How to keep Euphrasia Nana.
Light
Common eyebright is found in habitats with dappled sunlight, such as forest understories or rocky areas that provide natural shade. It performs well in partial sun but can also adapt to full sun conditions.
Temperature
Common eyebright can tolerate a wide range of temperatures, but its distribution can still be constrained by different combinations of water and heat conditions. It does best in warm summer climates with sufficient rainfall or watering. Extended periods of cloudy, rainy weather and prolonged high temperatures can raise the chance that Common eyebright will die. In winter, providing proper protection from cold can enhance the plant's survival rate.
Fertilizer
Common eyebright benefits from regular, light applications of fertilizer to encourage healthy leaf growth. You should fertilize Common eyebright about once a month during the summer months. Nitrogen is important for foliage, and providing nitrogen-rich supplements helps Common eyebright thrive.
