About Asparagus Vegetable Seeds
Asparagus Vegetable Seeds grow in full sun, partial shade positions. Expect 24 to 30 inches or 36 to 48 inches at maturity. 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 cool season, warm season. 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 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. Plan for 24 to 30 inches or 36 to 48 inches of growth when you place them in a bed or border.
How to plant
Follow the depth given on the product page; it differs between the varieties in this group. 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 10 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth.
