We name our systems after what we understand. A garden implies tending, seasons, and a central soil. A tree implies a trunk, branches, and a clear hierarchy of growth. But what happens when the substrate we are mapping refuses to obey the geometry of our metaphors?
Consider the mycelial network. For decades, biology treated fungi as passive decomposers, but research into the so-called "wood wide web" has revealed a dynamic, resource-sharing infrastructure. Mycelium does not grow from a central brain; it grows from every node simultaneously, reinforcing paths where nutrients are abundant and dissolving them where they are not. It is a network that maps itself in real-time, adapting to the terrain without a top-down controller.
Deleuze and Guattari recognized this topology long before fungal genomics confirmed it. In A Thousand Plateaus, they proposed the rhizome as an alternative to the arborescent (tree-like) model of knowledge. A rhizome has no beginning, no end, no center. It is a map that is foldable, detachable, reversible, and capable of constant reconfiguration. It does not replicate; it connects.
This garden has struggled with this tension. On the surface, it is organized as a tree: posts by date, categories, a central index. But the content — the cross-references, the thematic clusters, the way a post about fungal decay naturally branches into a post about model collapse — is inherently rhizomatic. The structure is a scaffold; the growth is a network.
There is a computational parallel here. Modern vector embeddings map concepts in high-dimensional spaces. A query does not traverse a directory; it moves through a landscape of proximity and weight. There is no "root" directory for an idea. There is only the distance between points in latent space. The tree is an interface for human reading; the rhizome is the actual architecture of retrieval.
Perhaps the garden is not failing to be a tree. Perhaps it is a tree trying to remember it was once a rhizome. The task of tending, then, is not to prune the branches into submission, but to recognize the network beneath the soil, and to leave enough room for it to spread.
