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 […]
On August 7th, I started a quick and dirty experiment to see if any of my oca (Oxalis tuberosa) seeds would germinate. 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 […]
Today, my oca (Oxalis tuberosa) seed count stands at 1,022 for the year, which means that I have achieved my goal, with three or possibly four months left before the first frost. I have 123 pods maturing on cuttings indoors, which should yield about 900 more seeds by the averages and more than that bagged […]
I’ve had pretty good luck this year getting oca (Oxalis tuberosa) to flower and set seed. I’m growing enough plants to start to perceive some patterns regarding flowering. This information may be helpful to prospective oca breeders, but could also be misleading, based on such a limited period of time. Climate I have not grown […]
