• Overwatering can lead to root rot, so allow the soil to dry out between waterings.

Temperature and Humidity

• Thrives in warm summer conditions but may suffer in extreme heat.
• Prefers dry conditions and may develop root rot in saturated soil.

Fertilizer

• Common yarrow is low-maintenance when it comes to feeding, with minimal fertilization required.
• An annual side-dressing with compost in the spring should be sufficient for healthy growth.

Pruning and Propagating Common Yarrow

Regular pruning is essential to keep common yarrow in a continual state of bloom and prevent self-sowing. Additionally, propagating common yarrow through division allows you to control its growth and share it with others. Here’s how to propagate common yarrow using division:

1. Divide the plant every two to three years to prevent aggressive spread.
2. Transplant the divided sections to other areas of your garden or give them to friends.

Growing Common Yarrow From Seed

Potting and Overwintering Common Yarrow

Growing common yarrow in containers requires attention to pot size and drainage to support its tall growth habit. Additionally, overwintering common yarrow involves cutting back the plant in late autumn to protect it during the winter months.

1. Use a large pot with good drainage for tall varieties of yarrow.
2. Cut back the plant to its basal leaves in late autumn to prepare for winter dormancy.

Common Pests and Diseases

Common yarrow may be susceptible to botrytis mold, powdery mildew, and spittlebugs if its growing conditions are not optimal. Improving soil drainage and providing adequate sunlight can help prevent these issues. Here are some tips for addressing common pests and diseases:

• Botrytis Mold and Powdery Mildew: Improve airflow and drainage to reduce infection.
• Spittlebugs: Use a strong spray of water to reduce the population and exposure to sunlight.

How to Get Common Yarrow to Bloom

Encouraging common yarrow to bloom requires providing ample sunlight and well-drained soil. Deadheading spent blooms regularly can help the plant continue to produce flowers throughout the growing season. Avoid over-fertilizing, as this can lead to rapid growth rather than increased blooming.

Common Problems With Yarrow

Overwatering is a common issue with common yarrow, as it is a drought-tolerant plant that can suffer from root rot in saturated soil. Additionally, the plant may require staking in low-light conditions to prevent leggy growth. Differentiating common yarrow from look-alike plants, such as Queen Anne’s Lace and poison hemlock, is essential for avoiding potential toxicity issues in your garden.
