Preparing the Onion Sets

To grow onions from sets, start by selecting healthy onion sets from a reputable source, ensuring they are firm and disease-free.

Choose an appropriate planting location with well-draining soil and full sunlight.

Before planting, separate the onion sets and remove any dead or rotten parts.

It's advisable to soak the onion sets in water for 1-2 hours before planting to promote hydration.

Once they have soaked, plant the onion sets in the prepared soil, making sure to space them appropriately.

Cover the sets with soil, leaving the tips exposed.

Water the newly planted onion sets gently to settle the soil.

Caring for Onion Plants

Provide regular watering to keep the soil consistently moist but not waterlogged.

Onions require about an inch of water per week, either from rainfall or supplementary irrigation.

Apply a balanced fertilizer to the onion plants every 3-4 weeks to promote healthy growth.

Remove any weeds that compete with the onion plants for nutrients.

Mulching around the onion plants can help suppress weeds and retain soil moisture.

Be vigilant for signs of pests and diseases, such as onion maggots or fungal infections.

In case of pest or disease infestation, take appropriate measures based on organic gardening practices.

Regularly monitor the onion plants and provide support (e.g., stakes) if necessary.

Dealing with Common Onion Issues

Onions can be susceptible to certain issues like bolting, onion maggots, and fungal diseases.

To prevent bolting, choose onion varieties suited for your region and plant them at the appropriate time.

To manage onion maggots, use floating row covers or beneficial nematodes to deter their presence.

Fungal diseases can be controlled by ensuring proper air circulation, avoiding overhead watering, and removing infected plants.

In case of severe infestations or diseases, consult with a local agricultural extension office or gardening expert.

Harvest the onions when the tops have turned yellow and flop over. Allow them to dry for a couple of weeks before storing.
