My Grapefruit tree is producing "clusters" which causes problems when the Grapefruit grow. They damage each other before they are ready to harvest. Can I selectively remove some to give the others more space?

It is normal for grapefruit trees
to fruit in clusters. It is this fruiting habit which caused Citrus paradisi
to acquire its common name.
How many fruit the clusters consist of varies widely not only from 1 variety to the next but from cluster to cluster on the same tree.
My white grapefruit tree fruits singly and in small clusters or 3-4 fruits. My next door neighbor's pink grapefruit tree only produces heavy clusters of 12-20 fruits each.
I harvest and eat fruit from his tree each year (with my neighbor's permission, of course) and am very familiar with the tree.
Both of our tree's fruiting habits are perfectly normal and the crowded clusters have never caused damage to his fruit. He has never thinned the fruit.
I have noticed that his tree does produce many smaller fruits. I believe this may be a result of the fruit developing in such large clusters.You can thin the fruit to 1 every 6 inches, if you like. The remaining fruit should grow larger as a result.
I do not know if thinning will solve the problem you are having but it will not harm the tree in any way.
