Onion - Santero F1 Hybrid
This is the answer to gardeners' prayers. This is the first bulb onion resistant to the devastating downy mildew, a fungal disease of the leaves, which affects yield, bulb quality and keeping qualities. It is a maincrop with quality copper brown skinned bulbs with crisp white flesh. Store sound and unblemished bulbs in trays or old tights in a dry, airy but frost free site for use throughout the winter.
Sow mid-March to April. Sow seed thinly 1cm deep, in drills 30cm apart. When large enough to handle, thin seedlings to 7-10cm apart for medium sized bulbs, or slightly wider spacing if larger bulbs are required. Keep well-watered during dry weather especially during early stages of growth as the bulb swells. Do not bend leaves over, just wait for them to yellow and wither naturally, then lift bulbs on a sunny day and leave on soil surface to dry.
