Catmint Herb Seeds

About Catmint Herb Seeds

Catmint Herb Seeds grow in full sun, partial shade positions. Expect up to 18 inches at maturity. Harvest begins around 60 to 80 days or 90 to 110 days from sowing. 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. Seed can be started indoors ahead of the season or sown straight into prepared ground once it has warmed. Hardy in zones 3 to 8 — your local frost dates decide the exact week.

Where to plant

Choose a site in full sun, partial shade. Water needs are average 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 inches between plants so air can move between them. Plan for up to 18 inches of growth when you place them in a bed or border.

How to plant

Sow 1/2 inch or 1/8 inch deep, spaced 12 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. Indoor starts do best in warmth and bright light; harden the seedlings off over a week before planting out.

How to care

Keep watering average, at the base of the plant rather than over the leaves. In zones 3 to 8 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth. Expect to start harvesting around 60 to 80 days or 90 to 110 days after sowing.
