Growing Tips for Parsnip in Zone
Zone has a short growing season (~123 days). Start Parsnip indoors early and use season-extension techniques like row covers and cold frames.
Use only fresh seed as parsnip seed viability declines rapidly. Sow directly in spring in deeply worked soil. Leave roots in the ground through winter for sweetest flavor.
