I grow both cherimoya and a few trial soursop trees on the same San Diego property, so the comparison is not abstract. Annona cherimola, the cherimoya or custard apple, and Annona muricata, known as graviola, soursop, or guanabana, belong to the same family yet demand different climates, produce different fruit, and sell into different markets. On our Exotic Fruits and Vegetables plots, the second-year cherimoya trees set fruit about three weeks later than the nursery stock we bought in, while the soursop selections lag further and struggle with our cool nights.
Cherimoya fruit is heart-shaped or conical, usually weighing half a pound to two pounds, with skin marked by fingerprint-like depressions or soft scales. The flesh is white, smooth, and custard-like. Flavor combines banana, pineapple, and a light strawberry note with clean sweetness. Graviola fruit is larger, often three to ten pounds or more, covered in soft spines, and the white flesh is more fibrous and juicier with a sharper, tangy profile that leans citrus and pineapple.
Cherimoya needs roughly fifty to one hundred chill hours between thirty-two and forty-five degrees Fahrenheit and performs best in coastal Mediterranean climates. Graviola prefers consistently warm tropical lowland conditions and has little tolerance for temperatures near freezing.
In San Diego the difference shows up immediately. Cherimoya trees leaf out and flower reliably after our mild winters. Soursop trees drop leaves more readily after cool nights and set far fewer flowers unless protected.
Growing requirements that separate the two crops
Cherimoya spacing runs twenty to twenty-five feet on center. Soil should drain freely; sandy loam or decomposed granite with pH 6.5 to 7.5 works well. Mature trees tolerate brief dips to about twenty-six degrees Fahrenheit, though young growth burns near twenty-nine. Hand pollination is standard for commercial fruit set because the flowers are dichogamous.
Graviola needs warmer nights, higher humidity tolerance in some regions, and protection from any frost. Trees can reach similar heights but often produce larger individual fruit. Pollination can also be limiting, yet the plant is more at home in true tropical zones than in coastal California.
For cherimoya, deep watering every two weeks during active growth and a balanced 8-8-8 fertilizer every three months keep the canopy productive. Excess late nitrogen produces soft growth that is more frost-sensitive.
One concrete failure still guides my decisions. I planted three young soursop seedlings on a slight slope that collected cold air in 2021. A single night near twenty-eight degrees killed the tops and set the trees back a full season. Replacement plants and lost time cost several hundred dollars in materials and labor before I moved the survivors to a warmer micro-site near a south-facing wall.
Planting graviola in a cherimoya-suitable site without frost protection is the most common reason the trees fail to reach commercial size in Southern California.

Yield patterns differ as well. A well-managed cherimoya can produce one hundred or more fruits per mature tree with consistent hand pollination. Individual fruit weight averages five and a half to eighteen ounces, with occasional larger specimens. Graviola yields fewer fruits per tree in marginal climates, yet each fruit can weigh several times more when the plant is happy.
Fruit quality, price, and how each is used
Retail cherimoya currently sells between nine and sixteen dollars per pound in specialty stores and direct farm sales. A-grade local fruit often moves at eight to ten dollars per pound from the farm. Graviola, when available fresh, tends to command similar or slightly lower per-pound prices but is more often sold by the whole fruit because of its size. Imported frozen pulp is common for both, yet fresh local cherimoya retains a clearer flavor advantage in our market.
| Trait | Cherimoya (Annona cherimola) | Graviola / Soursop (Annona muricata) |
|---|---|---|
| Skin | Smooth to lightly scaled, no spines | Covered in soft spines |
| Typical fruit weight | 0.5–2+ lb | 3–10+ lb |
| Flesh texture | Smooth, custard-like | More fibrous, juicier |
| Flavor profile | Sweet, banana-pineapple-strawberry | Tangy, citrus-pineapple |
| Climate preference | Coastal subtropical, some chill | Warm tropical lowland |
| Frost tolerance | Brief light frost when mature | Very low |
Have you ever bought a large spiny fruit expecting the soft sweetness of cherimoya and instead found a sharper, more acidic pulp? That mismatch is the most frequent complaint when the two are confused at the market.
Preparation is similar in principle yet different in practice. Cherimoya is cut in half, seeds removed with the tip of a knife, and the flesh eaten with a spoon. Graviola requires more work to separate the fibrous sections from the core and spines. Both fruits have toxic seeds that must never be crushed or swallowed.
- Choose cherimoya when you want smooth, sweet, spoonable flesh with complex tropical notes.
- Choose graviola when you want larger volume, more juice, and a brighter acidic edge for drinks or frozen desserts.
- Match the plant to your actual winter lows rather than average daytime temperatures.
- Budget for hand pollination and careful packing with either crop if you plan to sell fruit.
Sensory detail is decisive. A ripe cherimoya opened on the cutting board releases a mild pineapple aroma and feels dense and cool under the spoon. Graviola flesh is wetter, more stringy between the fingers, and carries a sharper scent that some describe as citrusy.
In our climate the soursop trees require more frost protection and still produce fewer marketable fruits per year than the cherimoya blocks. The extra labor rarely pays for itself at current local prices.
- Cherimoya for dessert quality and coastal California production
- Graviola for tropical sites or juice and pulp markets
- Never interchange the two when recommending varieties to a new grower
- Always remove and discard all seeds from both fruits
Seeds of both species contain alkaloids that can cause severe gastrointestinal and neurological symptoms. The skin of cherimoya and the spines of graviola should also be discarded.
I once delivered a mixed box to a chef who expected only cherimoya. The presence of one large spiny fruit led to a long conversation about labeling and customer expectations. Clear naming on every box eliminated the problem and protected the premium price the cherimoya commands.

Which one belongs on your property or plate
For a San Diego or similar coastal site, cherimoya is the practical choice. It matches the chill hours, tolerates the occasional light frost, and produces fruit that sells readily at eight to sixteen dollars per pound. Graviola remains an interesting trial plant only where winter lows stay reliably above freezing and where the grower accepts lower and less consistent yields. Taste preference is personal, yet the growing realities and market prices favor cherimoya for most people in this climate. Choose the species that fits your winter temperatures first, then refine the variety within that species.
