Yarrow (Achillea millefolium) is a popular perennial plant valued for its vibrant flowers and medicinal properties. Proper care throughout the year ensures healthy growth and abundant blooms. This month-by-month guide provides essential tips to help you maintain your yarrow plants in all seasons.
Spring Yarrow Care
Spring is the time to prepare your yarrow for the growing season. As the weather warms, follow these steps:
- Remove any dead or damaged stems from winter dormancy.
- Thin out overcrowded plants to improve air circulation.
- Apply a light layer of compost around the base to nourish the soil.
- Start watering regularly as the soil warms up.
- If planting new yarrow, do so after the last frost date.
Summer Yarrow Care
During summer, yarrow thrives with proper watering and maintenance. Keep these tips in mind:
- Water deeply once a week, especially during dry spells.
- Deadhead spent flowers to encourage continuous blooming.
- Ensure the plant receives at least 6 hours of sunlight daily.
- Mulch around the base to retain moisture and suppress weeds.
- Watch for pests such as aphids and treat promptly if needed.
Autumn Yarrow Care
As temperatures drop, prepare yarrow for winter. Follow these steps:
- Reduce watering gradually as the plant enters dormancy.
- Cut back the stems to about 2 inches above the soil to promote healthy growth next season.
- Apply a layer of mulch to protect roots from freezing temperatures.
- Remove fallen leaves and debris around the plant.
Winter Yarrow Care
In winter, yarrow generally remains dormant. Minimal care is needed, but keep these tips in mind:
- Ensure mulch remains in place to insulate roots.
- Avoid overwatering; water only if the soil is extremely dry.
- Protect plants from harsh winds with windbreaks if necessary.
- Check periodically for signs of disease or pest activity.
Additional Tips for Yarrow Care
Beyond seasonal care, consider these general tips to keep your yarrow healthy:
- Plant yarrow in well-drained soil to prevent root rot.
- Divide mature plants every 3-4 years to maintain vigor.
- Use organic fertilizers sparingly; yarrow prefers lean soil.
- Monitor for diseases such as powdery mildew and treat early.
