| Hey Raymondo. I live in southern Tassie and have grown oca before. They give us amazing yields, and I have not had trouble with weedyness any more than potatoes... nowhere like Jerusalem artichokes... Keep in mind that many oca cultivars are daylength dependent and will not produce well close to the equator. That said, the area they come from (Ecuador, Peru) sits spot on the equator, so cultivars that are daylength neutral might be around in Australia. I hope they work well for you as they do for me. I am now expanding and will probably grow several different cultivars in the future. I can't get enough of them and have substituted part of my potato patch for oca, which I eat raw, roasted, baked, barbecued, or any way you like.
A tremendously versatile vegetable. Cheers! Manuel. |
