when to remove fruit
When grapefruit is not ripe, must we remove it when the new blossoms come in?
I would not pick them before they are ready. Most citrus fruits, especially grapefruit, do not ripen once they are picked. In fact, grapefruits are best left on the tree awhile, as they will become sweeter. Grapefruit harvesting normally takes place in fall. When the fruits are yellow or golden in color, then they are ready for harvesting.
