CULTURAL PRACTICES: Must be sown very early, as soon as the ground can be properly worked. Spanish onions must be sown indoors, between the beginning and the end of February.
SOIL: A rich and fertile soil of mineral or organic matter. Soil must be kept moist but not wet.
SPACING: Space rows 35 to 38 cm apart. For larger bulbs, clear the plants 7 to 8 cm apart Thinned plants taste great in a salad.
GROWING TIPS: Applying a fertilizer is recommended and should be repeated when the bulbs begin to swell.
HARVESTING: Storage onions: when the onion tops begin to fall over, turn brown and wither. Drying may be accelerated by bending down some of the tops. Pick the onions then place them in a warm, dry, ventilated area to preserve. When dried, store the onions in a cool, dry location. Bunching Onions: it is best to harvest them when they are young and green.
