Citrus — Orange, Lemon, Lime, Tangerine, Grapefruit
Citrus is such a vast subject that volumes have been devoted to this genus. It is rich in history, with varieties being cultivated as far back as 2000 BC in China and is now a billion dollar industry worldwide. Citrus can be grown from sea level to the upper slopes, each variety having its ideal growing area. In Hawaii with our tropical climate, expect oranges and tangerines to have a greenish tint to the skin and a tighter adherence of the peel to the fruit, making oranges and other citrus more difficult to peel than citrus grown in more temperate areas such as California. Citrus must be planted in a well-drained soil and requires regular fertilization with minor nutrients for maximum production.
