Many rural households have pomegranate trees planted in their yards, and there are also fruit farmers who cultivate pomegranate trees on a larger scale. To increase profits, it is necessary to reasonably improve the flowering and fruit setting rate. So, what's the issue when pomegranate trees don't flower?
1. Insufficient Sunlight: Pomegranate trees thrive in sunlight. Adequate sunlight promotes growth and flower bud differentiation. Therefore, during the intense sunlight of summer, they can also be grown under full sunlight.
2. Improper Watering: Throughout their growth process, pomegranate trees do not require a lot of water. Even during the growing season, keeping the soil slightly moist is sufficient. In summer, high temperatures lead to rapid soil moisture evaporation. Adhering to the "dry-wet alternating" principle is important; the potting soil should neither be too wet nor have standing water. When pomegranate trees develop flower buds, control the amount of watering and wait until the soil has dried out before watering again.
3. Lack of Nutrients or Excessive Nitrogen Fertilizer: Regardless of whether they are potted or planted in the ground, pomegranate trees need fertilization. Prolonged absence of fertilization or inadequate fertilizer supply weakens the tree, affecting flower bud differentiation. Conversely, excessive nitrogen fertilizer, despite promoting vigorous growth, may hinder flowering as nutrients are concentrated in the foliage. Pomegranate trees require rich soil; apply sufficient basal fertilizer during potting or planting, administer diluted fertilizer monthly during the growth period, supplement with phosphorus and potassium fertilizer after flower buds appear, and spray "Flower King 2" to promote flowering and enhance flower color. Reduce fertilization during flowering, and focus on phosphorus and potassium fertilizer after flowering to promote fruiting.
4. Lack of Pruning, Excessive Shoot Growth: During the growth period, remove excessive long shoots, weak branches, overly dense branches, and those that affect the tree's shape to increase ventilation and light penetration. This encourages nutrient concentration in the remaining branches, making them stronger and producing more flowers. Additionally, it promotes the sprouting of lateral branches.
In conclusion, if your pomegranate trees are not flowering, you can assess whether any of the above reasons apply to your situation and then treat accordingly.
