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.

Flowering Months Harvest Months
Onions are undemanding and require only occasional watering during particularly dry periods. However, rows should be weeded regularly. Harvest onions in late June and July, a week or two after the leaves begin to turn yellow. Choose a dry day to loosen them from the ground with a fork. Leave them on the soil surface for a day or two until they have fully dried in the sun. Once dry, remove the top foliage and store them in a well ventilated, dry position. Bulbs can be stored for several months.

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.
