Red Yarrow Seeds

Red Yarrow seeds can be sown outdoors in fall or spring, or started indoors 6–8 weeks before the last frost. Because Achillea Millefolium seeds require light to germinate, press them gently onto the soil surface rather than burying them. Maintain a temperature of 65–75°F and keep the medium consistently moist; yarrow seeds sprout in 20–45 days. Space seedlings 4–6 inches apart — they'll spread over time, and crowding early just creates competition for air.

Red Yarrow herb seeds thrive in full sun — at least 6 hours of direct light daily, and performs best in well-drained, even sandy or lean soil. Rich, fertile soil can actually cause floppy stems, so avoid over-amending; in shaded or overly fertile beds, staking may be needed. Water young yarrow transplants regularly until roots are established, then scale back, as yarrow's deep root system handles brief dry spells with ease.

Once established, Red Yarrow is remarkably self-sufficient and requires very little intervention. Deadhead spent flower clusters regularly to encourage a second flush of blooms and keep the plant looking tidy through late summer. Every 3–4 years, divide the clumps in spring or fall to refresh vigor, prevent overcrowding, and multiply your planting for free. For herbal use, harvest stems just as the first florets open and hang them upside down in a dry, airy room; the heads hold their red color beautifully for dried bouquets, yarrow tea, skin salves, or tinctures.
