White onionHow do I sow white onions outdoors?
To sow white onions outdoors, we recommend doing so in spring, once the risk of frost has passed. Choose a sunny spot with well-drained soil. Before sowing, work the soil by hoeing and weeding. Do not add chemical fertilisers, favour compost to enrich the soil naturally.
White onion seeds should be sown about 1 cm deep and spaced about 10 cm apart. Be sure to keep the soil moist but not soggy, especially during the germination period. Once the plants are well established, protect them from weeds by weeding regularly. Also remember to mulch around the plants to keep the soil moist and limit weeds.
White onions can be harvested around 3 months after sowing. Take care not to damage the bulbs when harvesting and leave them to dry in the sun before storing in a cool, dry place.
How do I plant white onions?
To grow white onions naturally, it's important to choose a sunny, well-drained location. The soil should be light, fresh and rich in organic matter. Before planting, it is advisable to work the soil deeply by carefully weeding.
White onions can be sown in the ground from February or transplanted from April. To sow, simply press the seeds in 1 cm deep, spacing them 10 cm apart. To transplant, the plants should be spaced about 10 cm apart and planted at a depth equivalent to their root ball.
Be sure to water the plants well after planting, but avoid over-watering to prevent rotting. It is also advisable to hoe regularly to prevent competition from weeds.
White onions are a good choice of planting material.
White onions can be harvested as early as summer when the tops start to yellow and dry out. It is best to harvest them in dry weather and let them air dry before storing them in a cool, dry place.
How to harvest white onions successfully?
White onions can be harvested in summer when the tops start to yellow and droop. To harvest them, simply pull the plants gently out of the ground. It's best to let the onions dry and harden for a few days before storing.
Harvested white onions can be stored for up to several months in a cool, dry, well-ventilated place. It is important to store them in a dark place to prevent them sprouting prematurely. We recommend hanging them in a net or placing them in wooden or paper boxes.
