Name: Parsnip: Tender & True Latin Name: Pastinaca sativa Description: Tender and True Parsnip is easy to grow. It can withstand quite a bit of frost. The parsnips look a little like winter carrots both in terms of size and appearance, although they are a little less sweet compared to winter carrots. Seed Origin: Netherlands Sowing: March to May Harvesting: October to March How To Grow Parsnip From Seed: Sow parsnip seed directly outside in drills that are 35cm apart. Having the ground you are planting them in well worked and loose will help your parsnips grow straight downwards. Parsnip seed germination can be erratic, to allow for this, sow a few seeds evenly every 15cm. When they germinate, thin them to leave the strongest seedling every 15cm. Harvesting can start in Autumn, but waiting until the first frost is thought to improve their flavour. Parsnips can stay in the ground over winter. Seed count is approximate.
