How to keep Polygala Californica.
Light
California milkwort occurs naturally in habitats such as forest understories and rocky areas, where it experiences natural shade. It prefers partial sun but can tolerate full sun or full shade, demonstrating its versatile and hardy nature.
Temperature
California milkwort can tolerate a wide range of temperatures, though different combinations of moisture and heat can still limit where it occurs. It does best in warm summer conditions with sufficient rainfall or supplemental watering. Long periods of cloudy, rainy weather, as well as extended high temperatures, increase the risk of California milkwort dying. In winter, adequate protection from cold improves the plant's chances of survival.
Fertilizer
One fertilizer application in spring is generally enough for California milkwort, though repeated feedings can enhance growth. Apply fertilizer roughly every month to six weeks. Fertilization improves the leaves' appearance and function, helping maintain even color and a healthy texture. It also promotes root development and nutrient uptake for the plant's long-term health.
