Pastinaca sativa This hearty, sweet vegetable is often overlooked by gardeners, yet it deserves a place in both spring and fall plantings. A rich source of copper, this trace element is said to support hemoglobin formation for healthy bones, blood vessels, and nerves.

Days to maturity are calculated from date of direct seeding.

• Parsnips perform best in deeply worked, well-composted, loose soil with a pH of 6.0-7.0
• High nitrogen fertilizer or manure can cause roots to fork and become hairy
• Avoid compacting the soil as parsnips are deeply rooted
• Keep well watered through the growing season

Direct Sowing
• Dig a shallow furrow and lightly cover seed with soil, vermiculite or sifted compost
• Water evenly and regularly to prevent soil crusting
• Row cover beds when soil temperatures are cool and to help prevent soil crusting
• Thin when plants are 4 inches tall
• Savvy gardeners plant radish seed in the furrow with parsnips to help break the soil surface for slower-growing parsnips
• Sow mid-June—July for a fall/winter crop

Insects & Diseases
Common insects: Carrot rust fly maggots
Insect control: Reemay or Summer Insect Barrier, until tops are 3-4 inches tall
