Yarrow (*Achillea millefolium*) is a versatile and hardy perennial plant known for its medicinal properties and attractive blooms. Harvesting yarrow at the right time and storing it properly ensures maximum potency and longevity. This guide provides essential tips for collecting and preserving yarrow blooms effectively.
When to Harvest Yarrow
The best time to harvest yarrow is during its peak bloom, which typically occurs in late spring to early summer. Look for blooms that are fully open but not yet fading. Harvesting at this stage ensures the highest concentration of essential oils and active compounds.
How to Collect Yarrow Blooms
Use sharp, clean scissors or pruning shears to cut the flower stalks. Cut the stems about 4-6 inches below the flower head, leaving some foliage intact. This promotes healthy regrowth and prevents damage to the plant.
Choose a dry, sunny day for harvesting to prevent excess moisture, which can lead to mold during storage. Handle the blooms gently to avoid bruising or crushing.
Drying and Storing Yarrow Blooms
Proper drying is crucial to preserve yarrow’s medicinal qualities. Bundle several stems together with natural twine, ensuring good air circulation. Hang the bundles upside down in a warm, dry, and well-ventilated space away from direct sunlight.
Allow the yarrow to dry for about two weeks or until the flowers feel crisp and brittle. Once dried, remove the blooms from the stems and store them in airtight containers, such as glass jars or metal tins. Keep the containers in a cool, dark place to maintain potency.
Additional Tips for Harvesting Yarrow
- Harvest in the morning after dew has dried for the best quality.
- Avoid harvesting during or immediately after rain to prevent moisture-related spoilage.
- Regularly check stored yarrow for signs of mold or pests and remove affected portions.
- Label stored batches with the harvest date for future reference.
With proper timing and storage techniques, harvesting yarrow can yield a vibrant and potent supply of this valuable herb for teas, tinctures, and other herbal remedies. Consistent care ensures you enjoy the benefits of yarrow throughout the year.
