Description

Tasty and incredibly nutritious Leek ‘Mercurian’ is a reliable cropper with great flavour, excellent nutritional benefits and uniform straight white and tender stems which don’t bulb at the base. The leaves are upright and tend not to droop which means they take up less space on the allotment. Sow these leeks successively from May to July and enjoy a harvest season which lasts throughout autumn and into winter. Perfect for soups, stews and casseroles or simply as a side to your favourite hearty dinners! Sow indoors 4-5 seeds in 5cm pots or used vending cups, or very thinly in a seed tray of good quality seed compost. Cover with 6mm of vermiculite or compost, and maintain at a temperature of 15- 20C until germination, which usually takes 14 -21 days. Once germinated, grow leek plants on in cool conditions. Alternatively, sow thinly directly outside, 1cm deep in drills 30cm apart in soil which has been raked to a fine tilth. Carefully lift when plants are large enough to handle and transplant from mid-June to mid-July at a spacing of 23-25cm apart and 45cm between rows, using a trowel or dibber, and water in. Water the plants thoroughly after planting. Keep watered during dry weather. Earth up the stems during the growing season to increase the length of the blanched stem. High in folic acid, potassium, pro-vitamin A and vitamin C. Position: Full Sun . Height: Up to 45cm when fully established .
