and water and shake up them to make gelt ( glucose ) and oxygen natural gas .
After the clams is produced , it is break away down by the mitochondria into energy that can be used for growth and fix .
If we were to write a chemical formula for photosynthesis , it would seem like this :
6CO2 + 6H2O + Light energy → C6H12O6(sugar ) + 6O2
The whole process of photosynthesis is a transfer of muscularity from the sun to a plant . In each sugar corpuscle created , there is a little DOE from the Sunday , which the plant can apply or salt away for later exercise .
A key factor of this dealing and process is the presence of leaves . After all , the leaf are the plant ’s solar panels ; without them , the plant will run out of energy and famish .
Of course , there are exceptions to the pattern – non - photosynthetic plants , but you ca n’t habituate them for bonsai cultivation as they ’re fundamentally sponger .
Which Bonsai Trees Can Be Defoliated?
Most deciduous trees can be defoliate if they ’re not still in training or have undergo late repotting , pruning , or other factor that have compromise their resilience .
Defoliation can also be used to control development in finical tree diagram segments ; for object lesson , you might defoliate the top of the Sir Herbert Beerbohm Tree while leaving the bottom untreated , restoring balance to the tree .
Best Time To Defoliate Bonsai Trees
The optimum time to defoliate most bonsai tree metal money is in former May or former June , giving the tree diagram enough time to produce new leaves and prepare for wintertime .
Defoliate when the new outpouring growth has harden off , depending on the eccentric of tree .
The 3 Stages of Defoliating Your Bonsai
Bonsai Defoliation Stage 1: Leaf Removal
This first footmark is easy : cut the leaves off , severing them at the petiole ( supporting root word ) with sharp scissors . The remaining root word will dry out and fall off in about a hebdomad .
Most species will experience damage if leaves are removed because this can also off some alar buds and even very minuscule strips of bark from some mintage . dispatch the entire leaf in this situation ; only part wo n’t do .
If the current time of year ’s filename extension ’s tiny rotund primary leaves are too small to trot , leave them for a later culling .
Always start from the top , work your means down , being more aggressive with strong growth and less so where growth is weak and would profit from the intellectual nourishment production .
If sure branches of your tree diagram are really weak , you might choose to leave a few leaves . Leaves on small inner or low branches might be eligible for defoliation , but be decisive .
hapless results result from taking half measures .
Bonsai Defoliation Stage 2: Growth Pruning
After the leaves have been pluck , prune the unexampled growth to mix in with the rest period of the tree ’s structure , selecting your buds . This pruning process is interchangeable to what you would do in the nightfall or properly before natural spring flush .
The goal is to opt for branch direction modification , so reduce the offshoot to single divergence . off the spindly shoot at every fork , leaving an option for the ramification to strengthen a new branch .
If a ramification ’s bodily structure is incorrect , it will have to be eliminated later on , so do n’t ’ bother growing it .
call back that the fork order is exponential ; one becomes two , two becomes four , eight sixteen , and so on . That is how ramification is constructed .
After pruning and bud selection , it ’s time to apply wire to make structure . Most broadleaves are like putty at this stage and can be bent and positioned in a affair of weeks .
I use the chance to plant newfangled growing where necessary and meek branch turn out of ascendency .
Take advantage of the chance to widen gap so visible light can embark the interior structure . At this level , a broadleaf tree diagram build , developing a dead on target - to - nature character . Phase 2 is crucial !
I like to keep the tree diagram in the greenhouse for at least a week once this work is end up . The increased temperature has a significant encroachment on the new kick of foliage .
As soon as I mark the large saucy buds put to bloom , the Sir Herbert Beerbohm Tree revert to its common placement outside .
Once our Sir Herbert Beerbohm Tree redden fresh growth , ordinarily a month after stage one , please leave it to grow three or four leaves . This growth is indispensable for the tree ’s general eating and maturation .
Allow this development for six to eight weeks after stagecoach one of the defoliation process – in the Northern Hemisphere ; this will take you somewhere in August .
The plant has had some metre to grow and benefit from the available leafage , so you’re able to now cut down the new extensions to one or two nodes and take a good percentage of bigger and low - hang leaf .
This third stage of defoliation launch the tree ’s structure , admitting more light into the parts generally not exposed . At this point in time , you may remove the added conducting wire – assuming it was apply correctly and the chassis are utterly ready .
From here until fall , check you optimize growth factors – near fertilizing , piddle , and enough Dominicus . This ensures the works can get the reserve for winter and a good season next year .
This last point is somewhat different from what might hold to cheery regions . If you are totally produce indoors , pruning can happen earlier , as can later uprise flushes .
It would be best to utilize every here and now in low - light regions to create decent bonsai trees .
In Summary
Defoliation in June result in a powerful new heyday within a few days . The new flush is hard with powerful extension , near color , and good back budding .
The fresh leafage stay strong and vibrant until it receive significantly cold , which is late into November in my part of the humankind .
I have seen this happen so many times with unlike coinage now . Rather , it debunks the opinion that defoliation weakens a tree and , done correctly , the opposite is true .
For some plants , defoliation is not the best option . Hawthorn , Chinese elm , beech , deciduous oak , and a large bit of belittled leaf shrubs , in my personal experience , will grow inadequate consequence .
Even Privet wo n’t make much of a difference in our unexceptional weather , and a modified approach is needed for many type to raise their best results .
If in doubt , try it as long as your tree is inflexible , then honor the outcomes over the winter that follows .
Frequently Asked Questions
Why do you defoliate a bonsai?
You would defoliate a bonsai to refine the tree by increase fork . It reduces the size of the leaves , which help with balance and athletics , Makes wiring easy , and produces unattackable growth for fall .
How do you defoliate a tree?
There are two way to defoliate a bonsai tree diagram , Leaf by folio using scissor grip or pruners and stripping ; stripping involves escape a closed hand from the boneheaded part of the ramification out to the crest strip down the leaf .
When should I defoliate my bonsai?
The best time to defoliate a bonsai tree diagram is late May to early June . Quicker foliation trees like maple can be done to the latter part , while oak that takes a trivial longer should be done in former May . Only deciduous bonsai should be defoliated .
Do bonsai tree leaves stay small?
Bonsai Sir Herbert Beerbohm Tree foliage will stay belittled if you defoliate your tree diagram regularly . The leaves will turn back to their born size of it if allowed to grow without defoliate . Defoliation tending in the fork of the branches , which also helps keep leave small-scale .
Can a tree survive defoliation?

In Closing
As we can see , defoliation is NOT an elective process you may utilise , and it ’s the quintessential bodily process required to create bonsai trees from broadleaf species .
If you are not following the rules of bonsai defoliation , you are not creating a bonsai tree ; you ’re simply apply topiary ( the art or practice session of clip bush or Sir Herbert Beerbohm Tree into ornamental shape ) .
