Care Guide | Annona
Annona is a group of tropical fruit trees known for their rich, custardy fruits and surprisingly manageable growth habits. From the creamy sweetness of sugar apple to the tangy complexity of Soursop, these plants bring a slice of the tropics right to your backyard. With proper care, a single tree can reward you with dozens of unique, heart-shaped or knobby fruits each season. Get ready—once you taste one, you’ll understand why these are often called “dessert fruits of the tropics.”
Characteristics
Annona plants are tropical to subtropical fruit trees that thrive in USDA zones 9–11 (some tolerate zone 8 with protection). They prefer warm temperatures, full sun, and well-drained soil. Most varieties grow as small to medium-sized trees, typically 10–25 feet tall, though they can be pruned to stay smaller.
These trees are moderately fast-growing and can begin producing fruit in 2–4 years, depending on the species and growing conditions. Annonas are woody trees with branching structures and seasonal leaf drop in cooler climates.
Many annona species benefit from hand pollination for improved fruit set, especially in areas without natural pollinators.
Popular Varieties
| Variety | Origin | USDA Zone | Height | Pollinator Needed? |
|---|---|---|---|---|
| Sugar Apple (Annona squamosa) | Tropical Americas | 9–11 | 10–20 ft | Often benefits from hand pollination |
| Atemoya (A. squamosa × cherimola) | Hybrid | 9–11 | 10–20 ft | Yes, for best yields |
| Cherimoya (Annona cherimola) | Andes Mountains | 9–10 | 15–25 ft | Yes |
| Soursop (Annona muricata) | Caribbean | 10–11 | 15–30 ft | No, but increased yield with multiples |
| Rollinia (Annona mucosa) | Amazon Basin | 10–11 | 15–25 ft | Yes |

Scientific Name
Annona plants belong to the Annonaceae family. This genus includes several fruit-bearing species prized for their soft, aromatic flesh. Common cultivated types include Annona squamosa (sugar apple), Annona cherimola (cherimoya), and Annona muricata (soursop).
Classification
Annonas are woody perennial trees or shrubs. They produce fragrant flowers that are often pollinated by beetles in their native habitat. In cultivation, especially outside the tropics, hand pollination is often necessary to ensure good fruit production.
USDA Hardiness Zones
Most annona species grow best in USDA Zones 9–11. Some, like cherimoya and atemoya, tolerate brief dips into the upper 20s°F but may defoliate. Soursop and rollinia are strictly tropical and will not tolerate frost. If you’re in a cooler area, container growing is a solid option so you can bring plants indoors during cold snaps.
Plants have a culture they prefer, just as people from various countries and households have their own customs and traditions. The U.S. Department of Agriculture created the USDA hardiness zone map to help gardeners identify the areas in which plants tend to grow well based on past average temperatures and climates.
Height Potential
Annona trees typically grow between 10–30 feet tall depending on the species. However, they respond well to pruning and can be maintained at 8–12 feet for easier harvesting and container growing.
Planting
Plant annonas in a sunny, warm location with protection from strong winds. Space trees 10–20 feet apart. They prefer slightly acidic, well-draining soil.
If growing in a container, choose a large pot with excellent drainage and plan to up-pot as the tree matures.
Light
Full sun is ideal—aim for at least 6–8 hours of direct sunlight daily. Inadequate light can lead to poor flowering and fruit set.
Soil/Watering
Annona trees require well-draining soil and are somewhat drought-tolerant once established. Water regularly during the growing season, but allow the soil to dry slightly between waterings. Overwatering can lead to root rot.
Fertilizer
Feed with a balanced fertilizer every 4–6 weeks during the growing season. Young trees benefit from higher nitrogen, while mature trees need more phosphorus and potassium to support flowering and fruiting. Micronutrients like magnesium and iron can be helpful, especially in sandy soils.
Pruning
Pruning is recommended to maintain shape, control height, and improve airflow. Annona trees can be trained into an open canopy, which helps with light penetration and fruit production. Remove dead, crossing, or crowded branches annually.
Cold Weather Care
Annona trees vary in cold tolerance, but most need protection below 32°F. Use frost cloths, mulch heavily around the base, or move container plants indoors. Defoliation during cold weather is normal for some species and not always a cause for concern. Learn more in our Overwintering Guide.
Fruiting and Harvesting
Annona fruits typically develop 3–6 months after flowering. Harvest when fruits soften slightly or show color change, depending on the species. Fruit does not ripen well on the tree—pick mature and allow to soften indoors for best flavor.
Common Pests
Watch for scale insects, mealybugs, aphids, and fruit borers. Neem oil and insecticidal soap are effective treatments. Keeping the tree healthy and well-pruned helps prevent infestations.
Toxic to Pets?
The flesh is edible, but seeds are toxic if ingested and should always be discarded. Keep fallen fruit cleaned up if pets are around.
After Arrival Care
Please give your plant a little TLC after its journey through the mail 📬. Here are a few steps we recommend:
- Unwrap immediately to provide fresh air to the plant and soil.
- Wait a few days before exposing to full sunlight so your plant can adjust.
- Always protect from heat and cold because temperature extremes can be stressful.
- Water thoroughly if the plant is dry.
- Grow out in a larger pot and transplant as roots establish.
Repotting
We highly recommend growing your baby plant out in a larger pot 🪴 to increase success. Repotting helps focus water and nutrients directly toward the roots.Start with a pot 1–2 inches larger than the current size. Transplant once roots reach the bottom.
