Thompson & Morgan Onion Hi Keeper F1 Hybrid 1 Seed Packet

This fantastic variety of onion will produce quality yellow skinned globe shaped bulbs that will weight up 120g (4oz) each. With excellent winter hardiness these are the best variety for overwintering when sown indoors in Autumn. Equally as good planted in spring, and when planted alongside mint this will confuse and deter onion flyDirect sow onions outdoors in spring on any firm, well drained soil in full sun. Sow thinly at a depth of 1cm (1/2") and a distance of 30cm (12") between rows. Prepare the planting area several weeks in advance by incorporating some well rotted garden compost to improve drainage and soil fertility. Avoid planting onions on freshly manured soil. On particularly wet ground, try growing onions in raised beds. When large enough to handle, thin onion seedlings to 10cm (4") apart for medium sized bulbs, or at a slightly wider spacing if larger bulbs are required.Product Specifications: Hardy Annual.
