Marshmallow Herb Seeds

About Marshmallow Herb Seeds

Marshmallow Herb 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, summer. Sow directly where the plants are to grow; this variety does not transplant happily. The seed needs a cold, moist period before it will break dormancy: sow in late fall and let winter do the work, or chill it in damp medium in the refrigerator first. Hardy in zones 3 to 9 — your local frost dates decide the exact week.

Where to plant

Choose a site in full sun, partial shade. 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 18 inches between plants so air can move between them.

How to plant

Sow 1/4 inch deep, spaced 18 inches apart. 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.
