The pomegranate tree is entering the critical phase of flowering and fruit set. Proper management during this period is essential for a healthy and productive harvest. Here are key practices to follow:
1. **Flower Thinning** – During the transition from bud to bloom, all bell-shaped flowers should be removed, leaving only tubular and gourd-shaped flowers. If gourd-shaped flowers are abundant, they should also be pruned, keeping only the most vigorous ones. It’s important to leave 3 to 5 strong vegetative shoots with over 100 leaves around each fruiting branch. This process should be repeated 2 to 3 times throughout the flowering season to ensure optimal energy distribution.
2. **Flower Retention** – To improve fruit set, apply foliar fertilizers and growth regulators during early and full bloom. Solutions such as 0.2% urea mixed with rare earth micro-fertilizer, 0.3–0.5% borax, 0.3–0.5% potassium dihydrogen phosphate, and 50–100 ppm gibberellin can significantly boost pollination success and fruit retention.
3. **Fruit Thinning** – The goal of fruit thinning is to balance fruit size and quality. In mid-June, remove small or underdeveloped fruits from double fruits, leaving only one large fruit per cluster. If the tree has insufficient fruit, it's better to skip thinning entirely so that remaining fruits can grow larger. Additionally, any diseased, infested, or deformed fruits must be removed and buried to prevent disease spread.
4. **Fertilization** – A well-timed application of fertilizer supports the tree’s needs during flowering and fruit development. Fertilizer type and quantity depend on the tree’s age. For fruit-bearing trees, apply 0.5 to 1.5 kg of compound fertilizer to enhance fruit set and weight. Mature trees should receive more phosphorus and potassium, while younger trees benefit from a balanced mix of nitrogen, phosphorus, and potassium.
5. **Branch Adjustment** – Remove any dense or weak shoots that appear in spring. Late spring and early summer sprouts should be completely eliminated to avoid overcrowding. Also, cut away upright branches and those affected by pests or diseases to maintain an open canopy and promote air circulation.
By following these steps, you can ensure your pomegranate tree produces high-quality fruit while maintaining its overall health and vigor.
