How to keep Centaurea Ragusina.
Light
Silver Knapweed is a sun-loving herbaceous perennial that comes from open habitats and commonly grows in meadows and grasslands. It favors full sun but can also tolerate partial sun conditions.
Temperature
Silver Knapweed can tolerate a wide range of temperatures, yet its distribution may still be restricted by different combinations of moisture and heat. It does best in warm summer conditions with sufficient rainfall or watering. Extended stretches of cloudy, rainy weather and prolonged high temperatures can increase the probability of Silver Knapweed dying. In winter, providing adequate protection from the cold can boost the plant's survival rate.
Fertilizer
Silver Knapweed should be fertilized mainly in early spring, when its flowers are beginning to form. Using the appropriate fertilizer promotes better blooms and helps Silver Knapweed produce attractive flowers. Fertilizing in early spring helps ensure excellent flowering throughout the season and provides energy for periods of dormant growth.
