oca - how to hill up?

growingdreams(z9 SF Bay Area)June 2, 2012

I'm trying oca (oxalis tuberosa) for the first time this year. I've seen advice that they will produce more if they are hilled up. But, I haven't found any specifics about how to do that.

There's lots of information about hilling up potatoes, but the oca plants have a very different structure with multiple stems and many small leaves at different heights. If I put soil around them I will be burying many of the leaves. Is that OK?

Thanks for any advice!

I wouldn't bury the foliage. Try using something like sand that will sift or filter through the foliage. I would do it gradually, over the course of a few weeks so it doesn't smother the plant. They're a lot more delicate than potatoes. I tried growing it, but it doesn't make tubers here before it freezes.
