Soil and Sunlight
To cultivate mandarin oranges successfully, start with fertile, well-drained soil with a slightly acidic pH. These sun-loving trees thrive in full sunlight. Proper soil preparation ensures optimal nutrient absorption and root development. Additionally, consider incorporating organic matter into the soil to enhance its structure and fertility.
Feeding and Spacing
Maintain your mandarin orange tree by feeding it twice a year with a balanced organic fertilizer. Spread the fertilizer over the root zone, allowing the nutrients to reach the entire plant. Adequate spacing is crucial for healthy growth. Single plants should be 19’ 8″ (6.00m) apart, and rows should have a minimum gap of 19’ 8″ (6.00m). This spacing allows for efficient air circulation and minimizes competition among neighboring trees. Proper spacing promotes individual tree health and contributes to a harmonious orchard layout.
Planting Techniques
For optimal growth, graft better mandarin orange cultivars onto sour orange rootstocks. When setting out purchased plants, position the root ball 1 inch (2 cm) above the soil line. Water deeply every ten days during dry spells. Mandarin oranges are self-fertile, making them suitable for single-specimen cultivation. In colder climates, container planting allows for indoor winter protection. Choose the largest planter you can manage to accommodate the root system. Remember to bring the potted tree indoors during winter to prevent frost damage.
Harvesting and Care
As mandarins ripen, their color turns bright orange. Sample large fruits for flavor, and harvest them before they fall to the ground. To avoid damaging the delicate rinds, clip the fruits from the tree using sharp pruning shears. Store harvested mandarins in a cool place to maintain their freshness and flavor. Regularly inspect the tree for signs of pests or diseases. While root rot diseases and leaf miners can affect mandarin oranges, homegrown plants often overcome minor issues. Vigilance and proper care contribute to a thriving citrus harvest.
