Repotting Scenarios for a Shohin Privet and Intro to Bonsai Soil

Source Material: March 02, 2023

             Welcome back bonsai enthusiasts, today I share a short article focused on a recent repot which illustrates some larger questions we must ask for our trees to look their best. Where should I position my tree in the pot? To the center? To the left? To the right? How do I want the nebari/root flare to look given the options the tree provides? Read on for a closer look at the unique challenges and character of this tree, think through what you would have done if it was your tree, and feel free to share those ideas in the comments below.

Refining the 2-In-1 Step Method for Kintsugi Ceramic Repair

        Last time I gave y’all a thorough review of 6 different kintsugi methods you can choose from based on the needs of your pot-mending situation. After completing this review, out of respect for my current situation as a graduate student with limited time and funds, I opted to try one of the simplest methods - the "2-in-1 Step Method: Oozing Colored Epoxy". As I previously described, this method requires the least supplies, hands-on steps, and wait time while providing a durable end product. Because this method had concerns regarding control of the aesthetic quality, my next question was whether these limitations could be improved upon. Hence, today's article covers several trial pots I repaired with this method to observe and tweak the 2-in-1 Step technique. My results from the final pot I repaired (see below) advance the 2-in-1 Step Method as it demonstrates the ability to use this method to cleanly fill large missing pieces in some circumstances, which has not previously been reported. Combined with the careful application of the colored epoxy, this technique may now be closer to the quality associated with the more complicated kintsugi repair techniques.

        My recommendations for an improved 2-in-1 Step protocol can be found at the end of this article.

The result of my final kintsugi repair using the 2-in-1 Step Method: Oozing Colored Epoxy.
This piece had a large missing piece and some small gaps from smaller missing pieces which made it extra challenging for this technique.

Broken Bonsai Pot? No Problem! Modern Methods for Ceramic Repair Through Kintsugi

           Whether from poor packaging or handling during shipping, a strong wind, a pet-related accident, or just our own clumsiness, everyone in bonsai eventually has to deal with the frustration of a broken bonsai pot. If you found this article because this recently happened to you, don't despair. You do have options. You could repair the pot so the cracks from its catastrophe are barely visible, but in the esoteric world of bonsai aesthetics, generations of Japanese ceramics before us have developed a more artistic way to mend broken pots - this is the process known as kintsugi. 

        This article began from my own research into methods of kintsugi repair so I could repair one of my broken pots.  Like in other areas of bonsai, there is a centuries-old, established, traditional technique but there are also more modern methods that can make the process of mending pots faster, simpler, and cheaper. The objective of this article is straightforward - find step-by-step information that is doable for an amateur (like me), and then narrow down potential methods by expected durability, quality of end product, time to complete the repair, cost of materials, and convenience to locate said materials. To evaluate this list of considerations, I summarized the pros and cons of each method according to my findings and interviews with people who have tried each technique (See the summary table at the end for the short version). Finally, I modified the winning kintsugi repair protocol for use on my pot and I will share that process & result next time.

There are 3 main types of kintsugi repair - piece, crack, or joint-call. Of the 3 types, the joint-call repair is the rarest and not commonly seen in bonsai displays. Source

A Case Study for Applying the Water and Sugar Equations - Repotting the Risky Rose

Source material: 3/19/2021

            Hola bonsai amigos! Today is a great day because not only does your friendly neighborhood microbiologist (me!) receive his second Covid vaccine dose, but my immunized arms also come bearing another present to the bonsai community. As spring continues to march on, so too does the blog's coverage of my giant rosebush bonsai - this time the rose's latest repot reveals two fundamental equations of life to consider when manipulating bonsai or any plant.

            The "Risky Rose" was the second major repot I did this year; returning readers will recall from last week's post that this operation involved another of the largest trees in my collection - a yardadori/landscape origin rosebush turned bonsai. As discussed in the previous post, now that the tree has recovered several years after its initial transplanting endured a cross-country move and survived its first Ohio winter, our rose has definitely earned renewed attention this year. For now, I'm calling it the "Risky Rose" because it needed severe root reduction in order to change its planting angle and lift the upper half of the trunk out of the pot. Read on to understand the motivations behind this bold action, including what steps were taken to ensure this radical root reduction could be done safely.

            As with my last repotting post, "Repotting The Monster Mulberry - Revisiting the Basics", this repot was done with the help of my friend in the Columbus Bonsai Society, Kevin. Thanks, Kevin!

Origins of the Risky Rose & Steps for Transplant Recovery

 Source material: 2/09/2018

            As the weather continues to warm up and frosts become rarer here in Ohio, repotting season is on its tail end - if you're not already finished with it. I'm hoping to squeeze in my last few this week and also plan ahead for future bonsai by sowing my newest batch of seeds. In the spirit of finishing the repotting season, I was also planning to post the second major repot I did this year - once which involves substantial risk and reward. For now, that's all you'll get about it because, in the spirit of breaking my habit of writing overly long articles, today we have to first take a trip back in time and discuss the history of my gargantuan rosebush landscape-origin/yardadori prebonsai. It has perhaps the largest trunk rose I've seen in the bonsai world (not that they're a common bonsai subject to begin with!).

Germination, Taproot Removal, and Trunk Training - Oh My!

         As I've said before, there is a widespread, primal appeal in watching a seed sprout firsthand. The bonsai community can and should harness this craze for bonsai seeds by informing beginners rather than shaming them for not starting with more established prebonsai material. I hope that through my comprehensive Bonsai-From-Seed Guide, more of you will readers become disciples of our bonsai hobby and more of you will be successful at creating beautiful trees you can enjoy for decades to come.
          Last month in my serial Bonsai-From-Seed Guide, I already discussed some basic knowledge about the pros and cons of alternative ways to start a bonsai tree and bonsai seed myths which will hinder your seedling's progress if you aren't armed with the correct knowledge. This week, I'm going to start exposing the step by step, year-by-year methods you will need to employ as you watch your seeds sprout and grow. The transformation of your seeds into the bonsai of your dream won't happen just by waiting, it happens with because of your guiding hands (but yes, also with lots of waiting)!

Bonsai Seed Myths

          For people new to the art of bonsai, the idea of growing your own bonsai tree from seed is often irresistible. In theory, growing a bonsai from seed can be a rewarding journey that allows you to give birth to your own ideal image of what a bonsai should be, but unfortunately, in practice, seed-growing is a journey which is fraught with frustration for the vast majority of beginners. It has been said that it takes 10 years of experience in bonsai before you understand how to grow from seed well. I share this not to discourage you, but to brace you for the challenge ahead. If you're a new reader, I would encourage you to check out the first post in this growing from seed series, "The Root of All Bonsai." In that previous post, we talked about the various alternative ways to start your bonsai and the advantages and disadvantages of each method. However, if you are dead-set on growing from seed, you're in luck! Drawing on my own 15 years of bonsai experience and the 60+ years of experience of my bonsai teacher Dan Robinson, today we're going to cut through the BS and dispel common myths about growing bonsai from seed before we proceed to analyze the essential concepts that will help you realize your bonsai-from-seed dreams in the subsequent weeks. 

         If you're looking to buy seeds for bonsai - full disclosure - I am writing this series with the intent to sell my own seeds for growing bonsai (see here). At the risk of sounding too sales-pitchy, I am sending an exclusive hard-copy version of this blog series to all my customers. The hard-copy guide will simply guide you through the complicated 10+year challenge of growing bonsai from seed. If you can't wait for our weekly release of future blog articles in this series, you will receive the full guide right away with your purchase of seeds. Thank you in advance for supporting my bonsai work!

The Root of All Bonsai

          Many people don't know this but bonsai are actually made by magical, elven wizards disguised as humans. The best of these wizards channel the universe's energy into their green thumbs to create unbelievable works of art and captures the essence of a century-old tree into one small pot. Although millions of people around the world appreciate the art of bonsai, the methods of these bonsai wizards are somehow a total mystery to outsiders. Luckily, with dedication (and a little time reading my blog), you can learn their secret methods too.
          To illuminate these magical methods for creating bonsai, I'm excited to announce that today's post is the first from my five-part "How to Grow Bonsai From Seed" series (yes, this is what I've been keeping myself busy in quarantine!). Before we can even discuss how to grow from seed, it is only logical to discuss alternative ways to jumpstart your bonsai addiction, as growing from seed might not be suitable for everyone. Each source of prebonsai material has its own advantages and disadvantages, and each will challenge you to build your bonsai skills differently.

         If you're looking to buy seeds for bonsai - full disclosure - I am writing this series with the intent to sell my own seeds for growing bonsai (see here). I plan to send a hard copy guide to everyone who buys seeds from me and supports my work in bonsai. As I'm still drafting the final parts of this series, sales will probably not open until next week when I publish the next article in the sequence. Stay tuned! Even if you collect your own seeds, I hope this series will be a widely useful resource to all!

Here I am with one of my first collected trees. Of course, some bonsai owe their origins to natural environments! I estimated the age of this pine at about 30 years. Whitebark pines retain their needles for 3 years, so I was able to count using bud scars on the branch for this estimate. If you start humbly like this, collecting from wild, legal places can be one way to accumulate prebonsai trees.

When to Repot

Source Material: March 2020

          It is crucial to prune roots in their optimal window because if roots are pruned at the wrong time, this is one of the easiest ways to kill your bonsai (aside from simple watering neglect). The repotting season also is a vague window that changes from year to year based on the weather, adding to the risk of confusion for beginners and tree death. For the bonsai beginners out there, after today you'll be able to repot with much more confidence that your tree will make a healthy recovery. If you're already a bonsai expert, I put some pretty bonsai pictures in that I think you'll find worth scrolling for either way.
