- Test Soil pH: Use a home testing kit to check the soil’s pH level, adjusting it as necessary with lime (to increase pH) or sulfur (to decrease pH).
- Amend the Soil: Incorporate organic matter such as compost to enrich the soil and improve drainage.
How to Plant Yarrow
Once your site has been prepared, you are ready to plant yarrow.
Planting Seeds vs. Transplants
You have the option to plant yarrow from seeds or transplants:
Planting Seeds
- When to Sow: For best results, sow seeds indoors 6 to 8 weeks before the last frost, or directly in your garden after the danger of frost has passed.
- Sowing Method: Scatter seeds on the soil surface, lightly pressing them into the soil without covering them, as they need light to germinate.
Transplanting Seedlings
- Timing: If using seedlings, transplant them in spring after the last frost when soil temperatures have warmed.
- Spacing: Space your seedlings 12-18 inches apart to ensure good airflow and prevent overcrowding.
Caring for Your Yarrow Plants
Once planted, yarrow requires minimal care, making it an ideal choice for low-maintenance gardens.
Watering Needs
Yarrow is drought-resistant; however, young plants require regular watering to establish their roots. Once established, water sparingly, allowing the soil to dry out between waterings. Overwatering can lead to root rot, so it’s better to err on the side of underwatering.
Fertilization
Yarrow typically doesn’t require heavy fertilization. If your soil is poor, a light application of a balanced fertilizer in early spring can boost growth.
Pruning and Deadheading
For a healthier plant and extended blooming period, practice deadheading—removing spent flowers—to encourage more blooms throughout the season. After flowering, cut back the stems to promote a bushier growth for the following year.
Pest and Disease Management
Yarrow is generally resistant to pests and diseases but can occasionally be affected by aphids, spider mites, or powdery mildew under humid conditions.
Natural Remedies for Pests
- Aphids: Introduce ladybugs or apply insecticidal soap.
- Spider Mites: Increase humidity or water with a strong spray to remove them.
Harvesting Yarrow
If you plan on utilizing yarrow for its medicinal benefits, knowing when and how to harvest is vital.
When to Harvest
The best time to harvest yarrow is when the flowers are in full bloom. This usually occurs in midsummer.
Harvesting Method
Use sharp scissors or pruning shears to cut stems, leaving a few inches above the ground to encourage regrowth. Gather stems in small bundles and hang them upside down in a dark, dry area to dry.
Using Yarrow in the Garden
Yarrow’s versatility makes it suitable for a variety of garden applications.
Companion Planting
Yarrow pairs well with a wide range of plants. Its foliage can deter pests such as aphids and other insects. It is especially beneficial when planted alongside:
- Vegetables: Tomatoes, carrots, and members of the brassica family.
- Flowers: Echinacea, lavender, and other pollinator-friendly plants.
Creating a Yarrow Garden Bed
Consider dedicating a specific garden bed to yarrow and other flowering herbs. This bed can serve not only as an attractive landscape feature but also as a habitat for pollinators.

What is Yarrow, and why should I plant it in my garden?
Yarrow, scientifically known as Achillea millefolium, is a versatile perennial plant celebrated for its feathery foliage and clusters of small flowers. This hardy plant is often used in herbal medicine and traditional remedies, thanks to its anti-inflammatory and antimicrobial properties. Additionally, yarrow attracts beneficial insects like butterflies and ladybugs to your garden, making it an excellent choice for gardeners interested in promoting biodiversity.
Planting yarrow can also enhance your garden’s aesthetics, as it comes in various colors, including white, yellow, pink, and red. It thrives in poor soil conditions, making it a perfect option for challenging areas where other plants may struggle. Moreover, yarrow is drought-tolerant once established, reducing the need for extensive watering and maintenance, which is ideal for xeriscaping.
When is the best time to plant yarrow?
The ideal time to plant yarrow is in either the spring or fall when temperatures are milder. If you’re planting seeds, early spring after the last frost is a great time to sow them directly into the garden. Alternatively, you can start seeds indoors about 6-8 weeks before the last frost date and transplant the seedlings outside once they’ve hardened off. Planting in the fall allows the roots to establish before winter, leading to vigorous growth in the spring.
If you prefer to plant division or nursery-bought plants, you can do so in either spring or early fall. This timing will help ensure that the plants get enough time to adjust to their new environment and establish roots before extreme temperatures set in. Pay attention to local climate conditions, as specific planting times can vary based on your USDA hardiness zone.
How do I prepare the soil before planting yarrow?
Preparing the soil for yarrow is crucial for healthy growth. Start by choosing a sunny location, as yarrow thrives in full sunlight. The soil should be well-draining, as yarrow does not tolerate waterlogged conditions. Ideally, you should amend the soil with organic matter, such as compost, to improve fertility and drainage, especially if the soil quality is poor. Aim for a soil pH between 6.0 and 7.5 for optimal growth.
To prepare the planting area, remove weeds and debris, and till the soil to a depth of about 12 inches. Mix in compost or other organic amendments thoroughly to enhance nutrient availability. If you’re planting in heavy clay soils, consider creating raised beds or incorporating sand to improve drainage and aeration. After preparing the soil, you can sow seeds or transplant seedlings as needed.
What care does yarrow require after planting?
Once established, yarrow is low-maintenance, which is one of its notable advantages. However, during the initial growing period, it’s important to keep the soil consistently moist, especially if your area is experiencing a dry spell. Water regularly to ensure seedlings develop a strong root system, but avoid overwatering as yarrow can be sensitive to excessive moisture. Once established, yarrow can tolerate periods of drought.
Additionally, deadheading spent flowers will encourage more blooms throughout the growing season and maintain the plant’s aesthetic appeal. While yarrow is resistant to most pests and diseases, it’s wise to keep an eye out for any signs of trouble and address them quickly. Fertilization needs are minimal; if desired, you can apply a balanced fertilizer in early spring to support growth, but this is generally not necessary for healthy yarrow plants.
Can yarrow be propagated, and if so, how?
Yes, yarrow can be easily propagated through seeds, division, or cuttings. Seed propagation is straightforward; simply scatter the seeds in prepared soil and lightly cover them. Keep the soil moist until germination occurs, which typically takes about 14-30 days. If you’re harvesting seeds from an existing plant, do so in late summer when the flower heads have dried out, and then store them in a cool, dry place until you’re ready to plant.
Alternatively, you can propagate yarrow through division. This method is best done in spring or early fall. Dig up an established yarrow plant and carefully separate the root clumps into smaller sections using a sharp spade or garden knife. Replant the divisions immediately at the same depth they were originally growing. Ensuring that each division has healthy root structures will help them establish quickly in their new locations.
Is yarrow safe for pets and children?
Yarrow is generally considered safe for gardens where children and pets play. However, it’s worth noting that yarrow does contain compounds that can cause mild irritation in some individuals, particularly when ingested in larger quantities. For this reason, it’s a good idea to teach children not to eat any unknown plants and to monitor pets if they show an interest in chewing on the foliage.
Most importantly, yarrow is not known to be highly toxic to pets or children, unlike some other garden plants. If ingested in small amounts, it usually does not lead to severe reactions. However, as with any plant, individual sensitivities can vary, so it’s always best to consult with your veterinarian or a medical professional if any adverse reactions occur after ingestion.
