Soursop is a tree, a long-term addition to the landscape. It's hardy across USDA zones 10 through 12 and stands up to deer. Its summer flowers are a modest draw for native bees, even though the fruit is the prize. It roots deep, which helps it reach moisture in a dry spell and open up tight soil as it establishes.

What Soursop is
Soursop grows as a perennial and reaches around 20 feet at maturity. It blooms yellow in summer. It's also deer-resistant.
How to grow Soursop
Soursop grows in USDA zones 10 through 12. Soursop does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.5 to 8, on well-drained ground. It needs around 5,000 growing degree days to mature, a growing season of at least 180 frost-free days, and about 0 hours of winter chill to set fruit, which is why climate matters as much as soil.

Plant it right
Set soursop in full sun with well-drained soil. Many fruit trees need a second variety nearby to pollinate — check before you plant just one.
Match the soil
Soursop prefers pH 4.5 to 8 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Be patient, then harvest
Prune annually while the tree establishes; fruit trees reward patience with years of harvest. Local Extension guides publish per-cultivar bearing-age tables.
Where Soursop thrives
Soursop is hardy across USDA zones 10 through 12. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 10–12 spans average winter lows from 30°F to 60°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 8 down the middle — and which side of that line your land sits on changes the answer.

Where Soursop stands, state by state
Soursop is rated for zones 10–12 — a cold floor USDA puts at 30 to 40°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 8 more, and 43 sit outside it — and inside every split state, the same line runs on at county grain.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

Growing guides for soursop
In rotation planning, soursop counts as a Other — beds recover best when other crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)
Good to know
One caution for pet owners — soursop is toxic to dogs and cats (mild severity). Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: Cornell Poisonous Plants Database.)
Soursop offers low value to bees and other pollinators.
Before you harvest soursop, know your soil
Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant soursop for food. Our free screen reads 9 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.

How we know this about Soursop
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Soursop in my zone?
Soursop grows in USDA hardiness zones 10 through 12 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Soursop?
Set soursop out in early spring or fall while it's dormant, so the roots establish before the heat of summer. Your local last-frost date — which a Growable Ground report pulls for your exact address — sets the precise window.
How much sun does Soursop need?
Soursop needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Soursop need?
Soursop prefers soil pH 4.5 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Soursop attract pollinators?
Yes — soursop's flowers are a modest nectar source for native bees.
Is Soursop safe for pets?
Soursop is toxic to pets (dogs,cats) with mild severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: Cornell Poisonous Plants Database.)
