Yarrow, also known as Achillea, is a versatile and low-maintenance plant that is commonly used in gardens and landscapes. Whether you choose to start with plant starts or grow it from seed, yarrow is relatively easy to care for once it is established.
Planting yarrow is best done in well-drained soil. It can tolerate a wide range of soil types, but it thrives in soil that is not overly wet or compacted. Before planting, make sure to prepare the soil by loosening it with a garden fork or tiller. This will help improve drainage and provide a better environment for the roots to grow.
When it comes to watering, yarrow prefers regular moisture, especially during dry periods. However, it is important to allow the soil to fully dry out between waterings to prevent overwatering, as this can lead to root rot. It is a good practice to check the soil moisture level by sticking your finger into the soil up to your knuckle. If it feels dry at that depth, it’s time to water. During periods of heavy rainfall, you may not need to water at all.
Yarrow has a deep root system, which helps it access moisture and nutrients from deeper in the soil. This makes it relatively drought-tolerant once established. However, during prolonged drought conditions, it is beneficial to give yarrow a deep watering to ensure its health and vitality.
Fertilizing yarrow is generally not necessary, as it can thrive in soil with average fertility. However, if you want to give it a boost, you can apply a balanced, slow-release fertilizer in the spring. Avoid using excessive amounts of nitrogen, as this can lead to excessive growth and weaker stems.
In terms of pruning, yarrow benefits from regular deadheading. This involves removing spent flowers to encourage continuous blooming and prevent the plant from going to seed. Deadheading also helps maintain a neat appearance and prevents self-seeding, which can lead to invasive growth.
Yarrow is relatively pest and disease-resistant, making it a low-maintenance plant. However, it may occasionally attract aphids or powdery mildew. If you notice these issues, you can wash off aphids with a strong stream of water or use insecticidal soap. Powdery mildew can be prevented by providing good air circulation and avoiding overhead watering.
Yarrow is a hardy and resilient plant that requires minimal maintenance once established. With proper soil preparation, regular watering, occasional deadheading, and minimal fertilization, you can enjoy the beauty of yarrow in your garden for years to come.
