If you're looking to add a tropical twist to your garden,
growing a sugar apple tree (also known as Annona squamosa or custard apple) might be the perfect choice.
This exotic fruit tree is not only a beautiful landscape feature but also gives you delicious, creamy, sweet fruits that are loved by many.
Whether you're an experienced gardener or just starting out, this guide will walk you through everything you need to know about growing sugar apple trees, from planting to harvesting.
What Is a Sugar Apple Tree?
The
sugar apple tree is a small, deciduous tree native to tropical regions of the Americas. It belongs to the Annonaceae family, which also includes the cherimoya and soursop. This tree can grow up to 10–20 feet tall and features light green, elongated leaves and knobby, heart-shaped fruits with creamy white pulp inside.
The sugar apple is popular in many tropical countries for its sweet, custard-like flavor and nutritional benefits. It’s packed with vitamin C, potassium, magnesium, and dietary fiber.
Why Grow a Sugar Apple Tree?
There are several good reasons to consider growing a sugar apple tree in your backyard:
Delicious and nutritious fruit
Tropical aesthetic that adds charm to gardens
Low maintenance compared to many fruit trees
Suitable for container gardening
Attracts beneficial pollinators like bees and butterflies
And if you're someone who enjoys rare or unique plants, sugar apple is definitely a conversation starter.
Ideal Climate for Sugar Apple Tree
Before you start digging, it’s important to check whether your climate is suitable. Sugar apple trees thrive in tropical and subtropical climates. They grow best in USDA hardiness zones 9 to 11.
The tree prefers:
Full sun (at least 6–8 hours daily)
Temperatures between 25°C – 35°C (77°F – 95°F)
No frost or freezing temperatures, they’re not frost-tolerans
If you live in a cooler climate, don’t worry. You can still grow sugar apple trees in large pots or containers and bring them indoors during cold months.
How to Plant Sugar Apple Tree

To be able to produce a srikaya plant that grows well, there are several things that you need to pay attention to.
Below are some tips that you must do:
1. Choose the Right Spot
Pick a sunny location with well-draining soil. Sugar apple trees hate soggy roots, so avoid planting in areas where water pools after rain.
2. Soil Preparation
They’re not too picky but prefer slightly acidic to neutral soil (pH 6.0 to 7.5). You can improve poor soil by mixing in:
Organic compost
A bit of sand or perlite (for drainage)
Well-rotted manure
3. Seed or Sapling?
You can grow sugar apple trees from seed, but it may take 3–4 years to bear fruit. For faster results, buy a grafted sapling from a nursery.
4. Planting Instructions
Dig a hole twice as wide as the root ball.
Place the tree in the hole and backfill with soil.
Water deeply right after planting.
Add a layer of mulch (but not too close to the trunk) to retain moisture.
Caring for Your Sugar Apple Tree
Taking care of a sugar apple tree is fairly easy if you keep up with these basics:
1. Watering
Young trees need frequent watering, especially during dry spells. Once established, sugar apples are drought-tolerant, but they still appreciate deep watering once a week.
Tip: Let the soil dry out a bit between watering to avoid root rot.
2. Sunlight
Full sunlight is non-negotiable. Without enough sun, the tree won’t produce healthy fruits.
3. Fertilizing
Feed your sugar apple tree every 2–3 months with:
A balanced fertilizer (10-10-10) during early growth
A low-nitrogen, high-phosphorus blend when flowering/fruiting
You can also use compost tea or fish emulsion as natural boosters.
4. Pruning
Light pruning in late winter or early spring helps:
Remove dead or crossing branches
Shape the tree for better airflow and light penetration
Encourage new growth
Avoid heavy pruning, as it can reduce fruit yield.
5. Flowering and Pollination
Sugar apple trees produce greenish-yellow flowers that bloom in clusters. These flowers are usually pollinated by beetles, but in many gardens, natural pollination is not very efficient.
To increase your chances of getting fruit:
Try hand pollination using a soft brush
Gently transfer pollen from male to female flowers in the early morning
When and How to Harvest Sugar Apples
Patience pays off! Sugar apple trees generally start fruiting in 3–4 years if grown from seed, or sooner if grafted.
Fruits are ready to pick when:
The skin turns slightly yellow-green
The segments of the fruit start to separate
It feels slightly soft to the touch
Don’t wait until they fall off, as they may crack or spoil. Once harvested, sugar apples ripen quickly, perfect for enjoying fresh, in smoothies, or in desserts.
Common Pests and Problems
Like most plants, sugar apple trees have their share of garden foes:
Pests:
Mealybugs
Scale insects
Fruit borers
Aphids
Combat them with neem oil sprays or insecticidal soap.
Diseases:
Anthracnose (fungal spots on leaves and fruit)
Root rot (from overwatering)
Good airflow, proper spacing, and avoiding overhead watering help prevent most problems.
Growing Sugar Apple Tree in Pots
Limited space? No problem. Sugar apples do well in large containers (at least 18–24 inches wide and deep).
Tips for pot-grown sugar apple trees:
Use loose, well-draining potting mix
Place in full sun on a balcony or patio
Repot every 2–3 years as the roots grow
Fertilize regularly during the growing season
Container trees might stay smaller but can still fruit beautifully.
Final Thoughts
Growing a sugar apple tree is like bringing a piece of the tropics to your backyard. It’s relatively easy to care for, eye-catching, and the reward of sweet, creamy fruit makes it all worthwhile. Whether you grow it in the ground or a container, with a little sunlight, water, and love, your sugar apple tree will flourish.
