The Message the Root Sends

Before the plant arrives, something else does. Not a root — not yet. A chemical. A whisper dissolved in water, pressed out through the very tip of the root as it pushes into the dark. You can't see it. You can't smell it. But the soil is already reading it. Billions of bacteria, coiled and waiting, feel the signal arrive and begin to move. Some rush toward it. Some begin to change shape. The root hasn't touched them yet, and they are already preparing a welcome. This is what the plant sends ahead of itself: not scouts, not feelers, but a language. A vocabulary of sugars, acids, and proteins, each word meaning something different to a different creature in the dark. Some words say: *come and feed here, and in return, unlock the iron I cannot reach*. Some say: *I am a stranger, hold back*. Some say: *my neighbour is sick — prepare*. The plant above ground looks still, looks silent. Down here, it is talking constantly, and the soil is talking back. We have been farming for ten thousand years. We learned the words existed about forty. Every field we have ever planted, every crop we have ever fed a city with, was already in the middle of a conversation we didn't know was happening.
