Soil Preparation
Onions thrive in well-drained, fertile soil. Before planting, amend the soil with compost or manure to improve its structure and nutrient content. The ideal pH for onions is between 6.0 and 6.8.
Planting Time and Spacing
Onions can be planted in the spring or fall. Choose a sunny location with plenty of space for the onions to grow. Plant the onion sets or transplants 4-6 inches apart, with the pointed end up.
Fertilizing
Onions are heavy feeders, so they require regular fertilization. Fertilize the onions every 3-4 weeks with a balanced fertilizer.
Watering
Onions need consistent moisture but should not be overwatered. Water the onions deeply when the soil feels dry to the touch. Avoid getting water on the leaves, as this can lead to disease.
Weed Control
Weeds compete with onions for nutrients and water, so it’s important to keep them under control. Mulch around the onions to suppress weeds and retain moisture.
Mulching
Mulching around the onions helps to retain moisture, suppress weeds, and regulate soil temperature. Use a layer of straw, compost, or leaves as mulch.
Disease and Pest Control
Onions are susceptible to a few diseases and pests. Common diseases include onion smut, downy mildew, and pink root rot. Common pests include onion maggots, thrips, and aphids. Practice good sanitation and use organic methods to control pests and diseases.
Harvesting
Onions are ready to harvest when the tops start to turn brown and fall over. Gently lift the onions from the soil and allow them to cure in a warm, dry place for several weeks.
Storing
Proper storage is essential for preserving the quality of your onions. Store the onions in a cool, dry, and well-ventilated area. Onions can be stored for several months under the right conditions.
