The grapefruit is a man-made cross between the pummelo and sweet orange. Grapefruit trees are widely grown in California, Arizona, Texas and Florida, with Texas alone raising more than a million tons of fruit annually.
Grapefruit trees generally bear a crop each year. The fruit first matures in late October and continues to grow until May. Grapefruits can be picked any time between these months.
Most grapefruit trees do not produce any fruit during the first two or three years after transplanting and take up to five years to grown from seedling to fruit-bearing tree. Any fruit developing before this should be picked early to allow the tree to focus its energy on growth.
Fruit Per Tree
A grapefruit tree's first crop often amounts to as much as 25 lbs. of fruit. This quantity will usually increase each year, reaching 250 lbs. around the tenth year of bearing fruit.
