They are the ideal veg to grow for winter use, are relatively trouble-free and not too fussy about soil conditions.

Sow now thinly in a short row in the open ground, covering the seed to a depth of 1cm and water thoroughly. If you sowed them under glass earlier in the year they can be planted out from May to July. They’ll grow in any type of soil and their strong roots help break up heavy ground. When seedlings are around 15cm tall, lift and transplant them, trimming the ends of the leaves and any damaged roots with scissors beforehand.

Then make holes with a dibber around 15cm deep and 15cm apart and drop a seedling into each, leaving the top 5cm of foliage above ground and pushing a little soil down into each hole to cover the roots. You can harvest them from early winter, lifting the root with a fork. Good varieties include Musselburgh and Oarsman.
