Chayote

Chayote is found wild in the cool mountains of Central America where it was first domesticated by the Aztecs. It has become a very popular food in many parts of the tropics and subtropics, where it is widely cultivated, and also supplies medicines and is a source of fibre. Young leaves and stem tips, cooked as a vegetable, eaten like asparagus, is a good source of iron, carotene, thiamine, riboflavin and niacin.

Chayote requires high relative humidity (80-85%), annual rainfall of at least 1500-2000 mm (or irrigation) and average temperatures of 20-25 °C (with limits of 12-28 °C). It grows best at 300-2000 m altitude. It is susceptible to frost, drought and wind. The natural habitats of wild chayote are moist steep hillsides. The plant generally grows well in full sun, but some cultivars produce higher yields when grown in light shade. It grows best in a sheltered position in a well-drained, fertile, humus-rich soil. Prefers a pH in the range 5.5 - 7, tolerating 4.3 - 8.
