What is a sugar apple tree?

The sugar apple tree (Annona squamosa), also known as sweety sapote or matasano, is a tropical evergreen tree native to tropical regions in the Americas. It grows variably sized, heart-shaped leaves and bears large, fragrant flowers that are pinkish in the center and white or cream on the edges.

The fruit of the sugar apple tree is called a sugar apple, or sweetsop. When ripe, sugar apples are soft and wrinkly with a thick, smooth, green skin. Inside is a segmented white flesh that ranges from dry to creamy or custard-like in texture. Each segment contains several large, dark-brown seeds.

Ripe sugar apples have a mildly sweet flavor that has been described as a cross between pineapple, peach, and banana. The fragrance and flavor make them a popular tropical fruit in areas where they grow. The trees tend to reach heights between 15 and 30 feet and will grow fruit year-round in tropical climates suitable for the plants.

Some key facts about this tree are:

  • Native to tropical regions of Central America, the Caribbean, and northern South America
  • Thrive in USDA hardiness zones 9โ€“11.
  • Prefers warm, humid conditions with abundant rainfall or irrigation
  • Moderately drought-tolerant when established
  • Reaches maturity and begins bearing fruit within 3-5 years

These are versatile landscape plants that also produce nutritious, exotic fruit enjoyed around the world. Their care and cultivation have been refined over centuries, making them a popular home orchard crop for warm climates.

Varieties of Sugar Apple Trees

Several varieties of sugar apple trees are commonly grown for their unique fruit attributes and adaptability traits:

Brooks Special

Vigorous trees bear elongated, medium-sized fruit with bright red skin when ripe. Creamy white flesh that’s sweet with few seeds. tolerant of various soil types.

Chapman

The old standard variety is known for heavy, consistent crops of large, round fruits up to 2 lbs each. Thick, sweet yellow-green flesh is the best flavor. More cold-sensitive.

Maravilla

Dwarf, self-pollinating trees stay under 10 feet. Fruits earlier than others, with red-blushed skin hiding sweet yellow flesh. Productive, compact variety for small spaces.

January

Fast-growing trees bear oblong, pink-skinned fruit year-round in the subtropics. Thick flesh resists bruising for shipping. Higher yields are more disease-resistant.

Neil

Less cold-tolerant trees are rewarded with very large, 2 lb. fruits. Thin green skin reveals soft pink segments of melting, richly flavored flesh.

Choosing varieties suited to your climate and the characteristics that are most important ensures productive sugar apple trees. Consider factors like tree size, flavor, and disease resistance. Talk to local nurseries and extension agents for customized variety recommendations.

Planting Sugar Apple Trees

The best time to plant these trees is during the rainy season or spring, when moisture is abundant, as they prefer constantly moist soil. Seedlings can be found at tropical fruit tree nurseries, while seeds may also be planted directly.

When choosing a planting location, select a spot with full sun exposure and deep, fertile, well-draining soil. Sugar apples prefer soil with a pH between 5.5 and 7.5. Improve clay soil by incorporating organic matter, such as compost.

Planting from Seeds

Sugar apple seeds can be started indoors 4-6 weeks before the last frost date if planted outside. Plant seeds 1/4 inch deep in the seed starting mix. Keep the mix moist at 70โ€“80ยฐF. Harden off seedlings before planting them outdoors. Do this after the threat of frost has passed.

For direct sowing, plant seeds 1/2 inch deep outdoors in the spring. Space 2-3 feet apart, as roots develop lateral surface runners. Expect a 60โ€“80% germination rate. Thin or transplant the strongest seedlings 18 inches apart once established.

Planting Seedlings or Grafted Trees

Dig a hole twice as wide as the root ball and slightly shallower than the root mass. Remove any containers or bags from around the roots. Set plants in the hole at the same level as they were growing.

Backfill with native soil, lightly tamping to eliminate air pockets as you go. Water thoroughly after planting. Apply 2-3 inches of mulch, such as bark or wood chips, to conserve moisture. Stake, if needed, for support.

Regular watering and protection from the sun and wind are important. Young trees need these while establishing themselves during their first year. Proper care at planting ensures apple trees get off to a healthy start.

Once established, these trees are low-maintenance crops that thrive with sufficient water, fertilizer, and pruning. Ongoing care helps maintain productive, long-lived trees.

Watering

Sugar apples require consistent moisture but not soggy soils. Water deeply 1-2 times per week, depending on rainfall. Allow the top inch of soil to dry slightly between waterings.

Irrigate more often during flowering, fruiting, and periods of heat and drought. Use soaker hoses or drip irrigation for efficient water delivery to the roots.

Fertilizing

Feed trees monthly during the growing season with a balanced fertilizer like 10-10-10. Increase to weekly applications if producing a heavy crop. Sugar apples also benefit from foliar sprays of fish emulsion or compost tea.

Mulch around the base each spring with organic matter like shredded leaves to enrich the soil as it breaks down naturally. Avoid mulch that accumulates directly against tree trunks.

Pruning

Prune out spindly, diseased, or damaged growth as needed. This maintains an open structure that allows airflow and sunlight penetration. Trees can be pruned into a rounded canopy or trained as a central leader.

Most pruning is done post-harvest in winter or early spring before new growth begins. Thin congested centers and remove any branches crossing or growing vertically. Proper pruning promotes vigorous, abundant flowering and fruiting.

Pest and Disease Management

Common sugar apple tree issues include scale, mealybugs, ants, and anthracnose disease. Monitor regularly for signs of stress or infestation. Practice good sanitation and remove fallen fruit and debris where pests may overwinter.

Neem oil or insecticidal soap sprays every 10โ€“14 days, as needed, can help manage minor issues. Severe problems may require foliar fungicides. Or, you may need to call in specialized help for diagnosis and treatment. Healthy trees are generally quite resistant to major issues.

FAQs

How long will it take until sugar apple trees bear fruit?

Most varieties will start flowering and fruiting within 3-5 years after transplanting, if conditions are suitable. Young trees focus energy on establishing roots and structure initially.

Do sugar apple trees need another tree for pollination?

No, many popular varieties like ‘Maravilla’ are partially to fully self-fertile. Others may yield more heavily with another nearby tree for cross-pollination, but they aren’t dependent on it.

What pests and diseases affect sugar apple trees?

Common issues include scale, mealybugs, leaf spot/anthracnose fungi, and squash bug damage. Careful watering, fertilizing, and foliage clean-up helps prevent stress and associated infestations.

How do I store harvested sugar apples?

Refrigerate unripe fruit to continue ripening for up to 2 weeks. Ripe sugar apples will last 1-2 days at room temperature or up to a week refrigerated if unbruised. Can also be frozen or preserved.
