Chapter 15 — Delve and Crumb and the Kitchen Nobody Sees

Crumb the composter and Delve the root-tender worked at opposite ends of the same darkness, and a young earthworm named Squiggle couldn’t see why they were always mentioned together. “You do the rotting,” Squiggle said to Crumb, “and you do the roots,” to Delve. “Those are two different jobs.” Crumb and Delve traded a knowing look. “They’re two halves of one job,” said Crumb. “The garden’s kitchen. Let us show you how it runs.”

Crumb went first, plunging into her warm heap of leaves and scraps. “I’m the cook. When anything in the garden dies — a leaf, a stalk, a fallen fruit — it lands in my kitchen, and the shredders and fungi and bacteria break it all the way down into humus: dark, rich, and packed with the exact minerals a plant needs. That’s the decomposition half. I take yesterday’s dead things and turn them back into food.” She held up a crumbling handful. “But here’s my problem, Squiggle: I can cook a feast all day long… and I have no mouth to feed it to. The food just sits here in the soil, ready, waiting. On my own, I’m a kitchen with no diners.”

“And that,” said Delve, surfacing dirt-nosed from below, “is where I come in. I’m the eater — or rather, the plant’s eater. My roots thread through Crumb’s finished soil, and the root hairs drink the dissolved minerals she cooked, pulling them up into the plant to build new leaves and stems and fruit. That’s the uptake half.” She paused. “But here’s my problem: I can drink all day, and I’d drain the soil empty in a season — roots take and take. On my own, I’m a diner at a table that never gets refilled. I’d starve the ground bare.”

Squiggle’s eyes went wide as it clicked. “So Crumb makes food but can’t use it — and Delve uses food but can’t make it. Each of you would fail alone!” “Now you’ve got it,” said Crumb. “I refill the table Delve empties.” “And I eat the feast Crumb would otherwise leave to rot,” said Delve. “Round and round: a leaf dies, I cook it into soil-food, Delve’s roots drink it, the plant grows new leaves, those leaves die and come back to my kitchen. It’s not a straight line from alive to dead. It’s a cycle — the same minerals going around and around, cook to eater to plant to cook again, forever.”

So the three of them followed one mineral all the way around that afternoon — out of a rotting autumn leaf, through Crumb’s kitchen into rich humus, up through Delve’s root hairs into a bright new spring leaf, and (Squiggle imagined) eventually back down to the kitchen when that leaf, too, would fall. “This is why we’re never mentioned apart,” Delve told the worm. “Decomposing without roots to drink it is a feast nobody eats. Roots without decomposers to refill the soil is a diner that starves the table bare. The garden only keeps going because the cook and the eater are two ends of one loop.” “One cooks,” said Crumb. “One eats,” said Delve. “And neither of us works alone.”
