How to keep Elymus Athericus.
Light
Sea couch is a sun-loving, perennial herbaceous plant that comes from open habitats and frequently prospers in meadows and grasslands. It favors full sun but can also tolerate partial sun.
Temperature
Sea couch can tolerate a wide range of temperatures, though its distribution may still be restricted by different combinations of moisture and heat. It performs best in warm summer climates with sufficient rainfall or irrigation. Extended periods of cloudy, rainy weather, as well as prolonged high temperatures, can raise the chance of Sea couch dying. In winter, adequate protection from cold can increase the plant's survival rate.
Fertilizer
Sea couch needs extra nutrients to encourage healthy new growth. In spring, spreading compost around the base of the plant will effectively supply the nutrition it requires. Fertilizing helps support vigorous growth and increases the plant’s ability to resist diseases and pests.
