Oxalis flava grows in full sun or light shade exposures and in hot climates. They do not resist temperatures below 5 ºC (41 ºF). They prefer sandy soils with a little organic matter, for which a commercial preparation for cacti and succulents or a well-drained loam substrate can be used. Water moderately, waiting until the substrate has completely dried. Fertilize with mineral cactus fertilizer (or low nitrogen) once in spring and again in summer. They do not need pruning but their expansion must be monitored so that they do not become invasive. They are quite resistant to the usual pests and diseases. They are propagated from seeds sown in spring; They can be obtained from the fruits in capsule form. |
