Yarrow is known for its exceptional drought tolerance, making it well-suited to regions with minimal rainfall and well-drained soil. While it can withstand dry conditions, newly planted yarrow should be watered regularly to establish strong root systems. Once established, yarrow typically does not require frequent watering and is resistant to drought stress, making it an ideal choice for water-wise gardening.


Yarrow thrives in full sun and requires at least six hours of direct sunlight per day to reach its full potential. Adequate sunlight promotes vigorous growth, enhances flower production, and ensures the plant’s overall vitality. Yarrow can tolerate partial shade, but it may result in reduced flowering and less compact growth. When selecting a planting site for yarrow, prioritize locations with abundant sunshine and well-drained soil.


Yarrow is a relatively low-maintenance plant when it comes to fertilization. It does not typically require heavy feeding and can thrive in nutrient-poor soil. If the soil is particularly impoverished, a balanced, slow-release fertilizer can be applied in spring to support healthy growth and flowering. However, it is essential to avoid excessive fertilization, as it can lead to excessive foliage growth at the expense of flowers.


Yarrow prefers well-drained soil with a neutral to slightly alkaline pH. It can adapt to various soil types, including sandy, loamy, and rocky soils, as long as they are well-draining. To enhance soil drainage and fertility, organic matter, such as compost or aged manure, can be incorporated into the planting area. It is important to avoid waterlogged conditions, as yarrow is susceptible to root rot in excessively moist soil.


Pruning yarrow is a straightforward process that contributes to the plant’s overall health, appearance, and longevity. Proper pruning helps maintain a compact growth habit and encourages prolific flowering.


Regular deadheading, or the removal of faded flowers, promotes continuous blooming and prevents the formation of seeds. As the blooms begin to fade, simply trim the spent flower heads to encourage the production of new flowers. Deadheading also helps prevent self-seeding and maintains the aesthetic appeal of the plant throughout the growing season.


Yarrow benefits from occasional division, especially as the center of the plant becomes crowded and less productive. Divide mature yarrow plants every two to three years to rejuvenate growth and maintain their vigor. Carefully dig up the plant, separate the clumps into smaller sections, and replant the divisions in suitable locations. Division not only revitalizes established yarrow but also provides opportunities for propagation and expansion of yarrow in the garden.


Yarrow can be propagated through various methods, including division, seeds, and cuttings. Understanding these propagation techniques allows gardeners to multiply and share their yarrow plants effectively.


Division is a reliable method for propagating yarrow and is typically performed in early spring or early autumn. To divide yarrow, carefully dig up the established plant, ensuring that the root ball remains intact. Using a sharp, clean tool, separate the plant into smaller clumps, ensuring that each division has healthy roots and shoots. Replant the divisions in prepared soil, water them thoroughly, and monitor their growth as they establish themselves in their new environment.


Yarrow can also be propagated from seeds, offering an affordable and convenient means of expanding the plant population. Start yarrow seeds indoors, approximately six to eight weeks before the last frost date in the region. Sow the seeds in seed-starting trays with well-draining soil, lightly press them into the surface, and keep them consistently moist until germination occurs. Once the seedlings have developed several sets of true leaves, they can be transplanted into the garden or larger containers.


Propagation of yarrow through cuttings is a viable method for reproducing specific cultivars or ensuring genetic uniformity. Take 4- to 6-inch cuttings from healthy, non-flowering stems of yarrow, ensuring that each cutting has several leaf nodes. Remove the lower leaves, dip the cut end in rooting hormone if desired, and plant the cuttings in a moist, well-draining rooting medium. Place the cuttings in a warm, bright location and ensure adequate humidity to facilitate rooting. Once rooted, the cuttings can be transplanted into the garden or larger pots for further growth.

Container Popularity

Yarrow is well-suited for container cultivation, offering versatility, portability, and aesthetic appeal in various settings. By choosing the appropriate container and providing optimal growing conditions, yarrow can thrive in contained environments.

Container Selection

When growing yarrow in containers, it is essential to select pots or containers that provide ample space for root development and stability for the plant.

In addition, consider the size of the mature yarrow plant and select containers that accommodate its growth without becoming overcrowded.

Growing Medium

Select a well-draining potting mix that provides a balanced combination of moisture retention and aeration. Incorporate perlite, coarse sand, or vermiculite into the potting medium to enhance drainage and prevent the development of waterlogged conditions. A high-quality potting mix with added organic matter can promote healthy root development and overall plant vigor.


Container-grown yarrow requires vigilant attention to watering and soil moisture, as pots can dry out more quickly than garden soil. Monitor the moisture levels regularly and water the plant when the top inch of the soil feels dry to the touch. Avoid overwatering, as excessive soil moisture can lead to root rot and other complications. Additionally, containers may require repotting or refreshing of the potting mix every few years to ensure optimal growing conditions.

Common Diseases

Yarrow is generally resistant to most pests and diseases, but it may occasionally encounter certain issues that can compromise its health and appearance. Understanding the common diseases affecting yarrow is crucial for early detection and effective management.
