Onion
FACTS
Ancient Cultivation: Onions have been cultivated for over 5,000 years and are believed to have originated in central Asia. They were even worshipped by the ancient Egyptians, who considered them a symbol of eternity.
Varieties: There are many different varieties of onions, ranging in size, shape, and flavor. Some popular types include yellow onions, red onions, white onions, and sweet onions such as Vidalia onions.
Tear-Inducing Compound: Onions contain a sulfur compound called syn-propanethial-S-oxide. When you cut an onion, it releases this compound, which irritates the eyes and causes them to tear up. Chilling the onion before cutting can help reduce the release of this compound.

Health Benefits: Onions have several health benefits. They have anti-inflammatory properties, may help lower cholesterol levels, and may contribute to heart health. They also contain compounds that have antibacterial properties.
Long Shelf Life: Onions have a relatively long shelf life compared to many other vegetables. When stored properly in a cool, dry, and well-ventilated place, they can last for several weeks or even months.
Symbolism and Folklore: Onions have been associated with various symbolic meanings and folklore throughout history. They have been seen as a symbol of strength, endurance, and protection. In some cultures, onions were even believed to ward off evil spirits or have healing properties.
Onion Rings: The popular deep-fried snack known as onion rings is believed to have originated in the United States in the early 20th century. They are made by dipping sliced onions in batter and frying them until crispy.

Choosing Onion Varieties: Select onion varieties suitable for your climate and preferred taste. Some popular varieties include Yellow Sweet Spanish, Red Burgundy, White Lisbon, and Walla Walla.
Soil Preparation: Onions prefer well-draining soil with a pH level between 6.0 and 7.0. Prepare the soil by adding organic matter, such as compost or vermicompost, to improve its fertility and drainage.
Planting Time: Onions can be grown from seeds, sets (small bulbs), or transplants. The planting time depends on the type of onion and your location. Generally, onions can be planted in early spring or fall, depending on your climate.
Spacing: Follow the recommended spacing guidelines for your onion variety. Typically, onions should be spaced 10-15cm apart in rows, with rows spaced about 30-45cm apart. Proper spacing allows for adequate air circulation and bulb development.
Planting Depth: When planting onion sets or transplants, place them in the soil at a depth of about 3cm. If planting from seeds, sprinkle them on the soil surface and cover lightly with a thin layer of soil.
Watering: Onions require consistent moisture, especially during bulb development. Water the plants regularly, aiming for about 3cm of water per week. Avoid overwatering, as excessive moisture can lead to rotting.
Mulching: Apply a layer of organic mulch, such as straw or shredded leaves, around the onion plants. Mulching helps conserve moisture, suppress weed growth, and regulate soil temperature.
Fertilisation: Onions benefit from regular fertilisation. Apply our compost tea once a week during the growing season. Avoid excessive nitrogen, as it may result in lush foliage but smaller bulbs.
Weed Control: Keep the onion bed free from weeds, as they compete for nutrients and water. Regularly remove weeds by hand or use mulch to suppress their growth.
Harvesting: Harvest onions when the foliage begins to turn yellow and topple over. Gently loosen the soil around the bulbs and lift them out. Allow the onions to cure by drying them in a well-ventilated area with good air circulation. Once the outer skins are dry and papery, trim the foliage and store the onions in a cool, dry place.
Remember to check the specific growing recommendations for the onion variety you choose, as some varieties may have specific requirements. Happy gardening!
