Parsnip 'Harris Model'

Parsnips are best eaten after the first hard frost. The frost actually converts the starch in the root into sugar, making them sweet. It’s best to harvest in mid winter, or in early spring after the soil thaws. If planning to harvest in the spring, mulch heavily so the roots won’t rot in the grown. Some varieties are better ground keepers than others. Harris Model is an exceptional ground keeper, reportedly not even necessarily needing mulching.

Double digging is a good practise when planting parsnips. As with carrots, if the soil is too hard or rocky, the growth will be stunted and splits will form in the root.

Plant in a location that enjoys partial sun and remember to water moderately. Keep in mind when planting that Harris Model is thought of as half hardy, so it will need protecting in periods of cold weather. Planting Harris Model in loamy soil with a ph of between 6.0 and 6.5 is ideal for as it does best in weakly acidic soil.

Slow to germinate.

Aim to sow 0.47 inches (1.2 cm) deep and try to ensure a gap of at least 0.98 inches (2.5 cm). Soil temperature should be kept higher than 16°C / 61°F to ensure good germination.

By our calculations, you should look at sowing Harris Model about 15 days after your last frost date.

As Harris Model is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.

Harvest after a few good frosts.

This variety tends to be ready for harvesting by early winter.
