Growing Yarrow
- Location: Choose a sunny spot with well-drained soil. Yarrow can tolerate poor soil conditions and drought, but it thrives in sunny, open areas.
- Planting: Sow yarrow seeds directly in the garden in early spring or start indoors 6-8 weeks before the last frost. Alternatively, you can propagate yarrow by dividing established plants in early spring or fall.
- Spacing: Space yarrow plants about 12 inches apart to allow for proper air circulation and growth.
- Watering: Water yarrow moderately, allowing the soil to dry out between waterings. Overwatering can lead to root rot and other issues.
- Maintenance: Deadhead spent flowers to encourage continuous blooming. Yarrow is a low-maintenance plant, but occasional pruning helps maintain its shape and vigor.
Harvesting Yarrow
- Timing: Harvest yarrow flowers and leaves during peak bloom, typically in late spring to early summer, when the essential oils are most concentrated.
- Method: Use sharp scissors or pruning shears to cut the stems just above the leaves. Harvest in the morning after the dew has dried but before the heat of the day.
- Drying: Bundle yarrow stems and hang them upside down in a cool, dry, and well-ventilated area. Alternatively, use a dehydrator set to low heat to dry yarrow quickly.
- Storage: Store dried yarrow in airtight containers away from direct sunlight to preserve its potency.
Safety Considerations
Yarrow is generally safe for most people when used in moderation. However, there are some considerations to keep in mind:
- Pregnancy: Avoid using yarrow during pregnancy, as it may stimulate uterine contractions.
- Allergies: Individuals allergic to plants in the Asteraceae family, such as ragweed and chamomile, may also be sensitive to yarrow.
- Interactions: Yarrow may interact with blood-thinning medications, so consult a healthcare professional before use if you are taking such medications.
