• Enrich the soil with aged compost or organic matter for optimal nutrient retention.

3. Care and Maintenance

• Sunlight: Requires full sun (at least 6-8 hours daily).

• Mulching: Helps retain soil moisture and suppress weeds.

• Fertilizing: Apply a low-nitrogen fertilizer every 3-4 weeks.

4. Harvesting Ruby Red Onions

• Time to Maturity: 100-120 days from planting.
