Oca: Seedling progress

We’re up to 23 oca (Oxalis tuberosa) seedlings from my early August sowing of 60 seeds. The earliest are now putting out true leaves and starting to look like proper oca plants. As is usually the case with seedlings, growth has picked up considerably since they formed true leaves. We’re a month away from the […]

Most seeds have some dormancy and won’t grow until time has passed or specific conditions of temperature and humidity are reached. I separated 60 seeds into three groups of 20. I soaked each […]

Six to eight inch cuttings are just right I wrote a couple weeks ago that I was going to try a few experiments to determine how to harvest the most oca (Oxalis tuberosa) seeds with the lowest losses (the two kind of go hand in hand). The verdict is in: indoor cuttings have provided significantly […]

Oca: 1000

Climate I have not grown […]
