Growing Guide: Arrowroot
Growing Tips
(Also known as: Arrowroot, West Indian Arrowroot, Obedience Plant, Maranta arundinacea*)*
Arrowroot grows best in full sun to part shade, rich, well-draining soil, and consistently moist, humid conditions. It can tolerate higher light in cooler temperatures, but should never be allowed to completely dry out. Avoid dense clay or very sandy soil, which can stunt growth. Feed during the growing season and protect from frost. Our Arrowroot plants are propagated by root division and typically need 1–2 growing seasons before harvest. For the best starch production, wait 10–12 months of humid weather, harvesting when the leaves begin to fall and the roots have become thick with starch.
