About Yarrow Flower Seeds
Yarrow Flower Seeds grow in full sun positions. Flowering runs summer. The figures below are the ones on the packets in this group; each product page carries the exact numbers for that variety.
When to plant
Plant in fall, spring. Sow directly where the plants are to grow; this variety does not transplant happily. Hardy in zones 3 to 9 — your local frost dates decide the exact week.
Where to plant
Choose a site in full sun. Water needs are low once the plants are established. Free-draining soil matters more than rich soil; seed sown into ground that stays wet rots before it germinates. Allow 12 to 24 inches between plants so air can move between them.
How to plant
Sow 1/8 inch deep, spaced 12 to 24 inches apart. This seed needs light to germinate, so press it onto the surface and firm it in rather than burying it. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear.
How to care
Keep watering low, at the base of the plant rather than over the leaves. In zones 3 to 9 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth. Flowers appear summer; cutting or deadheading regularly keeps more coming.
