- Lesson #3: PRUNING!
If you've taken your time to study your tree and it's growing well, you should be raring to go! But again, I recommend slowing down to test your gameplan against all other possible alternatives. While each bonsai will be unique, there are several basic alternatives that you should consider before you lock in your gameplan. There are unlimited styling options and this is the essence of bonsai!
UNDERSTANDING "BUILDING" CONCEPTS!
When a seedling sprouts, there is usually just a single growing tip. As long as that tip is growing well, no other tips develop until the plant is taller. Bonsai requires trees that have low branches and the standard method is to do a very early pinch to remove the primary growth tip to force new growth points. This is drastic for plants and many die. But without this step, plants do not develop character. You can improve the success rate with very healthy vigorously growing plants. Grow a lot of plants, grow them in the best possible environments, then prune drastically for outstanding results!
FUKU-BONSAI "SUMO" TRAINING
"SUMO" training produces outstanding plants that have very heavy stout trunks, strong low branches, and great trunk taper. Often there are multiple trunks, an excessive number of branches, and exceptional vigorous growth. Several key factors produce outstanding plants:
1. GROW A LARGE NUMBER AND SELECT ONLY THE BEST! If you grow 10 plants and eventually select just one, you'll have 10 times the odds of a good quality starter than if you grew just one! At Fuku-Bonsai, we grow millions and cull ruthlessly to produce outstanding stock.
2. PRUNE DRASTICALLY! If a plant is 12" tall and pruned to 6" high it's a lot better than no pruning at all. A plant pruned to 3" tall is better. Fuku-Bonsai prunes between 1/2" to 1" to produce highest quality plants. When you prune drastically, a lot die, and that's a form of culling as you're automatically eliminating the weak plants.
3. SELECT PLANTS THAT RESPROUT STRONGLY! If you cut the initial primary growth and just a single new growth point appears, throw it out! Your plants either are growing too poorly or are poor plant material. Its simply impossible to create compact branchy trees if your plant doesn't branch well. At Fuku-Bonsai, we also throw out those that only produce two new growth points as that's not good enough! Our minimum plants have three regrowth points. Those with more growth points are selected for larger premium products.
4. CREATE MEDIUM SIZE BONSAI FROM SUPERIOR SMALL BONSAI! High quality larger bonsai are much easier to produce if you start with the highest quality material. So select only the best smaller trees to train into larger bonsai. By the same concept, create large bonsai only from superior medium size bonsai! Because of this selection process over many years, our Custom Collection are all trees that have proven potential selected over 10 to 25 years. Poor quality stock end up as old poor quality bonsai.
5. RETAIN AS MANY TRUNKS AND BRANCHES AS POSSIBLE! Too often bonsai are skimpy plants that have been "bonsaied" with just a bare minimum of branches. That limits training options. Ideal bonsai trees should have extra trunks and branches simply because it is easy to prune off but a lot more difficult to add a branch where needed. Glue doesn't work; grafting takes a lot of skill. The common sense alternative is to start with good material!
6. CREATE THE OPTIMUM PLANT GROWING ENVIRONMENT! Too often there are "bonsai experts" that know everything about bonsai except how to grow plants! Without strong growth, there's limited progress. There really are no magic tricks. Grow plants that are well suited for your environment or change your environment to meet the needs of the plants. Appropriate trees that perform well will be much more satisfying than having a unique tree that no one else has. Common plants are common because they survive. Rare plants are rare because they are hard to grow and keep dying.
7. DON'T COMPETE! Bonsai should not be a competition, but too often it is! People want to own an old plant and brag about how old it is (or how much it cost). Bonsai competitions are stacked in favor of the old-timers who have been doing it for years, or the wealthiest who could afford to purchase the best material. If you're competitive, you won't assist others or share your "secrets."
8. ENJOY THE JOURNEY! Bonsai are like children. Each is unique with a different personality and potential. At it's highest level, bonsai is man and nature in harmony where a skilled trainer brings out the unique qualities of a specific tree. There's a pure relationship in which the trainer intimately knows the tree, its health, and its strong and weak points. In an enduring long-term relationship, the trainer strives to accentuate the strong points and offset the weak points. But the bonsai is loved as an individual. Perhaps no one else will appreciate a tree. But the owner-trainer does, just as every good parent loves each of their children.
These are the principles behind Fuku-Bonsai training philosophy. If you agree, read on.
STEP 1: STARTING OFF
Allow the seedling to grow, then cut back hard. How hard? It depends on you and your willingness to take risks. It's safer to prune higher up but you'll get superior results if you prune lower and the plant survives. Seal the cut with vaseline. Some people never get past this stage. They just don't have the confidence to do high risk pruning. Many Fuku-Bonsai customers prefer to avoid this stage and purchase starters that may be somewhere between step 2 and step 3.
Step 1 is the key to success! At this stage of training, install as much variations as possible. Root prune the tree while still very young to remove the tap root and to begin to develop an ideal compact root system. Plant the tree at an angle to get a more interesting base. Plant two or more trees together. Start off with as may variations as possible so each tree will be different!
STEP 2: DEVELOPING THE FORM
If you cut and only one or two new growth points appear, something is wrong and you should stop and first learn why. Can you obtain more suitable plants or seeds? Can you improve your growing environment? Are you watering and fertilizing properly? At this early stage of training, plants must be heavily fertilized and be growing very strongly. How much fertilizer? Enough to get good growth but not too much to kill it!
So how do you find out? Line up a dozen plants and fertilize one plant with what you think is the right amount. Next week add the same amount to the same plant and to a new second plant. Next week add the same amount to the first plant, to the second plant, and to a new third plant. Keep going until the first tree dies. If the second tree also dies, you'll pretty much know how much is too much. This is something that must be learned from experience. It's valuable knowledge in producing the best possible growth and healthy plant stock!
From the three or more new growth points, select the ones in the positions you like and remove the rest. Allow these to grow at least 7-8 leaves each before it's time to cut back again. If you do "step 2" several times, your tree should be ready for step 3.
STEP 3: REFINEMENT
Fuku-Bonsai's #8 size Living Sculpture, medium and large size Hawaiian Lava Plantings and our Custom Collection items are in this stage of growth. Generally it takes at least 8-10 years to get to this stage and our customers recognize that this is our more costly but best value products. The #8 size Living Sculpture and medium and large lava plantings are ideal for moving up with a #17 Conversion Kit to enlarge the root system to again begin another major growth stage. But in many ways it's an easier challenge as the high-risk pruning and aggressive culling is already past.
If you understand the above sequence of how a tree developed its form over the years, you'll be in a better position to continue to maintain the shape of your tree, to improve it, and to even restyle it. Fuku-Bonsai's primary "sumo" training technique produces stout trees with outstanding rootage, heavy trunks, and an abundance of branches. They are the finest quality plant stock available internationally for growing indoors. That's a large claim and it's true! They are the best simply because no one else is willing and able to grow them to the same high standards.
If you are privileged to start with such exceptional material, you should study if carefully before you do any pruning. First figure out how the tree was trained to get to that stage. Realize that it took many years and many prunings to develop. If it took 8 to 25 years to train, it would be a shame to restyle it after looking at it for just a few minutes! Regrettably, over zealous trainers have pruned off what took years to create.
Japanese bonsai standards begin with an appreciation of the roots, how they hug and rise out of the ground. Trees with poor rootage look like telephone poles sticking out of the ground. A broad base give a visual stability to a tree and Fuku-Bonsai excels in this most important area!
Next consider the lower trunk and the major lower branches. These too are important. Too often we see beautiful foliage and a nice top that sits on a spindly trunk without any character. If a tree has good rootage, lower trunk, and strong low branches, all things are possible. So in refinement, place emphasis on preserving these qualities. There are many ways to train a tree according to the kind of shape you desire.
|1. CREATING A LARGER BROAD CROWN. If you want to keep the height of your tree the same but want to create a wider broader crown, set your top shin point at the end of the woody section and the lower branch points outside of existing low branch points. Prune any and all top growth that grows beyond the lines and allow lower branches to keep growing outwards. A good rule is to prune the portion of the tree that is growing most vigorously. Keep the lines in mind and prune back to below the line. Until you become proficient, use the ruler to guide you.|
|2. CREATING A LOWER BROADER CROWN. This is a variation of the above technique in which pruning is based upon the actual length of the lowest branch. This variation is used extensively at Fuku-Bonsai to produce the strongest possible lower branches and stout trunks. It is relatively easy to raise the shin point to create a taller bonsai. When looking down on a tree, try to select three major lower branches facing out about 120° angles as this will create a well rounded tree. Build up 3 additional but shorter branches above and between the first three and keep these heavily pruned back.|
|3. CREATING A TALLER NARROWER CROWN. If you have well-developed roots and lower trunks, this is fairly simple. select the woody ends of the lowest branches and the highest shin point. Prune very aggressively to the connecting lines at appropriate points. If you're pruning larger branches, prune back a bit from the line to allow developing some branch taper as you finish off creating a taller tree. Generally the goal is to create a wide tree, but the principle is the same if you want a taller tree.|
|4. CREATING AN ULTRA LOW WIDE CROWN. Severe pruning will often result in an explosion of many new growth points including sometimes from the base of the roots! From time to time, we will greatly reduce the height of an older tree and create such wide crowns with very stout trunks. While this may seem high risk, it isn't if the trees are growing strongly. This technique is often used with extra large containers to obtain strongest growth and fastest development. Trees are heavily fertilized. Once the new shape is attained, it is potted into a shallow container and growth slows.|
|5. CREATING A MORE OPEN CROWN. Some customers prefer a taller tree with a more open crown rather than the stoutness associated with tropical banyans. Because of the well developed rootage and heavy trunks, it is often possible to remove several large heavy branches to create an elegant more open structure. This type of restyling should be done only after a lot of study as it is very easy to remove too many branches. To help visualize what the tree will look like with a branch removed, cover and wrap up the branch with a dish towel.|
|6. "CHANGING SHIN". Sometimes a major change in training strategy will greatly improve a tree and the shin point is shifted to a very different part of the tree. When this is done, it is preferable to remove ALL of the former "shin line" to avoid having conflicting themes. Using the principle of marking the ends of the main lowest branches, it is a simple mater to prune off old growth to readjust to the new styling. Trees retrained by changing shin are often outstanding!|
|7. REPOTTING AFTER A SHIN CHANGE. While it's sometimes appropriate to have a new slanting shape, at other times, it may be preferable to repot to bring the restyled tree to a more upright position with the new shin pointing up. This will give the tree the strongest growth. This often results in creating a more exciting new root buttressing.|
|8. ONE & TWO BRANCH STYLING! Before restyling any tree, always consider reducing the tree to just the first or second lowest branch. While this is often the most radical of all alternatives, it produces the largest proportional trunks and roots. In having a larger well developed root system, the plant will grow very vigorously into the desired new styling. Even if you select another styling design, in considering this most radical alternative, often other ideas become apparent. If you've studied the tree carefully over a period of time, you'll be able to proceed with confidence once you know you've fully explored all alternatives!|
Bonsai is a thinking man's game! There are really only three major parts: 1) the horticultural challenges that are dictated by the tree, 2) the training technique, and 3) creating the long-term design.
The horticultural challenges are very straightforward. If your tree is growing well, you're doing fine. As you become more of an expert in growing YOUR TREE IN YOUR ENVIRONMENT, you'll become more successful in training. But if you cannot grow a healthy tree, you will not be able to train it. Training bonsai places extra stress on a tree! DON'T TRAIN UNTIL YOUR TREE IS HEALTHY AND GROWING STRONGLY!
I grew up surrounded by potted plants and orchid greenhouses. Good friends, including the late Dr. Horace Clay, always emphasized the basics. While many thought the cause of their plant problems were exotic diseases that could be cured with sophisticated high-tech solutions, Horace found that problems usually were very simple to correct. Often they simply needed to learn how to apply fertilizer correctly. He always recommended one single fertilizer and taught how and when to use it.
Plants respond to proper care and cannot adjust to reasoning or a person's whims. Too often I am asked to help a person that begins: "I've followed your directions exactly but my plant is dying!" After a few emails, it's very obvious that the person doesn't have the faintest idea of the cultural information that was sent with the plant! Too often they have confidence in their reasoning and am very upset that the plant doesn't respond. Sometimes they are successful with one plant, give the same care to other plants, and can't figure out why the others aren't doing well. Bottom line: "Select plants that will grow well for you in your environment or change your environment to meet the needs of the plants!
Assuming your plants are healthy and growing vigorously, training techniques are relatively easy to learn. Like learning horticulture, stay with the basics and the best and easiest training technique is pruning. Anyone can learn to prune. If it's a small twig, a small pruning scissors may be okay. If you're reducing a 30' tall tree utilizing the radical one branch styling concept, you might want to use a chainsaw. But in either case, knowing where to cut is more important than how to cut or what tool to use.
So the most difficult factor is styling and refinement and each of us approach this in a different way. The late Haruo "Papa" Kaneshiro was the beloved "Father of Hawaii Tropical Bonsai." He shared what he knew and used very conservative bonsai techniques that developed small nice trees. But the trunks were a bit thin and it took many years of meticulous skill. When I was developing Reduction-Building techniques, Papa couldn't stand it. It was just too aggressive for him. But he loved the results and only found fault with the way the results were obtained! He was happy to take home plants to add to his collection and he did fine work to refine them.
If you study the finest masterpiece bonsai, you'll find that most began as outstanding collected stock the were dug from the mountains. The trees were already old when collected and the training of the foliage sections were done in a relatively few years. Our Reduction-Building techniques were patterned after the same concept that Nature used to create her masterpieces. They are the result of repeated mass reductions followed by vigorous growth. Each such sequence add a layer of character and results in exciting plant stock. As the tree moves into the refinement stages, pruning can be done either conservatively or can continue to aggressively add more layers of character.
As professionals, we take pride in creating trees with high potential for our customers to complete styling and refinement Both require pruning skills! To obtain an understanding from a different perspective go to the two Reduction-Building articles that trace the development of two trees over a 30-year period. *** Go to Reduction-Building I
