Turnips (Brassica rapa) are quick growing, root vegetables, ideal for stews and stir fries. Modern varieties are tender and fast cropping, ready in around six to eight weeks from sowing to harvesting.
Soil Type: Sandy, deeply dug, loam with plenty of organic matter added.
Conditions: Full sun.
Ease of Cultivation: Easy.
Type: Root Vegetable.
Hardiness: Hardy in most regions of the UK.
When to Sow: March to May.
Harvest Season: Late summer to autumn.
They grow best in a light, well cultivated soil, that has been manured in the previous season. Although a heavier soil will do, so long as it is well drained. Dig the soil over and break down to a fine tilth. Rake-in a general purpose fertiliser a few weeks before sowing. Lime the soil if necessary.
Sowings may be made in the open from March to August. Successional sow every few weeks to ensure a regular harvest.
Can be sown as early as late February under cloches.
Maincrop varieties are usually sown from July to August
for harvesting in
November and December.
Sow seed in shallow drills approximately 12in (30cm) between rows or equidistant in raised beds. Young plants should be thinned to at least 6in (15cm) apart.
Keep weed free and water as required.
As part of the brassica family club-root can be an issue. Modern, fast growing varieties are less affected. They are also vulnerable to cabbage root fly.
Harvest as soon as the roots are large enough to use, approximately 6 to 10 weeks after sowing.
Turnips are best harvested when small and tender. As they grow-on they become less tender and less flavoursome.
Cover with a few inches of leaves or straw and leave in the ground over winter. In the spring, any roots left will send up a crop of young green shoots called "turnip-tops", which are edible as leafy greens.
Like swedes, turnips are traditionally cooked in pies, casseroles and stews. Modern hybrid varieties tend to be smaller and much more tender, and can be delicious grated raw into a salad.
Wash thoroughly. Trim off the stalk and root, and peel. Small turnips can be cooked whole or larger ones cut into chunks or slices. Boil in lightly salted water until tender.
Low in calories, they are high in vitamins, potassium and dietary fiber.
