How to keep Oxalis Polyphylla.
Light
Finger wood sorrel naturally grows in habitats like forest understories or rocky areas where it is exposed to natural shade. It favors partial sun but can tolerate full sun or full shade, showing its adaptable and hardy nature.
Water
Finger wood sorrel thrives with moderate watering. Avoid overwatering, ensuring the soil doesn't become soggy. Water the plant when the top inch of soil feels dry, and make sure the top two inches stay moist after watering. While rainwater is ideal, you can also use warm tap water, provided it's not hard.
Temperature
Finger wood sorrel can tolerate a wide range of temperatures, but its distribution may still be restricted by various combinations of moisture and heat. It performs best in warm summer climates with sufficient rainfall or watering. Extended periods of cloudy, rainy weather or prolonged high temperatures can increase the risk of Finger wood sorrel dying. In winter, adequate protection from cold can raise the plant’s survival rate.
Fertilizer
Typically, one fertilizer application in spring is enough for Finger wood sorrel, though repeated feedings can increase growth. Apply fertilizer every month to a month and a half. Fertilizing improves the leaves' appearance and function, helping maintain even color and a healthy texture. It also promotes root development and nutrient uptake, supporting the plant's long-term health.
Pruning
Finger wood sorrel has delicate, finger-like foliage that benefits from pruning in early spring to promote growth. To maintain its shape, carefully remove dead leaves and trim overgrown stems, being cautious not to over-prune, as this can affect blooming. Always use clean, sharp tools to prevent infection.
