Harris Model Parsnip
Parsnip seed does not keep well from year to year; use only fresh seed, sowing as early as ground can be worked. Sow seed 1⁄2 inches deep in rows 18-24 inches apart. Thin to 3 inches apart. Adequate moisture and a cool soil temperature of 15-18 degrees C is essential for good germination which may take up to 21 days.
Full sun and soil pH of 6.5. Requires a rich, deeply cultivated soil with plenty of organic matter; incorporate compost or well-rotted manure prior to planting.
Harvest any time once roots are adequately sized. Parsnips are tender and flavourful in the fall. A few light frosts will improve the flavour. They may also be mulched and left in ground over winter and dug as the ground thaws.
Parsnips are fairly pest-free and disease-free, however, they are susceptible to root maggot damage. Use row covers to protect young seedlings early in the season.
