Achillea ptarmica, commonly known as Sneezewort or Sneezeweed, is a perennial plant in the Asteraceae family. It is native to Europe and Asia and is known for its clusters of small, white, button-like flowers. The plant thrives in temperate climates and is often found in meadows, grasslands, and along riverbanks. It has a dormancy period during the winter months.
Achillea ptarmica is relatively easy to care for. It prefers full sun and moderate temperatures. Water the plant when the soil partially dries out, and ensure it has good air circulation. It can tolerate a range of humidity levels but prefers moderate humidity. Regular deadheading of spent flowers will encourage more blooms.
土壌
Achillea ptarmica prefers well-draining loamy soil. It can tolerate a range of soil types but thrives best in soil that is not too rich in nutrients. Ensure the soil has good drainage to prevent waterlogging, which can lead to root rot.
肥料
Fertilize Achillea ptarmica with a balanced fertilizer, such as 5-10-10, once in the spring. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
植え替え
Repot Achillea ptarmica every 2-3 years or when it becomes root-bound. 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.
伝搬
Achillea ptarmica can be propagated by division or from seeds. The best time to divide the plant is in the spring or early fall. Dig up the plant, separate the clumps, and replant them in well-prepared soil. Seeds can be sown in the spring after the last frost.
剪定
Prune Achillea ptarmica in the late fall or early spring to remove dead or damaged stems. Regular deadheading of spent flowers will encourage more blooms and keep the plant looking tidy.
毒性
Achillea ptarmica is not toxic to pets or humans. However, some people may experience skin irritation when handling the plant, so it is advisable to wear gloves.
追加
Achillea ptarmica is a great addition to any garden due to its long blooming period and low maintenance requirements. It is also attractive to pollinators such as bees and butterflies, making it beneficial for the ecosystem.
