About Forget Me Not Flower Seeds
Forget Me Not Flower Seeds grow in full sun, partial shade positions. 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, summer. Seed can be started indoors ahead of the season or sown straight into prepared ground once it has warmed. Hardy in zones 3 to 10 — your local frost dates decide the exact week.
Where to plant
Choose a site in full sun, partial shade. Water needs are high 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 15 to 18 inches or 6 to 12 inches between plants so air can move between them.
How to plant
Sow 1/8 inch deep, spaced 15 to 18 inches or 6 to 12 inches apart. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear. Indoor starts do best in warmth and bright light; harden the seedlings off over a week before planting out.
How to care
Keep watering high, at the base of the plant rather than over the leaves. In zones 3 to 10 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth.
