Repurposing Sprouted Onions

When an onion sprouts, it’s a sign of life waiting to be nurtured. Instead of discarding it, take advantage of this opportunity to create fresh produce. The sprouted bulb houses the embryo of a new onion, ready to unfold its layers of flavor.

Preparing the Onion and Soil

Before planting, carefully remove the sprouted top from the onion. Then, choose a well-draining potting mix that is high in organic matter. Fill a pot or container with this mix, ensuring that it has drainage holes.

Planting and Watering

Plant the sprouted onion root side down about 2 inches deep into the soil. Water it well and place the container in a sunny location where it will receive at least 6 hours of sunlight daily. Keep the soil consistently moist but avoid overwatering.

Fertilizing and Harvesting

Once the onion plant has established, fertilize it every few weeks with a balanced liquid fertilizer. About 3 months after planting, the onion will begin to swell. Harvest the onion when its top has turned brown and dried out, and the bulb is firm to the touch.

Troubleshooting Common Issues

The key to healthy onion growth is preventing problems before they arise. Ensure adequate sunlight, avoid waterlogging, and watch for signs of pests or diseases. Act promptly if any issues occur to prevent setbacks to your onion patch.

• For continuous onion harvest, plant new sprouted onions every 2-3 weeks.
• Compost spent onion plants to enrich your soil and promote future growth.
