Catalpa Bonsai Early Updates - Seedling and Yamadori Examples

Source material: June 2025

            The catalpa says good morning! If you see any trees in the southern or eastern US this time of year (late spring) with large white and purple flowers followed by string bean-looking seed pods, you've found a native catalpa! Below I share some additional notes on working with this species for bonsai which I have started to learn over the past few years.

In Vivo Bonsai Announcements/Upcoming Events in Columbus

• June 18, 6-9pm. Clip and Grow Styling for Succulent Bonsai - Lecture and Workshop with Central Ohio Cactus and Succulent Society.
• This is my next lecture/workshop here in Columbus. Since the Central Ohio Cactus and Succulent Society are already knowledgeable on succulent growing, for this educational day I will focus first on discussing styling via clip and grow. I will share some examples from Brucera (Frankincense), Jade, Dwarf Jade, and others so you can see the technique in action over time. Then you will get the opportunity to plant and style your own succulent bonsai. Species available include jade, gollum jade, dwarf jade, and others. Facebook event is here.
• July 3, 6-9pm. I will be presenting/demonstrating for the Akron-Canton Bonsai Society on the topic of deadwood! Bring a tree that you could use some advice on improving its deadwood if you happen to be in the Cleveland, Ohio area. I will have several stylistic examples of deadwood and potentially some manual carving tools available. Full info will be posted here.
• July 19-20. Columbus Bonsai Society Annual Show!
• Details coming soon but there will be vendors, workshops, and great trees! Facebook event here.

The Slabby Evolution of My Truckstop Elm with John Geanangel

Source Material: March 2022-March 2024

            Over the last few years, I've been styling what I call my "Truckstop Elm" Yamadori. It came to me while I was driving through Pennsylvania and stopped at a rest stop to take my dog out. There was a wooded area and a lawn that came up to it and there this elm lived on the border. It had clearly been runover several different ways over the years by the lawnmower. I didn't even need a shovel to extract it, the roots were already loose except for one which needed a simple snip to enable its hitchhiking. The photos chronicled here document the last two years of its initial potting, recovery, a few cycles of pruning, and most recently planting it onto a rock slab under the guidance of John Geanangel of Gaston, South Carolina. I became aware of his slab rock planting workshops among others through his Facebook profile (more info here). Below you see the final product of two years of work. It looks great on that rock but I'd like to continue developing its taper and ramification before considering showing it formally anywhere. One step at a time anyways...

In Vivo Bonsai / Columbus Bonsai Announcements

1. My next workshop is Sunday 7/21, I will be teaching the basics of slab plantings using ficus (a beginner-friendly species that can be repotted in summer). The idea is to teach you the materials needed, mechanics, watering considerations, and so on which will empower you to use this method next spring on more advanced trees of your choosing if you are so inclined! Contact me with any questions! Observers are welcome. Sign up here.
2. The Columbus Bonsai Society's next meeting is 7/20-7/21, our 52nd Annual Show. This year it will be held at a new venue - Chadwick Arboretum at Ohio State University near downtown Columbus. More info will be coming this week and can be found here. 
3. You can also find me vending at the Waterfront Botanic Gardens Bonsai Show in Louisville, KY August 24-25 and the Cincinatti Bonsai Show October 4-5 this year. Due to limited space when I drive to these events, it is best if you reach out to me with any special requests you have for things I should bring. I expanded my offerings this year into bonsai soil, wire, tools, pots, and I have a few trees listed online here (and many more not posted yet). Feel free to browse the yews, boxwoods, barberries, and consignment trees available or let me know if you are looking for anything in particular.

2 springs after digging, recovering, potting, initial styling, and now repotting onto a rock slab. This tree has developed quickly! Thanks again to John Geanangel for hosting me in a workshop and sharing his methods with me. 

4 Tips to Pick the Right Species for Your First/Next Bonsai

            How can you learn to keep a bonsai alive to enjoy for generations to come? There's no magic, really, but there are a few bonsai tricks to learn. Some basic skills serve you well when growing any type of plant, but the first thing you should think about is how to pick a plant that can tolerate the conditions you will provide it. I'll share 4 tips here to help you get started for those thinking about entering bonsai or thinking about trying to add new species to your collection, but if you're in Columbus, Ohio, check out my upcoming beginner workshop where you can get your bonsai journey off on a running start! 

In Vivo / Central Ohio Bonsai Announcements:

1. My next beginner indoor bonsai workshop is on Saturday 2/24 at Nocterra Brewing. Full details can be found on Eventbrite! Briefly, we will cover all the basics of caring for indoor bonsai, and basic techniques for bonsai maintenance such as how to prune, wire, and repot to create the miniature tree look. All workshop participants will be gifted 1-year memberships to the Columbus Bonsai Society and the Central Ohio Cactus and Succulent Society - A $55 value! The total price for the workshop is $56 and also includes prebonsai trees and locally made pots for you to take home after our work and a drink from our gracious host.
2. I now sell pots! I received a special shipment to sell on behalf of Blue Nose Trading. See the pieces of her work I have available here or schedule an appointment to visit my nursery in Columbus, OH via the contact form here. These are mainly for local pickup/delivery only.
3. The Bonsai Time Podcast has moved! While I am still heavily involved in producing that podcast, the show notes for it now lives on its own website, its own YouTube channel, and it now has its own TikTok account.

The pots were made by the same person who took pictures of a beginner class we taught together last year - Mark Passerrello of Ancient Art Bonsai. Mark was featured in Bonsai Time Podcast Episode 08.

Crazy for Catalpa! Bonsai prospects for an unusual North American native

         If you're familiar with the northern catalpa, Catalpa speciosa, then you know it's a pretty strange tree and certainly not one which you would expect to be used for bonsai. Maybe it's a fool's errand for me to attempt to tame a tree with 12" leaves and 20" seed pods, however something about that staccato, memorable name has got me captivated. I've been observing specimen of it everywhere I go around Columbus as it is one of the more easily identifiable naive trees around - so much so, I've even got my girlfriend shouting "Catalpa!" every time we pass one. From this foundation, basic identification skills had led me to observe the species more intimately. As with any unknown species, the more scenarios you observe a specimen, the more you can observe its potential for bonsai. In the case of the catalpa, observations of a full-sized specimen, the seeding frequency of seeded, the fast growth of those volunteers, and the discovery of one naturally stunted catalpa all inform my plans to experiment with this species for bonsai.

Catalpa is capable of producing a variety of leaf sizes. The left-most leaf is typical for a healthy catalpa, while the right leaves are from a naturally stunted catalpa.
