Achillea tomentosa, commonly known as Woolly Yarrow, is a perennial herb in the Asteraceae family. Native to Europe, it is known for its woolly, gray-green foliage and bright yellow flower clusters. It thrives in dry, sunny habitats and is often used in rock gardens and borders. The plant undergoes a dormancy period during the winter months.
Achillea tomentosa is relatively easy to care for. It prefers full sun and can tolerate dry conditions. Moderate temperatures and low humidity are ideal. Water sparingly, allowing the soil to dry out between waterings. This plant is well-suited for outdoor growth and does not thrive indoors.
土壌
Achillea tomentosa prefers well-draining soil, such as loam. It can tolerate poor soil conditions but thrives best in moderately nutrient-rich soil. Ensure good drainage to prevent root rot.
肥料
Fertilize Achillea tomentosa with a balanced fertilizer, such as 5-10-10, once in the spring. Avoid over-fertilizing, as this can lead to weak growth and fewer flowers.
植え替え
Repotting is generally not necessary for Achillea tomentosa, as it is typically grown outdoors. However, if grown in a container, repot every 2-3 years to refresh the soil and provide more space for root growth.
伝搬
Achillea tomentosa can be propagated by division or from seed. Divide the plant in early spring or fall, ensuring each division has a healthy root system. Seeds can be sown in the spring after the last frost.
剪定
Pruning is beneficial for Achillea tomentosa. Deadhead spent flowers to encourage more blooms and cut back the plant in late fall to maintain its shape and health.
毒性
Achillea tomentosa is not toxic to pets or humans. It is safe to grow in gardens where pets and children are present.
