Yarrow plants are popular in gardens for their vibrant flowers and hardy nature. However, many gardeners make the mistake of overwatering these resilient plants, which can lead to serious problems.
Understanding Yarrow’s Water Needs
Yarrow (Achillea millefolium) is a drought-tolerant perennial that thrives in well-drained soil. Its natural habitat includes dry meadows and open slopes, where excessive moisture is rare. Overwatering can disrupt its health and growth.
The Risks of Overwatering Yarrow
- Root Rot: Excess water can cause roots to rot, leading to plant decline or death.
- Fungal Diseases: Overly moist conditions promote fungal infections like powdery mildew.
- Weak Growth: Too much water hampers the plant’s ability to develop strong, healthy stems and leaves.
- Reduced Flowering: Excess moisture can inhibit blooming and reduce flower production.
Signs Your Yarrow Is Overwatered
Recognizing overwatering early can save your plant. Look for these signs:
- Yellowing leaves that feel soft and limp
- Wilting despite moist soil
- Foul smell from the soil
- Presence of mold or fungi on the soil surface
Proper Watering Practices for Yarrow
To keep your yarrow healthy, follow these watering tips:
- Water deeply but infrequently, allowing the soil to dry out between watering sessions.
- Check soil moisture before watering by feeling the top inch of soil.
- Ensure the planting area has well-draining soil to prevent water accumulation.

Additional Tips for Healthy Yarrow Growth
Besides proper watering, consider these tips:
- Plant yarrow in full sun for optimal growth and flowering.
