Generally, grapefruit seedlings begin to bear fruit in 8- 10 years, and grafted trees bear fruit in 4-5 years. After the first fruiting, 1-2 years entered the full fruiting stage, and the output of 5-7-year-old grafted trees15-50kg, and it could reach 50- 10 years in 8-/kloc-0 years.

First, pomelo trees don't bloom.

If pomelo trees don't bloom, we should first prune and pull branches, remove weak branches that consume nutrients, then check whether there are pests and diseases, and finally pay attention to loosening the soil and fertilizing. It is suggested that fertilization should not be applied under the trunk of grapefruit, but within a few square meters around it. You can also choose topdressing Woye granular water-soluble fertilizer.

Second, pomelo trees bloom without fruit.

Many pomelo trees bloom, but they are not easy to bear fruit. You can circumcise the pomelo tree when it blooms, and then pollinate it artificially, so that the pomelo tree can bear fruit easily.

1. Ring cutting: Ring cutting is to cut the bark of the trunk of a fruit tree with a knife or a gong without damaging the xylem. Generally, fruit trees can be cured in about ten days, so that nutrition can be concentrated on flowers and fruits.

2. Artificial pollination: pomelo trees only have high fruit setting rate and sweet fruit after cross pollination. Although self-pollination can bear fruit, the fruit bearing rate is low and the fruit is bitter. Artificial pollination of pomelo trees can improve the fruit setting rate and quality of pomelo.
