full sun. Although oca can tolerate some drought, best yields are
achieved with plenty of water. Oca will do better in partial shade
where temperatures frequently exceed 80 degrees F. With some shade, oca
may be able to tolerate temperatures up to 100F, at least for short
periods of time. Low spots, protected from wind, that stay damp but
don’t pool are particularly good places to grow oca. Almost any plot of

little walking space in between. 24″ between rows will form a dense,
