We Recommend: Gladiator (PN581). This hybrid parsnip was bred to be fast-growing, uniform, and large – and we’ve seen some HUGE ones! At any size it has very appealing, mild flavour and it’s firm without being woody.

Timing
Direct sow from late March to early July. Optimal soil temperature for germination: 10-25°C (50-75°F). Seeds take 14-21 days to germinate.

Starting
Sow seeds 5mm-1cm (¼-½”) deep. Cover seeds with compost and/or put row cover over planting area to shade the soil and conserve moisture. Thin to 7-10 cm (3-4″) apart in rows 45-60cm (18-24″) apart.

Growing
Ideal pH: 6.0-6.8. Prepare ground as for carrots, digging deeply to loosen soil prior to planting For even longer parsnips, you can dig or form holes 60cm (24″) deep. Weed carefully and keep watered.

Harvest
Flavour is best after a couple of good frosts. Dig parsnips from October 1st through the winter as needed. Protect from freezing in the soil with a thick straw mulch if it is a cold winter. Parsnips keep better in well-drained soil. The average family will be well supplied with a 6m (20′) row.
