Reasonable pruning is good for the fruiting as well as the growth of the pomelo tree, and the next step is to introduce the pruning of pomelo trees at each stage:

1. Pruning during the seedling stage: After the pomelo tree seedling has been planted, the main trunk will be determined by making a cut 35 centimeters away from the grafting opening. Then when the grapefruit tree grows shoots, three vigorously growing, evenly distributed and widely spaced shoots are selected as the main branches, and the excess branches are cut off. When the main branches grow to about 40 centimeters, do a good job of centering and cut off the top branches and leaves. Then choose about 3 branches that grow vigorously around the main branch to stay as side main branches. The side main branches left behind should be distributed hierarchically on both sides of the main branch and the main branch and the side main branch to maintain a certain interval between them, to avoid shading, affecting the light, resulting in uneven light.

2, the result of the period of pruning: pomelo tree in the result of the time, is generally close to the main trunk inside the branches of the fruit ability is stronger. So for the first fruit trees, pruning should be light, not heavy pruning. Usually only need to prune some growth position is not right or grow too long branches and branches with pests and diseases, to retain more branches, and it is best not to prune the mother branch so as not to affect the results. In the case of mature trees, since the crown is well established, there is no need to prune the main crown too much, but only the lateral and other branches on the main trunk branches. The main purpose of this pruning is to ensure a balance between the growth of the pomelo tree itself and the growth of the pomelo fruit. For branches and leaves grow too luxuriant pomelo tree can be appropriate pruning heavier, so as to avoid nutrient imbalance, resulting in weak pomelo fruit.

3, the aging period of pruning: when the pomelo tree began to enter the aging period, should be in the spring before and after the growth and May-June time for pruning. To bare bone pruning mainly, that is, in the growth of new branches, to retain the appropriate amount of main branches and secondary main branches. Lateral branches that have grown within 4 years should be cut off from the crown, and no leaves should be kept in the crown to ensure the growth of strong tips. Then, after the buds have grown, the tree will be de-budded and controlled. It takes about two years for a new crown to form, and then the tree can bear fruit again. Finally, for some of the fruit but very old branches, can be appropriate rotation pruning renewal, in three years can make the aging branches all pruning renewal completed

The above is about the content of the pomelo tree pruning it, I hope to be able to help you.
