Benefits of Proper Seed Spacing
✅ Healthier Plants – Avoid overcrowding, which can lead to competition for nutrients, light, and water.
✅ Maximized Yield – Ensure each plant gets enough space to grow and produce optimally.
✅ Efficient Use of Resources – Reduce seed wastage and use available soil efficiently.
✅ Pest and Disease Reduction – Adequate spacing improves airflow, reducing the risk of fungal infections.
✅ Easier Maintenance – Proper spacing allows for easier weeding, watering, and harvesting.
