> Cutting or girdling trees with power or manual saws are effective at preventing seed production, but an herbicide treatment is necessary following cutting since Paulownia readily re-sprouts. Hand pulling may be effective for young seedlings. Plants should be pulled as soon as they are large enough to grasp. Seedlings are best pulled after a rain when the soil is loose. The entire root must be removed since broken fragments may re-sprout. Cutting or pulling is the preferred mechanical treatments of the Paulownia tormentosa; do not use fire because this species is able to survive fire and then quickly proliferates and out-competes native tree species post-fire.
