Arrowroot tubers – Maranta arundinacea

Though some sources report that growing arrowroot requires shade, I’ve had it do well in almost full sun along the path in the center of my food forest.

I’ve grown it in full shade as well, though that plant was less productive. Half-sun seems to be the sweet spot. If you get good rainfall and have decent soil, the yields increase. My arrowroot plants are fed with nothing but rotting wood chip mulch from the power company tree trimmers and that’s been enough for them to produce decent yields of roots. I pulled one from a rich and moist garden bed and got about 4 times the roots from it as from the one in the video above. Location, location, location!

That said, they really are a low-care perennial.

When to Harvest Arrowroot

When you’re growing arrowroot and it starts to die in the fall, don’t fear. It’s just going into dormancy. They’ll freeze to the ground in winter and come back again in the spring, much like ginger.
