DETAILS

Care Instructions

Yarrow is a hardy plant that thrives in full sun and can tolerate a range of temperatures, though it prefers moderate climates. It requires minimal watering once established and can handle dry conditions well. Yarrow does best in well-drained soil and can adapt to various soil types. It is relatively low-maintenance and can be grown outdoors in garden beds or borders.

Soil

Yarrow prefers well-drained soil and can thrive in loamy soil. It is adaptable to different soil types, including sandy and clay soils, as long as there is good drainage. The soil should be allowed to dry out between waterings to prevent root rot.

Fertilizer

Yarrow does not require heavy fertilization. A balanced fertilizer with a nutrient composition of 5-10-10 can be applied in the spring to promote healthy growth. Over-fertilizing should be avoided as it can lead to weak, leggy growth.

Repotting

Yarrow can be repotted if necessary, though it is typically grown outdoors. If grown in containers, repotting should be done in the spring when the plant shows new growth. Use a well-draining potting mix and ensure the new container has adequate drainage holes.

Propagation

Yarrow can be propagated by division or from seed. Division is best done in the spring or fall by separating the plant into smaller clumps and replanting them. Seeds can be sown in the spring after the last frost. Ensure the soil is kept moist until the seeds germinate.

Pruning

Pruning yarrow helps maintain its shape and encourages more blooms. Deadheading spent flowers will promote continuous blooming throughout the growing season. In late fall, the plant can be cut back to the ground to prepare for winter dormancy.

Toxicity

Yarrow is generally non-toxic to pets and humans. However, some individuals may experience skin irritation or allergic reactions upon contact with the plant. It is always best to handle the plant with care and wash hands after gardening.

Additional

Yarrow is known for its medicinal properties and has been used traditionally to treat wounds, reduce inflammation, and alleviate digestive issues. It is also a valuable plant in the garden for attracting pollinators and beneficial insects, making it a great companion plant.
