Watering and Weeding: Onions need consistent moisture, especially during bulb formation. Mulching around the plants can help to retain soil moisture and suppress weed growth. Ensure the soil is consistently moist but not waterlogged, as excessive moisture can lead to rot.
Harvesting Time: When the tops of the onions begin to yellow and fall over, it’s a sign that they are ready for harvesting. Gently lift the bulbs from the soil and allow them to cure in a warm, dry place for a few weeks before storing.
How to Store Onions: After curing, trim the tops and store the onions in a cool, dry, and well-ventilated area. Braiding or hanging them in a mesh bag can help maximize airflow and prevent rot. Proper storage can extend the shelf life of onions for several months.
Tips For A Successful Onion Harvest
When it comes to a successful onion harvest, selecting the right variety is crucial. Choose a variety that suits your climate and daylight availability. Thinning onions while they are still young encourages healthier bulbs as they have more space to mature. Ensure to practice crop rotation to prevent the buildup of pests and diseases in the soil. Controlling onion flowering is vital to encourage the energy to be focused on bulbing instead of flowering, leading to larger and tastier onions.
