Long An boasts the largest concentrated lime growing area in the country, spanning over 11,500 hectares (up to 2025), ensuring the scale and supply capacity necessary for the international market. The superior quality of this product stems directly from the unique combination of natural conditions and specialized cultivation techniques applied in the geographical area: 1. Unique Terroir and Climate - Optimal Light & Heat: The region enjoys high average temperatures (26.3°C - 29.7°C) and long daily sun exposure (7 to 9.5 hours/day). This intensity stimulates the synthesis of chlorophyll, resulting in the lime's characteristic deep, dark green, uniform peel color and slower color transformation during ripening. - High Nutritional Value: The prolonged sunshine and high temperatures trigger the lime trees to synthesize higher levels of defensive compounds, resulting in elevated content of Vitamin C (37.3 – 40.5 mg/100g) and Organic Acids (6.6 – 7.8%). 2. Specialized Cultivation Techniques - Rich Soil Composition: The light-loam soil, a mix of sand, alluvium, and clay, has excellent water retention, aeration, and is rich in nutrients, including high organic matter and moderate acidity (pH 5.5 - 6.5). These soil properties are key to inhibiting peel color change, maintaining the lime's desirable deep green hue compared to other regions. - Specific Pruning & Organic Fertilization: Farmers apply specialized pruning techniques in the early rainy season to enhance air circulation and light reception across the fruit-bearing canopy. Additionally, the use of well-composted organic manure twice a year enriches the soil, boosting the NH4+ content which further contributes to the vibrant green peel color. - Early Harvesting Technique: Limes are harvested early, between day 120 and day 130 after flowering. This precise timing ensures the fruit is firm, has a thick segment membrane, and retains a high protopectin content, which maximizes fruit firmness and dramatically improves shelf life and shipping resilience. Importers can rely on the consistency and exceptional quality of Long An Seedless Limes—a product carefully engineered by nature and expert local hands to meet the highest global standards.
