Experimental studies demonstrate that cutting or burning above-ground biomass without removing or destroying the root crown results in rapid resprouting. Within 2–4 weeks, dormant buds activate, producing new vines that can grow up to 30 cm per day. The crown’s deep placement (often 10–30 cm below surface) protects it from mild fires and frost.
In the popular imagination, kudzu is a creature of the vertical. It is the "vine that ate the South," a leafy green tsunami that drapes over pine trees, swallows abandoned barns, and chokes the life out of telephone poles. We see its aggressive ascent, its relentless reach toward the sun. But this aerial spectacle is merely a performance; the true engine of the invasion lies inches below the soil surface.
The kudzu root crown is a highly specialized, resilient structure that underpins the species’ invasive success. Its large carbohydrate reserves, abundant dormant buds, and ability to regenerate from fragments make it the primary target for any long-term management plan. Future research should focus on crown-specific biocontrol agents and carbohydrate depletion dynamics.
