Grapefruit (Citrus paradisi) is a big, dense evergreen citrus tree you plant once and pick from for decades. You don't grow it from a pip — you plant a grafted tree: a chosen fruiting top joined onto a tough root variety called the rootstock. Of all the citrus, grapefruit needs the most steady heat to turn sweet, and it carries each crop the longest — 12–14 months from flower to ripe fruit. It does not sweeten one bit once picked, so it must ripen fully on the branch, and it is the most cold-tender of the common citrus: a hard frost can kill it. Orange, lemon, lime and mandarin are close cousins, each with its own guide.
