Yarrow
Yarrow (Achillea millefolium)
is a versatile and hardy perennial herb known for its feathery foliage and clusters of tiny flowers. Belonging to the Asteraceae family, this herbaceous plant is native to temperate regions of the Northern Hemisphere. Yarrow has a rich history of medicinal use, culinary applications, and ornamental value. In this blog, we’ll explore how to grow yarrow from seed and provide tips on cultivating this beneficial plant.
Planting Yarrow from Seed
1. Seed Selection: Begin by selecting high-quality yarrow seeds from a reputable supplier or collect seeds from existing plants. Yarrow seeds are small and light brown in colour.
2. Timing: Yarrow seeds can be sown either in spring or autumn. Choose a time when the soil temperature is around 60-70°F (15-21°C) for optimal germination.
3. Site Selection: Yarrow thrives in full sun but can tolerate partial shade. Select a well-draining location with nutrient-rich soil.
4. Soil Preparation: Prepare the soil by loosening it with a garden fork or tiller. Remove any weeds, rocks, or debris that may hinder seed germination.
5. Sowing Seeds: Scatter yarrow seeds evenly over the prepared soil surface. Press the seeds lightly into the soil but avoid covering them with a thick layer of soil, as yarrow seeds require light to germinate.
6. Watering: Water the seeded area gently using a fine mist or a watering can with a rose attachment. Keep the soil consistently moist but not waterlogged.
7. Germination: Yarrow seeds typically germinate within 14-21 days under favourable conditions. During this period, ensure adequate moisture and sunlight for optimal growth.
8. Thinning: Once the seedlings have emerged and developed a few true leaves, thin them to maintain spacing of about 12-18 inches (30-45 cm) between plants.
Growing Yarrow
Sunlight: Yarrow prefers full sun but can tolerate partial shade.
Soil: Well-draining soil with a pH range of 6.0-7.0 is ideal for yarrow. Avoid waterlogged or compacted soils.
Watering: While yarrow is drought-tolerant once established, regular watering is necessary during periods of prolonged drought, especially for newly planted specimens.
Fertilisation: Yarrow is not heavy feeder; however, incorporating compost or a balanced fertiliser into the soil during planting can promote healthy growth.
Maintenance: Yarrow is relatively low-maintenance. Deadhead spent flowers to encourage continuous blooming and prevent self-seeding. Dividing clumps every 2-3 years helps rejuvenate older plants.
Medicinal Qualities of Yarrow
Yarrow has been valued for centuries for its medicinal properties. Here are some of its key medicinal qualities:
1. Anti-inflammatory: Yarrow contains compounds such as flavonoids and sesquiterpene lactones that exhibit anti-inflammatory effects. It can be used topically to reduce inflammation associated with bruises, sprains, and minor wounds.
2. Antimicrobial: Yarrow possesses antimicrobial properties due to its high content of volatile oils, including azulene. It can be applied as a poultice or used in herbal teas to help combat infections and promote wound healing.
3. Hemostatic: Yarrow has hemostatic properties, meaning it can help stop bleeding. It contains astringent compounds that constrict blood vessels and promote clotting. Yarrow poultices or compresses can be applied to minor cuts, nosebleeds, and other superficial wounds.
4. Digestive Aid: Yarrow is traditionally used to support digestive health. It stimulates appetite, aids digestion, and can help alleviate symptoms of indigestion, bloating, and cramping.
5. Immune Support: Yarrow is believed to have immune-boosting properties. Consuming yarrow tea or tinctures may help strengthen the immune system and promote overall wellness.
6. Menstrual Support: Yarrow has been used historically to relieve menstrual cramps and regulate menstrual flow. It is believed to have mild emmenagogue properties, meaning it can promote menstruation.
7. Fever Reducer: Yarrow is considered a febrifuge, meaning it can help reduce fever. It induces sweating, which can help the body expel toxins and lower body temperature during febrile illnesses.
