Spring planting. Heat treated.
The answer to gardeners' prayers! Heat treated early main crop, Onion 'Santero' F1 Hybrid is the first onion set with resistance to downy mildew, a potentially disastrous fungal foliage disease. This 'Rijnsburger' type onion produces copper brown, oval-to-round bulbs with medium skin thickness. Yields are similar in quality and quantity to other F1 maincrop varieties currently available, and bulbs have great storage potential. Height: 45cm (18"). Spread: 15cm (6").
Companion planting: Try growing onions with mint to confuse and deter onion fly.
Up to 45cm (17.7in)

Plant onions in rows in any firm, well drained soil in full sun. 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 growing onions from sets, plant the bulbs so that the tip of bulb is just protruding through the soil surface. Onion plants should be grown on to at least 15cm (6") tall before being gradually acclimatised to outdoor conditions prior to planting outdoors. Leave a space of 10cm (4") between each onion, and 30cm (12") between each row. Cover with a protective netting or fleece to prevent attack from birds and insects. Water the onion plants thoroughly after planting.
