Care Instructions
Eryngium planum thrives in full sun and prefers moderate temperatures. It requires well-drained soil and should be watered sparingly, allowing the soil to dry out between waterings. The plant can tolerate average humidity levels and does not require high humidity.Soil
Eryngium planum prefers well-drained loamy soil. It can tolerate poor soil conditions but thrives best in soil that is not overly rich in nutrients. Good drainage is essential to prevent root rot.Fertilizer
Fertilize Eryngium planum with a balanced fertilizer such as 5-10-10 in the early spring. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.Repotting
Repot Eryngium planum in the early spring if it has outgrown its container. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Gently remove the plant from its old pot, shake off excess soil, and place it in the new pot with fresh soil.Propagation
Eryngium planum can be propagated by seeds or division. Sow seeds in the spring or fall, or divide mature plants in the spring. Ensure that each division has a portion of the root system and replant immediately.Pruning
Prune Eryngium planum in the late fall or early spring to remove dead or damaged foliage. This helps to maintain the plant's shape and encourages healthy new growth. Deadheading spent flowers can also promote additional blooming.Toxicity
Eryngium planum is not known to be toxic to pets or humans. However, it is always advisable to handle plants with care and wash hands after gardening.Additional
Eryngium planum is a great addition to pollinator gardens as it attracts bees and butterflies. It is also deer-resistant and can be used in dried flower arrangements due to its long-lasting blooms.REVOLUTIONIZE YOUR PLANT CARE
