Essential Steps to Grow Yarrow

Discover the essential steps to successfully grow yarrow in your garden. From selecting the perfect location to nurturing the plants, these key guidelines will help you cultivate this versatile herb with ease.

1. Find the Perfect Location:

Yarrow thrives in full sun, so choose a spot in your garden that receives at least six hours of direct sunlight each day. Yarrow plants appreciate the warmth and light, which contributes to robust growth and abundant blooms.

Additionally, yarrow prefers well-drained soil, so make sure the chosen area doesn’t retain excessive moisture. Sandy or loamy soil with a slightly alkaline pH around 6.0 to 7.5 works best for this resilient herb.

2. Prepare the Soil:

Before planting yarrow, it’s essential to prepare the soil properly. Start by removing any weeds, rocks, or debris from the planting area. Loosen the soil with a garden fork or tiller to a depth of around 8 to 10 inches.

This helps create a loose and friable texture, allowing the roots to penetrate easily. Incorporate organic matter, such as compost or aged manure, into the soil to improve fertility and drainage. This will create a favorable environment for yarrow’s root system to establish and flourish.

3. Start with Seeds or Transplants:

Yarrow can be grown from both seeds and transplants, giving you flexibility in how you begin your gardening journey. If starting from seeds, sow them directly in the prepared soil after the danger of frost has passed. Lightly cover the seeds with a thin layer of soil, as yarrow seeds require some light for germination.

Keep the soil consistently moist until germination, which usually takes around 14 to 21 days. If you prefer a head start, you can also purchase young yarrow plants from a nursery and transplant them into your garden. Transplants are a convenient option if you’re eager to see immediate results.

4. Watering and Maintenance:

Once established, yarrow is quite drought-tolerant and requires minimal watering. However, during the initial growth stages, it’s crucial to provide adequate moisture for the plants to establish strong root systems.

Water the plants deeply but infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot and other issues, so it’s best to err on the side of underwatering. As for maintenance, yarrow is generally low-maintenance.

Remove spent blooms regularly to encourage continuous flowering and prevent self-seeding. Trimming back any leggy stems or dead foliage can also improve the plant’s overall appearance.

5. Fertilize Sparingly:

Yarrow doesn’t demand heavy feeding, as it is adapted to thrive in nutrient-deficient soils. However, a light application of balanced fertilizer in early spring can give your plants an extra boost. Use a slow-release or organic fertilizer and follow the manufacturer’s instructions for application rates.

Avoid excessive nitrogen fertilizers, as they can promote lush foliage growth at the expense of flower production. Remember, moderation is key when it comes to fertilizing yarrow.

6. Pruning for Health and Aesthetics:

Pruning yarrow serves multiple purposes. It helps maintain the plant’s shape, improves air circulation, and encourages bushier growth. In late spring or early summer, once the first flush of flowers has faded, trim back the stems to just above a set of healthy leaves or buds.

This will promote branching and result in a more compact and attractive plant. After the second wave of flowering, you can cut the entire plant back by about half to encourage a third round of blooms. Pruning also prevents yarrow from becoming too leggy and ensures a more abundant and vigorous display.

7. Dealing with Pests and Diseases:

Yarrow is known for its ability to repel many common garden pests due to its aromatic foliage. However, some pests like aphids, spider mites, and caterpillars may occasionally pay a visit.

Regularly inspect your plants and manually remove any pests you find. If infestations are severe, consider using organic pest control methods like insecticidal soap or neem oil. Yarrow is generally resistant to diseases, but overwatering and poor air circulation can lead to issues like powdery mildew.

Avoid overhead watering and ensure adequate spacing between plants to prevent such problems. A healthy and well-maintained yarrow plant is less likely to succumb to pests and diseases.

8. Propagation and Division:

Yarrow can be easily propagated through division, which not only helps rejuvenate the plant but also provides an opportunity to expand your yarrow collection or share with fellow gardeners.

Every three to four years, when the clumps become overcrowded, dig up the plant and carefully separate the root system into smaller sections.

Replant these divisions in fresh, well-prepared soil and water thoroughly. This process stimulates new growth and ensures the long-term health and vitality of your yarrow plants.

9. Harvesting and Utilizing Yarrow:

Harvesting yarrow leaves and flowers is a delightful reward for your gardening efforts. For the best flavor and potency, pick the leaves and flowers just as they begin to open.

Yarrow’s flowers come in a range of colors, from white and yellow to pink and red, adding a vibrant touch to your harvest. To preserve the medicinal qualities of yarrow, dry the harvested parts by hanging them upside down in a well-ventilated area.

Once dried, store the leaves and flowers in airtight containers away from sunlight. Yarrow can be used in various ways, such as making herbal teas, infusing oils, creating salves, or adding flavor to culinary dishes. Let your imagination soar and explore the countless possibilities!

Know How to Take Care of Yarrow

Taking care of yarrow is relatively easy, thanks to its hardy nature. Here are a few additional tips to ensure your yarrow plants thrive:


Apply a layer of organic mulch, such as straw or wood chips, around the base of your yarrow plants. Mulching helps retain moisture, suppresses weeds, and maintains a more even soil temperature. Additionally, the mulch will break down over time, enriching the soil with valuable nutrients.

Winter Protection:

Yarrow is generally cold-hardy, but providing a layer of mulch around the plants’ base in late fall can offer extra insulation during severe winters. This layer of mulch helps protect the root system from freezing temperatures and reduces the risk of winter damage.


Regularly remove faded blooms by deadheading yarrow. This not only keeps the plant looking tidy but also encourages continuous blooming throughout the growing season. Deadheading redirects the plant’s energy towards producing new flowers, resulting in a prolonged and abundant display.

Attracting Beneficial Insects:

Yarrow’s abundant nectar-rich flowers attract beneficial insects like bees, butterflies, and ladybugs. By growing yarrow, you’ll be creating a haven for these pollinators, which can benefit your entire garden. The presence of beneficial insects helps control pests and promotes a healthy ecosystem within your garden.

Companion Planting:

Yarrow is a great companion plant as it repels pests and attracts beneficial insects. Consider planting yarrow near vegetables, herbs, or flowering plants to provide natural pest control and enhance overall garden health.

Some excellent companions for yarrow include tomatoes, peppers, chamomile, lavender, and catnip. The intermingling scents and colors will create a visually appealing and harmonious garden space.

Regular Inspections:

Regularly inspect your yarrow plants for any signs of pests, diseases, or nutrient deficiencies. Catching and addressing issues early on can prevent them from spreading and causing more significant damage to your plants.

Look for yellowing leaves, discolored spots, wilting, or any unusual growth patterns. Prompt action will help keep your yarrow plants healthy and vibrant.

Divide Overcrowded Clumps:

As yarrow plants mature, they tend to form overcrowded clumps. Every three to four years, carefully dig up the clumps and divide them into smaller sections. This process not only rejuvenates the plants but also promotes better airflow and prevents diseases.

Replant the divisions in well-prepared soil, ensuring they have enough space to spread and grow.

Provide Adequate Air Circulation:

Good air circulation is crucial for preventing fungal diseases in yarrow plants. Avoid planting them too closely together, as this can create a moist environment that favors the development of diseases like powdery mildew.

Maintain proper spacing between plants to allow for adequate air movement and reduce the risk of fungal infections.

Regular Feeding:

While yarrow doesn’t require heavy feeding, occasional fertilization can promote healthier growth and more abundant blooms. Apply a balanced organic fertilizer in early spring or incorporate compost into the soil to provide a slow-release source of nutrients.

This will ensure that your yarrow plants have the necessary nourishment to thrive throughout the growing season.

In conclusion, growing yarrow is an enjoyable and rewarding experience that adds both beauty and functionality to your garden. By following these nine steps and taking proper care of your yarrow plants, you’ll soon be reaping the benefits of this versatile herb.

So roll up your sleeves, dig in, and let your garden flourish with the vibrant colors and delightful aroma of yarrow! Happy gardening!
