Well, last year the Oca grew, but yield and size left a bit to be desired.
So, inspired by some potato growers, I've decided to take a shot at growing Oca in a tyre set-up.



Not going to go into details on that here as most will know the theory, and I've done a comprehensive guide on the blog - link in sig.

However, I recon the extra heat from the tyre/rock combo should increase size and yield, and there is the insulation factor from the rubber, as wall as an option to add a glass or transparent cover to increase temp.
If the result is poor, I dont think it's worth the hassle to grow out here.

Its also known as New Zealand Yam, tastes like apple/carrot/citrus raw, or kinda nutty when roasted. Great with lamb or fish.

For advice on growing it, well worth visiting oca-testbed.blogspot.com.

One important note, it does not begin to tuber up until after the Autumn equinox, when the dark hours get longer than daylight hours.
