Where Do Soursop Trees Grow? Climate, Regions and Leaf Origins

Soursop trees grow best in warm, humid tropical regions, but the species is now cultivated far beyond its original native range. That helps explain why soursop fruit and dried soursop leaves may come from places as different as Central America, the Caribbean, Southeast Asia and tropical Africa.

This guide covers the native range of Annona muricata, where it is cultivated today, the climate and soil conditions it prefers, where it can grow in the United States, and how the geographic origin of dried soursop leaves may differ from where those leaves are later processed or packaged.

What Is Annona muricata? Names, Tree and Leaves

Annona muricata is the accepted botanical name for soursop. Kew places the species in the genus Annona and the Annonaceae family.

The Annonaceae is often called the custard apple family. Other Annona species include the sugar apple (Annona squamosa).

Soursop is known by several regional names:

• Soursop in English
• Guanábana in many Spanish-speaking regions
• Graviola in Brazil and some international markets
• Corossol in some French-speaking regions
• Sour sack in some local English usage

These names generally refer to the same species rather than different trees.

A mature soursop tree develops a spreading canopy with glossy, dark green leaves. The tree produces both the familiar green fruit and the leaves that may later be harvested and dried for herbal tea.

The fruit is commonly eaten fresh in regions where it grows, while leaves may be collected and processed separately. For a closer comparison of the two plant parts, see soursop leaves vs. soursop fruit.

Native Range of the Soursop Tree

A native range describes where a species occurs naturally, rather than places where it was later introduced through cultivation.

Kew lists native occurrence of Annona muricata in areas including:

• southeastern Mexico
• Belize
• Guatemala
• Honduras
• Nicaragua
• Costa Rica
• Panama
• Colombia
• Venezuela
• Ecuador
• Peru
• Bolivia

Southeast Asia and many Pacific islands are therefore important modern growing regions, even though they are outside the species' original native range. This is a botanical and geographic distinction rather than an indication that fruit or leaves grown in those regions are of lower quality.

Soursop's present-day cultivation range is much larger than its native range.

Where Is Soursop Cultivated Today?

People have carried Annona muricata well beyond its original American distribution. It is now established across many tropical regions and some exceptionally warm subtropical areas.

Caribbean and Latin America

Soursop is widely grown throughout the Caribbean and tropical parts of Latin America.

Cultivated or introduced populations occur in places including Jamaica, Dominican Republic, Puerto Rico, Trinidad and Tobago, Cuba, Brazil, Mexico and other tropical areas of Central and South America.

Trees may be found in commercial orchards, small farms and home gardens.

Tropical Africa

Soursop has also become established in tropical parts of Africa.

Kew records introduced occurrence in countries including Benin, Cameroon, Gabon, Gambia, Guinea, Guinea-Bissau, Senegal and the Central African Republic, as well as Indian Ocean islands such as Mauritius, Réunion and Seychelles.

These areas share the warm temperatures, moisture and generally low frost risk that suit the species.

South and Southeast Asia

Soursop is cultivated in several parts of South and Southeast Asia.

Kew records introduced occurrence in areas including India, Bangladesh, Thailand, Laos, Vietnam, Indonesia, Taiwan and southern China.

Thailand is particularly relevant to PUREXA because its whole dried soursop leaves are sourced from Northeast Thailand.

Pacific Islands and Australia

Soursop also grows across numerous tropical Pacific islands.

Kew records introduced populations in the Cook Islands, Vanuatu, Marshall Islands, Marianas, Nauru and Queensland, Australia, among other locations.

Its broad distribution shows how successfully the species has spread through tropical cultivation.

What Climate Do Soursop Trees Need?

Kew classifies Annona muricata primarily within the wet tropical biome, which reflects its preference for warmth, adequate moisture and little or no frost exposure.

A 2026 University of Florida IFAS guide lists an optimum growing-temperature range of approximately 68–86°F (20–30°C) for guanábana and a mature-tree freeze-damage range of approximately 30–32°F (-1 to 0°C). The same guide classifies the tree as intolerant of constant winds.

These numbers are useful horticultural guidelines rather than hard biological boundaries. Tree age, microclimate and the duration of exposure also matter.

Temperature and Frost Sensitivity

Soursop is highly sensitive to cold.

Freezing temperatures can severely injure or kill the tree, especially when it is young. Prolonged cool weather may slow growth even before temperatures reach freezing.

Cold conditions can affect foliage, branches, young trees, flowers and developing fruit. This sensitivity is one of the main reasons outdoor cultivation is limited in cooler climates.

Rainfall, Humidity and Soil Moisture

Soursop is associated with humid tropical environments and generally performs best where moisture is reasonably consistent.

A 2024 scholarly review of soursop's climatic and soil requirements identified approximately 70–80% relative humidity and 2,000–2,500 mm of annual rainfall as optimal baseline conditions in its literature synthesis.

These figures are better viewed as suitability ranges than strict requirements. Trees can also grow under different rainfall patterns when irrigation, drainage and local conditions compensate.

The practical goal is consistent soil moisture without waterlogging. Poor drainage can contribute to root rot, while prolonged dryness may stress the tree and contribute to leaf drop.

Full Sun and Air Circulation

Soursop trees generally perform best with strong sunlight.

Persistent strong wind can damage foliage and branches. University of Hawai‘i guidance also describes the tree as susceptible to strong winds and notes the use of windbreaks in orchards.

Good air movement is still useful in humid conditions. Light pruning may be used to remove dead or damaged branches, reduce excessive crowding and improve air circulation.

Soil and Drainage

Soursop can tolerate several soil types, but good drainage is particularly important.

A 2024 review identifies highly suitable soils as well-drained and deep, with textures including loam, sandy loam and loamy sand. It places favorable soil pH around 5.5–6.5.

University of Hawai‘i guidance similarly states that soursop performs best in well-drained sandy soil with a pH around 5–6.5.

University of Hawai‘i CTAHR — Soursop

Common horticultural guidance therefore favors:

• well draining soil
• fertile loamy soils or sandy loams
• slightly acidic conditions
• adequate organic matter
• consistent but not excessive moisture

For container growing, a large container with drainage holes and a well draining potting mix is preferable to dense soil that remains saturated.

Mulching and the Root Zone

Soursop has a relatively shallow root system, so mulching can help conserve soil moisture and moderate conditions around the root zone.

There is no need to follow a universal rule such as “mulch exactly twice per year.” The appropriate amount and timing depend on rainfall, soil conditions and how quickly the mulch breaks down.

Elevation and Landscape

Soursop is most strongly associated with warm lowland and moderate-elevation tropical environments.

University of Hawai‘i guidance reports that the tree can grow from sea level to elevations above 3,000 feet in tropical conditions.

Elevation itself is not the deciding factor. Temperature, frost exposure, moisture and sunlight become increasingly important as elevation rises.

How Long Before a Soursop Tree Produces Fruit?

Fruiting age provides useful context for what successful cultivation can look like under suitable conditions.

University of Hawai‘i horticultural guidance reports that soursop grows quickly and may produce its first crop within approximately three to five years from seed.

Exact timing varies with planting material, climate and growing conditions, so fruiting age should not be treated as a guarantee.

Where Does Soursop Grow in the United States?

Because soursop is highly frost-sensitive, outdoor cultivation in the United States is limited to the warmest areas.

South Florida

South Florida provides some of the best conditions for outdoor cultivation in the continental United States.

Warm areas of Miami-Dade County and the Florida Keys can offer the heat and long growing season soursop prefers.

Even there, occasional cold weather can damage trees, so local microclimate and protection still matter.

Hawaii

Hawaii provides another suitable U.S. environment.

Warm tropical conditions allow soursop to grow in home gardens and agricultural settings, and University of Hawai‘i CTAHR maintains dedicated horticultural guidance for the crop.

USDA Zones and Other Warm Locations

Reliable outdoor cultivation is generally associated with the warmest U.S. climates.

Some horticultural sources describe Zones 10–11 as the most dependable range, while protected warmer microclimates outside that range may occasionally support cultivation.

USDA zones alone should not be treated as a guarantee because they primarily reflect minimum winter temperatures rather than every aspect of local climate.

Exceptionally warm pockets of coastal Southern California or far southern Texas may support protected cultivation, but conditions are less consistently suitable than South Florida or Hawaii.

In cooler climates, gardeners sometimes grow young soursop trees in containers so they can be moved indoors or into a greenhouse when cold weather arrives.

Container growing can help protect a tree from winter temperatures, but keeping a soursop tree alive in protected conditions is easier than providing the warmth, light and humidity needed for vigorous mature growth and reliable fruiting.

Where Can Dried Soursop Leaves Come From?

Dried soursop leaves used for tea may originate from many tropical regions where Annona muricata is cultivated.

Commercial sources can include parts of:

• Latin America
• the Caribbean
• tropical Africa
• South Asia
• Southeast Asia
• Pacific regions

Kew's distribution data show that the species is established in many countries outside its native range, including Thailand, Vietnam, Jamaica, Puerto Rico, India and numerous African and Pacific locations.

Geographic origin can be useful information, but it is only one part of evaluating a dried botanical product. Leaf condition also depends on harvesting, drying, moisture control, storage and packaging.

No single geographic origin automatically makes dried soursop leaves better. Suitable growing conditions and the way leaves are harvested, dried, stored and packaged are separate considerations from whether a growing region lies inside or outside the species' native range.

For a deeper product-quality discussion, see how to identify quality dried soursop leaves.

Origin vs. Processing vs. Packaging

Botanical products may involve several different locations.

Native Origin

This describes the natural geographic range of the species.

For Annona muricata, that range lies in the tropical Americas.

Agricultural Origin

This describes where the particular trees or botanical material used in a product were grown or sourced.

Leaves may therefore be sourced from Thailand even though Thailand lies outside the species' native range. This does not make those leaves botanically inferior; it simply means the crop was cultivated in a region where the species was introduced.

Processing or Packaging Location

After harvest, leaves may be dried, sorted, processed or packed somewhere else.

When agricultural origin matters, wording such as “grown in” or “sourced from” is more informative than a company address or packing location.

For more detail on botanical names, ingredient statements and product formats, see the soursop tea ingredients and label guide.

Example: PUREXA's Northeast Thailand Leaf Origin

PUREXA's whole dried Annona muricata leaves are sourced from Northeast Thailand.

Thailand is outside soursop's native American range, but Kew lists it among the areas where the species has been introduced.

Northeast Thailand is therefore a modern cultivation region for soursop, while the species' botanical native range remains in the tropical Americas.

The sourcing statement is useful for transparency, but it does not imply that Thai-grown leaves are inherently stronger, safer, better or worse than leaves from another suitable growing region.

How to Check Leaf Origin When Buying Dried Soursop Leaves

If geographic origin matters to you, look for information that clearly describes where the botanical material was grown or sourced.

• Look for a stated country or region of origin.
• Distinguish “grown in” or “sourced from” from “packed in.”
• Do not assume a company's business address identifies the growing location.
• Check the manufacturer's product page if package wording is limited.
• Ask the seller when agricultural origin is unclear.

Specific sourcing information can improve transparency, while product condition still depends on factors such as drying, moisture control, storage and packaging.

Frequently Asked Questions About Where Soursop Trees Grow

Can soursop trees grow outside the tropics?

Sometimes, but only in very warm subtropical conditions. The tree is highly sensitive to frost and freezing temperatures, so outdoor cultivation is most reliable in tropical or nearly tropical environments.

Where is soursop native?

Kew identifies Annona muricata as native from southern Mexico through Central America into parts of tropical South America. Its cultivation range now extends through many tropical regions worldwide.

Does being grown outside its native range make soursop inferior?

No. Native range describes where a species occurs naturally. Soursop is now successfully cultivated in many tropical regions outside its original range, and being grown in an introduced region does not by itself indicate lower quality.

Are soursop, guanábana, graviola and sour sack different trees?

No. These are regional common names for Annona muricata.

Is soursop related to custard apple and sugar apple?

Yes. Soursop belongs to the Annonaceae family and the genus Annona. Sugar apple (Annona squamosa) is a related species, but it is not the same plant.

Can soursop grow in Florida?

Yes, especially in the warmest parts of South Florida where frost risk is low. Cold snaps can still damage young or established trees.

Can you grow a soursop tree indoors?

Young trees can be kept in containers and moved into protected conditions during cold weather. Long-term indoor cultivation can be difficult because soursop naturally prefers strong light, warmth and humidity.

Does soursop grow in Southeast Asia?

Yes. Although the species is native to the tropical Americas, it is now established in Southeast Asian locations including Thailand, Laos, Vietnam and Indonesia.

How long does a seed-grown soursop tree take to fruit?

University of Hawai‘i guidance reports that a soursop tree may produce its first crop within approximately three to five years from seed under suitable conditions. Climate, sunlight, moisture, pollination and general tree health can influence actual timing.

Where do commercially sold dried soursop leaves come from?

They may come from several tropical growing regions, including Southeast Asia, the Caribbean, Latin America and tropical Africa. The actual source depends on the brand and supplier.

Is one country considered the best source for soursop leaves?

No single country is automatically superior based on geography alone. Growing conditions, harvesting, drying, storage, moisture control and packaging all affect the condition of the finished leaves.

Key Takeaway

Soursop (Annona muricata) originated in the tropical Americas but is now cultivated across much of the tropical world, including the Caribbean, Africa, South and Southeast Asia, Pacific islands and northern Australia.

The tree prefers warm conditions, reliable moisture, well draining soil and protection from frost. Research reviewing its climatic and soil requirements identifies favorable conditions including approximately 70–80% relative humidity, 2,000–2,500 mm annual rainfall and soil around pH 5.5–6.5, while local conditions still matter.

In the United States, South Florida and Hawaii provide the most dependable outdoor environments.

A region does not need to be part of soursop's native range to provide suitable cultivation conditions. Native range describes botanical origin; it does not establish a quality hierarchy among modern growing regions.

For dried leaves, geographic origin tells you where the crop came from, but it may not tell you where the product was later processed or packed.

PUREXA's whole dried soursop leaves are one example: they are sourced from Northeast Thailand, a modern growing region for a species whose native range lies in the tropical Americas.

Knowing the difference between native range, growing origin and processing location makes product labels and sourcing information much easier to interpret.
