How many years does it take for a pomelo tree to bear fruit from planting?

How many years must a pomelo tree be grown before it bears fruit? Seedling pomelo trees generally begin bearing fruit in 8-10 years, while grafted trees bear fruit in 4-5 years. One to two years after the first crop, they enter the full bearing period. Grafted trees on trifoliate orange rootstock at 5-7 years old yield 15-50 kg per tree, and at 8-10 years can reach 50-100 kg.
Pomelo tree does not bloom
If a pomelo tree does not bloom, first prune the branches and bend them outward, removing weak branches that consume nutrients. Second, check whether pests or diseases have occurred. Finally, pay attention to loosening the soil and applying fertilizer. It is recommended not to apply fertilizer directly under the trunk of the pomelo tree, but to apply it within a radius of several square meters around it.
Pomelo tree blooms but does not set fruit
When a pomelo tree produces many flowers but sets fruit with difficulty, you can girdle the pomelo tree at flowering time and then hand-pollinate it; the pomelo tree will then set fruit very easily.
1. Girdling: Girdling means using a small knife to cut through the bark around the trunk of the fruit tree in one ring, or in a spiral cut of one or two rings, taking care not to damage the xylem. Under normal circumstances, the fruit tree can heal in about ten days. The purpose is to concentrate nutrients into the flowers and fruit.
2. Hand pollination: Pomelo trees need cross-pollination for a high fruit-setting rate and sweet fruit. Although self-pollination can set fruit, the fruit-setting rate is low and the fruit is bitter. Hand pollination of pomelo trees can increase the fruit-setting rate and improve the quality of the pomelo.
