Growing Parsnips from Seeds.  Sowing
Sow in late March to around the 3rd week in May as germination is the trickiest part of growing parsnips, and seed sown too early is more likely to fail. If you are determined to sow earlier, warm the soil with cloches prior to sowing and leave the cloches in place until the seedlings have established. Sow 2 seeds together, half an inch deep, 15cm apart in rows 30cm apart. Growing On Thin once the seedlings are approximately 3cm high, thin out leaving one plant per 15cm. If you are short of space or want to grow smaller parsnips, sow closer together, 20cm apart and thin to about 8cm. Alternatively, selected parsnip varieties can be grown in containers which will produce mini roots. An evenly moist soil will help prevent splitting so water if the weather is dry and apply a mulch to aid water retention. Harvesting Harvesting begins in September, once the foliage begins to die down and continues into the following spring. Roots can be left in the ground in the winter and lifted as necessary. Frosts improve the flavour but you may be wise to lift extra in November before the ground freezes. Lift the roots using a fork, being careful not to damage them. Parsnips can be stored in boxes of moist soil for up to a month, in a cool, dark place. |
