They planted the five-acre patch that had gone fallow. Silas had never seen seeds like these: small, dark, angry-looking, like pellets of black pepper. Lena walked the rows, broadcasting by hand, her rhythm old as sowing itself.
They waited two weeks. Then, on a nervous, overcast morning, they planted their brassicas again—the same variety that had failed before. Small, trembling seedlings.
Within a week, the mustard exploded. Not like a crop—like a conquest. The seedlings were aggressive, broad-leaved, a carpet of deep green that swallowed weeds whole. Within a month, the field was a sea of brilliant yellow flowers, humming with a fury of bees. It was beautiful, and it hurt Silas to mow it down at its peak.
“It’s a biofumigant,” Lena insisted, tapping the packet. “You plant it. Let it grow until it flowers. Then you mow it, till it under—while it’s still green. The glucosinolates release. It’s like tear gas for the nematodes. For the fungi. It cleans the soil.”
“Mustard,” she said, placing it on his kitchen table. The packet was plain, just a handwritten label: Caliente Rojo. Cover Crop.
The flail mower chewed the flowers into confetti. Then came the rototiller, churning the green wreckage into the topsoil. For three days, the field smelled like a horseradish factory—sharp, hot, stinging. Silas’s eyes watered just walking the perimeter.
“It’s working,” Lena whispered, sniffing the air like a wolf.
