Garlic Planting Guide
1. Site Selection:

- Soil: Prefers well-drained, light to medium soils with good organic matter content. Avoid compacted or excessively clayey soils.
2. Soil Preparation:
- Tillage: Perform deep tillage to loosen the soil and improve aeration.
- Amendments: Incorporate compost or organic fertilizer to enrich the soil. A pH between 6.0 and 7.5 is ideal.
- Fertilization: Apply balanced fertilizers based on the results of a prior soil analysis.
3. Clove Selection and Preparation:
- Planting Material: Use healthy, good-sized garlic cloves selected from mature, disease-free bulbs.
- Preparation: Carefully separate the cloves from the bulb, keeping the skin intact.
4. Planting Time:
- Season: Depending on the region, planting can be done in the fall (preferred in temperate climates) or early spring.
5. Planting:
- Depth and Spacing: Plant the cloves at a depth of 2-3 cm, with the tip facing up. Leave a distance of 10-15 cm between plants and 30-40 cm between rows.
- Initial Watering: Water well after planting to ensure good contact between the cloves and the soil.
6. Crop Management:
- Irrigation: Maintain uniform soil moisture, avoiding waterlogging. Reduce watering in the final weeks before harvest.
- Weed Control: Regularly control weeds to avoid competition for nutrients and light.
- Continuous Fertilization: Apply additional fertilizers during growth stages as needed.
7. Pest and Disease Control:
- Common Pests: Monitor for pests such as the garlic weevil and onion fly. Use traps and biological treatments when necessary.
- Diseases: Practice crop rotation and apply specific fungicides to control fungal diseases such as rust and downy mildew.
8. Harvest:
- Maturity Indicators: Harvest is done when the lower leaves begin to dry, typically 90-120 days after planting.
- Harvesting Method: Carefully extract the bulbs using a fork or spade, avoiding damage to the bulbs.
9. Post-Harvest:
- Drying: Place the bulbs in a ventilated, shaded area to dry for 2-3 weeks.
