The soursop tree, scientifically known as Annona muricata, is a tropical evergreen prized for its large, distinctive fruit. This fruit is often called graviola or guanábana, and is recognizable by its spiky green exterior and white, fibrous pulp. Its flavor profile is a unique blend, often described as a mix of pineapple, strawberry, and citrus notes, which has driven global interest in its cultivation. Although native to the Americas, its appeal has led to its spread across the tropical world.
Native Origin and Primary Range
The soursop tree’s indigenous home lies within the tropical lowlands of the Americas. It is widely considered native to the Caribbean, Central America, and northern South America, where it naturally flourishes without human introduction. This primary range includes countries like Colombia, Venezuela, and Brazil in South America, as well as Mexico and Guatemala in Central America.
The tree is an established part of the landscape in the West Indies. In these regions, the tree grows both in the wild and on subsistence farms, having been cultivated for centuries.
Global Cultivation Regions
Beyond its native habitat, the soursop tree has been successfully introduced and is now widely grown commercially in tropical zones worldwide. Its introduction to Asia began via the Philippines, establishing major cultivation areas in Southeast Asia, including Indonesia and Malaysia.
Commercial cultivation also extends across various parts of Africa, such as Nigeria and Kenya, where the warm, humid climate is well-suited for its growth. Limited but notable production occurs in other tropical areas, including the Island of Mauritius and certain Pacific islands.
The main global suppliers of the fruit today include Mexico, Peru, Brazil, Ecuador, and Haiti. The tree is also grown for local consumption in places like southern Florida.
Essential Environmental Requirements
The successful cultivation of Annona muricata is strictly governed by specific environmental conditions, as the tree is highly sensitive to cold. It requires a truly tropical climate, generally thriving in areas with mean annual temperatures between 21°C and 32°C.
The tree has a low tolerance for cold; temperatures dropping below 5°C cause damage to its leaves and small branches. Temperatures below 3°C are often fatal, meaning it can only be planted outdoors in frost-free areas.
The plant also demands a humid environment, ideally with a relative humidity between 70% and 80%. It requires high rainfall, with optimal growth achieved with annual precipitation between 2,000 and 2,500 millimeters.
The tree requires deep, well-drained soil, as it is highly susceptible to root rot in waterlogged conditions. Ideal soil types are light textures such as sandy loam or loamy sand, which ensure proper aeration. A slightly acidic soil pH is preferred (5.5 to 6.5), and the soil needs a high organic matter content.
