Bonsai From Seed: Essential Steps for Success - Full Lecture

 Source material: Nov 20, 2022

        Have you ever tried one of those bonsai-from-seed kits and nothing grew? Or maybe you had a few seeds grow but had no idea what the next steps were to transform your seedling into a bonsai! Growing a bonsai from scratch is an intoxicating idea for beginners, but it is also one of the hardest feats to accomplish. In this lecture, I explain the basics of seed collection, storage, and germination to help you optimize your success at waking seeds up. I also explained the steps necessary to shape seedlings over the years following germination which will help you build sizable trunks and tapering branches to create a convincing and stunning bonsai. You can also participate in the active learning questions from home by commenting below and listening in on the discussions and questions from the Columbus Bonsai Society (CBS) members who attended. I gave this lecture in November 2022 for the Columbus Bonsai Society. Join us at www.ColumbusBonsai.org

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.

The Cost of Sex

Source material: 2017, April-July

          In the course of my biology education, the cost of sex and reproduction to an organism has repeatedly come up across specialties—and plant sex is certainly no different. For mammals, females usually carry most of the energetic burden due to long gestation and lactation periods relative to other animals. However, sometimes males in the animal kingdom also pay a cost to pass on their genes. For example, a male walrus in "rut" undergoes a reproductively active period of a few months, where the walrus directs massive amounts of energy to its sole focus of reproducing and vocalizing for potential mates. During this period, male walruses can lose their coat of brown fur, have increased disease susceptibility, and their eyes start to turn red and bulge out as an odd indicator of systemic bodily neglect. There is also the famous example of a praying mantis male literally sacrificing itself to offer nutrients to the mom and in turn, increases the fitness of his offspring. The aptly named black widow spider undergoes a similar ritual.

          With such examples in mind, it should come at no surprise that all those flowers in last month's blog post, Spring at Elandan Gardens, have a cost to those trees too. The trees' hard-earned sugars and nutrients were spent in exchange for beauty, pollen generation, pollinator attraction, wind pollination (for less showy trees with cones, most maples, etc.), and seed maturation. For a healthy tree, these expenses are not a problem, but we may still have reason to intervene and choose whether to allow our bonsai to reproduce or not. I will demonstrate some examples of how one might acknowledge the energetic cost of plant reproduction and control it as a tool to speed development, increase health, or maintain the balance of vigor of your bonsai.
