Cultivation of Coffee

The Coffea plant is native to tropical Africa and Madagascar, and the modern version of roasted coffee has its origins in Arabia. During the 13th century, coffee was extremely popular with the Muslim community for its stimulant powers, which proved useful during long prayer sessions. In 1616, the Dutch founded the first European-owned coffee estate in Sri Lanka, then Ceylon, then Java in 1696.

The French began growing coffee in the Caribbean, followed by the Spanish in Central America and the Portuguese in Brazil. European coffee houses sprang up in Italy and later France, where they reached a new level of popularity. Soon after, coffee plants reached the US, and by the late 1800s, coffee had become a worldwide community.

The coffee plant needs ample rainfall to grow, and its temperature requirements vary depending on its type. Coffee crops grow very well in higher altitudes, but they are very vulnerable to frost. Coffee plants can grow on a wide range of soils, but sandy loam soil is ideal for its cultivation.
