How to keep Euphrasia Officinalis.
Light
Eyebright comes from habitats with dappled sunlight, such as forest understories or rocky sites that provide natural shade. It does best in partial sun but can also tolerate full sun conditions.
Temperature
Eyebright can tolerate a broad range of temperatures, but its distribution may still be restricted by different combinations of moisture and heat. It grows best in warm summer climates with adequate rainfall or watering. Extended periods of cloudy, rainy weather, as well as prolonged high temperatures, can raise the chance of Eyebright dying. In winter, proper protection from cold can enhance the plant's survival rate.
Fertilizer
Eyebright benefits from regular, dilute applications of fertilizer to encourage healthy leaf development. You should feed Eyebright about once a month during the summer. Nitrogen is essential for foliage, and providing nitrogen-rich sources helps Eyebright thrive.
