Finding the Bonsai Within
Move beyond the nursery shelf and learn to identify the hidden 'bones' of a future masterpiece. This course teaches you to see past the foliage to find the trunk, roots, and species that will thrive under your care.
Like Duolingo, but for Finding the Bonsai Within. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through The Eye for Potential and Matching Species to Vision. It assumes you already know the basics.

Key ideas in Finding the Bonsai Within
- Trunk girth and root flare take decades to develop and cannot be easily faked
- Radial spread suggests a tree has been stable and growing in place for a long time
- Branches can be regrown or grafted in a few seasons to fix a poor canopy
- Visible surface roots create a sense of 'buttressing' seen in mature specimen trees
- Prioritizing the nebari over more easily changed features when selecting material
- The relationship between radial root spread and the illusion of age
- Nursery trees are often buried too deep
- Prioritizing nebari over branches
- The root collar determines the front
- Crossing roots create girdling
- Radial spread and age
- Roots growing back toward the trunk
- Bar roots create a flat look
- A wide base requires a shorter, more powerful 'sumo' style to look proportional
- Identifying structural root flaws that require immediate correction or rejection
- The ratio of the base width to the height determines the tree's perceived majesty
