A Complete Central Florida Sugar Apple Growing Guide
Sugar apple is one of the most delicious and unusual tropical fruits you can grow.
Also called sweetsop or custard apple, sugar apple produces a soft, creamy fruit with naturally sweet tropical flavor. The fruit can be eaten fresh or used in desserts, drinks, sauces, and other recipes.
But growing sugar apple in Central Florida requires more planning than growing some of the hardier tropical fruit trees.
Sugar apple is particularly sensitive to freezing temperatures, and young trees can be severely damaged by cold. A warm, protected planting location is therefore one of the most important decisions you can make.
The good news is that sugar apple can be an attractive, manageable backyard fruit tree when given the right conditions.
This guide covers how to grow sugar apples in Florida, including varieties, planting, propagation, fertilizer, watering, pruning, flowering, pollination, cold protection, harvesting, pests, and the potential for selling your crop.

Can You Grow Sugar Apples in Central Florida?
Yes, but location is extremely important.
Sugar apple is a tropical tree and is much better suited to warm, frost-free areas than locations that regularly experience freezing temperatures.
Central Florida can be challenging because winter temperatures can occasionally fall low enough to damage or kill young sugar apple trees.
UF/IFAS reports that unprotected young sugar apple trees can be severely damaged or killed at approximately 30–32°F. Mature trees have somewhat greater cold tolerance, but sugar apple should still be treated as a cold-sensitive tropical fruit tree.
For Central Florida growers, look for the warmest microclimate on your property.
A protected location near a house, wall, fence, or other structure can sometimes provide useful protection from cold winds.
Avoid low areas where cold air settles.
And avoid locations that remain wet after heavy rain.
If your property regularly experiences hard freezes, growing sugar apple may require substantial winter protection or may not be practical in an exposed location.

What Is a Sugar Apple?
Sugar apple is Annona squamosa, a tropical fruit tree in the custard-apple family.
It is also known as:
– Sweetsop
– Custard apple
– Sugar apple
– Annon
The fruit has a distinctive segmented appearance.
When ripe, the segments separate somewhat and reveal creamy white flesh surrounding seeds.
The flavor is sweet and aromatic, often described as a combination of tropical fruit, vanilla, pear, and custard-like flavors.
Sugar apple is commonly eaten fresh with a spoon.
It can also be used in:
– Smoothies
– Ice cream
– Desserts
– Puddings
– Sauces
– Fruit salads
– Drinks
– Pastries
– Vegan desserts
The creamy texture makes sugar apple particularly interesting for recipes.

Best Sugar Apple Varieties for Florida
There are several sugar apple selections available to Florida growers.
UF/IFAS identifies several selections, including:
Thai Lessard
Thai Lessard is a green-skinned type and is one of the better-known sugar apple selections for Florida.
The fruit is generally larger than some other selections and is highly regarded for quality.
Kampong Mauve
Kampong Mauve produces purplish or reddish fruit.
It is a popular selection for growers who want a different appearance while retaining the characteristic sweet sugar apple flavor.
Purple or Red
Purple or Red sugar apples produce dark reddish-purple fruit.
The unusual color can be attractive for backyard growers and potentially useful when selling specialty fruit directly to customers.
Cuban Seedless / Brazilian Seedless
Seedless types have been introduced over the years, but UF/IFAS notes that these types have problems with fruit splitting as they approach maturity and generally have inferior fruit quality and yield compared with seedy types.
For that reason, UF/IFAS recommends green or red types for home landscapes.
Choosing a Variety
When selecting a sugar apple, consider:
– Fruit color
– Fruit size
– Flavor
– Seed content
– Tree availability
– Local performance
– Cold exposure at your property
– Whether you want fruit for home use or selling
If possible, buy a tree from a reputable nursery where the cultivar is known.
—
Where Should You Plant a Sugar Apple Tree?
Site selection may be the single most important decision for a Central Florida sugar apple.
Choose the warmest practical location on your property.
Look for:
– Full sun
– Excellent drainage
– Protection from cold winds
– Protection from strong winds
– Adequate irrigation
– Plenty of room for the tree
– Easy access for harvesting
Sugar apples perform best in full sun.
Shading from larger trees or buildings can reduce growth and fruit production.
UF/IFAS recommends planting sugar apples at least 15–20 feet from nearby trees, structures, and power lines when allowing the tree to develop normally.
For a backyard tree, however, regular pruning can be used to maintain a smaller, more manageable canopy.
—
How to Plant a Sugar Apple Tree
Start with a healthy nursery tree.
Avoid purchasing a large tree that has been left in a container that is too small for its root system.
A severely root-bound tree can have difficulty establishing after planting.
Step 1: Choose the location
Find a sunny, warm, well-drained area.
Step 2: Prepare the planting area
Remove grass and weeds around the planting site.
Dig a wide hole so the surrounding soil is loosened and roots can expand.
Step 3: Position the tree
Remove the tree from its container carefully.
Place the tree so the top of the root ball is approximately level with the surrounding soil.
Do not bury the trunk.
Step 4: Backfill
Return the native soil around the root ball.
UF/IFAS specifically cautions against filling the planting hole with large amounts of compost or topsoil rather than using the surrounding native soil.
Step 5: Water thoroughly
Water the entire root zone immediately after planting.
Step 6: Mulch
Apply organic mulch around the root zone.
Keep mulch away from direct contact with the trunk.
—
Growing Sugar Apple From Seed
Sugar apple is commonly propagated from seed.
One interesting characteristic of sugar apple is that seedlings from a particular selection can show relatively little variation compared with many other fruit trees.
This makes seed propagation more practical than it is for some other tropical fruit crops.
However, if you want a particular named selection, a grafted tree gives you more certainty about what you’re growing.
To grow from seed:
Use fresh seeds from a healthy, desirable fruit.
Clean the seeds thoroughly.
Plant them in a well-draining growing medium.
Keep the medium consistently moist but not saturated.
Provide warmth and bright light.
Once seedlings become established, gradually move them into stronger sunlight.
Remember that seed-grown trees still require several years to become productive.
—
Growing Sugar Apple From Grafted Trees
Improved sugar apple selections can be propagated vegetatively through methods such as veneer grafting, cleft grafting, or budding onto suitable rootstocks.
For a homeowner who wants a specific variety, a grafted tree can be an excellent choice.
The major advantage is that you’re starting with known genetic material rather than hoping a seedling reproduces the exact characteristics you want.
A grafted tree may also help you establish a productive tree more quickly.
When purchasing one, ask the nursery:
– What cultivar is it?
– Is it grafted?
– What rootstock was used?
– How old is the tree?
– Has the parent tree produced fruit?
– Where was the parent tree grown?
—
How Long Does a Sugar Apple Tree Take to Produce Fruit?
The timing varies according to propagation method, variety, climate, tree health, and growing conditions.
A young tree should first be allowed to establish a strong root system and framework.
UF/IFAS recommends removing fruit that sets during approximately the first year or so after planting so that the young tree can concentrate its energy on vigorous growth.
Once the tree is established, the focus can gradually shift toward flowering, fruit set, and fruit development.
Don’t judge a sugar apple tree solely by its earliest years.
Cold damage can also delay production considerably in Central Florida.
—
How Can You Encourage Earlier Sugar Apple Production?
The objective is not to force a young tree into heavy production.
Instead, concentrate on building a healthy tree.
Focus on:
Full sunlight
Good light supports vigorous growth and fruit production.
Adequate nutrition
Provide regular balanced fertilizer while the tree is establishing.
Consistent moisture
Avoid prolonged drought during active growth, flowering, and fruit development.
Good drainage
Sugar apple does not tolerate continuously wet or flooded soil.
Proper pruning
Maintain a manageable tree with good light penetration.
Cold protection
Avoid allowing young trees to suffer repeated freeze damage.
Patience
A strong tree is more valuable than a tree forced to carry fruit before it is ready.
—
Fertilizing Sugar Apple Trees
Sugar apples benefit from regular fertilization, especially while young.
UF/IFAS recommends frequent applications of complete fertilizer during the early years, with fertilizer rates increasing as trees become larger and more established. As trees begin producing fruit, the number of nitrogen-containing fertilizer applications is reduced.
Fertilizer programs should also account for Florida’s sandy soils and potential micronutrient deficiencies.
Important nutrients can include:
– Nitrogen
– Phosphorus
– Potassium
– Magnesium
– Zinc
– Manganese
– Iron
Young trees
Young trees benefit from smaller, more frequent applications during active growth.
Mature trees
As trees become productive, fertilizer management changes.
The goal is to support flowering and fruit production without encouraging excessive vegetative growth.
UF/IFAS also recommends attention to micronutrients such as magnesium, zinc, and manganese, with iron applications when appropriate for the soil conditions.
When diagnosing nutrient problems, soil testing can be useful.
—
Watering Sugar Apple Trees
Sugar apple can tolerate some drought, but drought stress can reduce growth, fruit set, fruit size, and overall crop production.
Water is especially important during:
– Active growth
– Flowering
– Fruit set
– Fruit development
However, there is an important balance.
Do not keep the root zone constantly wet.
UF/IFAS reports that sugar apple is not tolerant of excessively wet or flooded soils and that prolonged flooding can cause root problems and even tree death.
This is particularly important in Florida, where summer rainfall can be heavy.
If your property has poor drainage, improve the planting site rather than simply increasing irrigation.
—
Pruning Sugar Apple Trees
Pruning is one of the best ways to keep a sugar apple tree manageable.
An unpruned tree can reach around 20 feet, but UF/IFAS notes that periodic pruning can maintain sugar apple trees at approximately 8–12 feet.
A smaller tree has several advantages for a homeowner.
It is easier to:
– Harvest
– Protect from cold
– Inspect
– Monitor for pests
– Apply treatments when needed
– Keep fruit within reach
Young trees
Allow the tree to establish during its first season.
The following spring, begin developing a strong branching framework.
Select well-spaced branches and remove poorly positioned growth.
Mature trees
Annual selective pruning can maintain the canopy and improve light penetration.
UF/IFAS recommends removing approximately one-third of the previous year’s vegetative growth during early spring as the tree begins new growth.
Don’t simply cut the entire tree back indiscriminately.
The goal is a healthy, open, manageable canopy.
—
Sugar Apple Flowering
Sugar apple generally flowers during the warmer part of the year.
UF/IFAS reports flowering from approximately March through June in Florida, although timing can vary with weather and location.
The flowers have an unusual pollination pattern.
The female stage occurs before the flowers begin shedding pollen.
This creates an opportunity for poor natural fruit set under some conditions.
Temperature, humidity, wind, insect activity, and tree health can all influence flowering and fruit production.
—
Sugar Apple Pollination
Pollination is one of the most important subjects for sugar apple growers.
Sugar apple flowers are functionally female before they become pollen-shedding male flowers.
UF/IFAS describes the female stage as occurring earlier and the pollen-shedding stage later, which can limit natural self-pollination.
In areas with limited natural pollinator activity, hand pollination can improve fruit set.
Basic hand-pollination concept
Collect pollen from flowers in the pollen-shedding stage.
Transfer that pollen to receptive flowers.
A small artist’s brush can be useful for transferring pollen.
The goal is to move pollen from a mature male-stage flower to a receptive female-stage flower.
For growers interested in maximizing fruit production, learning hand pollination can be extremely worthwhile.
—
Sugar Apple Fruit Development
After successful pollination, the small fruit begins developing.
Monitor developing fruit regularly.
Watch for:
– Insect damage
– Misshapen fruit
– Premature fruit drop
– Fungal problems
– Branch stress
Good nutrition and adequate moisture are particularly important during fruit development.
Avoid allowing the tree to experience severe drought while fruit is developing.
—
Protecting Sugar Apple From Florida Cold
This is the section Central Florida growers need to take seriously.
Sugar apple is one of the more cold-sensitive fruits in our growing program.
UF/IFAS reports that unprotected young trees can be severely damaged or killed at approximately 30–32°F. Its broader Florida tropical-fruit guidance lists mature sugar apple freeze damage around 28–29°F, while also noting that chilling injury can occur with extended exposure to temperatures below approximately 50°F.
Before a freeze
For a young tree:
– Water appropriately if the soil is dry.
– Have frost cloth ready.
– Protect the trunk when practical.
– Cover the canopy when the tree is small enough.
– Move container trees to shelter.
– Take advantage of protected microclimates.
Do not rely on plastic touching the foliage.
Choosing the location
A warm location can make an enormous difference.
Consider planting near:
– A south-facing wall
– A house
– A protected courtyard
– A windbreak
– Other structures that retain heat
Avoid exposed low spots.
After a freeze
Don’t immediately cut off every damaged branch.
Cold injury may not become obvious immediately.
Wait until you can determine which tissue has survived before performing major corrective pruning.
—
Common Sugar Apple Problems
Several problems are especially important for Florida growers.
Poor drainage
Continuously wet soil can cause serious root problems.
Cold damage
Freezing temperatures can severely damage young trees.
Poor fruit set
Inadequate pollination can result in few fruits.
Drought stress
Extended drought can reduce fruit set, fruit size, and yield.
Excessive shade
Too little sunlight can reduce growth and fruit production.
—
Sugar Apple Pests
Sugar apple can be affected by several insect pests.
One particularly important Florida pest is the annona seed borer.
UF/IFAS identifies the annona seed borer as the most important insect pest of sugar apple in Florida.
Other insects can also affect:
– Leaves
– New shoots
– Flowers
– Developing fruit
Inspect trees regularly.
Look for:
– Holes
– Damaged fruit
– Insect activity
– Discolored leaves
– Scale
– Caterpillars
– Webbing
– Premature fruit drop
Good sanitation and regular inspection can help you identify problems before they become severe.
—
Sugar Apple Diseases
Sugar apple can experience disease problems, particularly when conditions are warm and wet.
Good cultural practices are an important first line of defense.
Reduce disease pressure by:
– Providing good drainage
– Avoiding unnecessary irrigation
– Maintaining an open canopy
– Removing severely damaged plant material
– Keeping fallen fruit and debris under control
– Monitoring developing fruit
Don’t automatically treat a problem without identifying it first.
If you’re unsure what you’re seeing, take clear photographs and seek a reliable diagnosis before applying a pesticide or fungicide.
—
Growing Sugar Apple in Containers
A young sugar apple can be grown in a container, and container growing has one major advantage in Central Florida:
You can move the tree when serious cold threatens.
This can be useful for young plants.
Choose:
– A large, deep container
– Excellent drainage
– Quality growing medium
– A sunny location
– A practical way to move the tree
However, container-grown sugar apples require more attention to watering and root development.
A mature tree eventually needs substantial root space.
If you intend to keep a sugar apple permanently in a container, regular root and canopy management becomes important.
—
When Are Sugar Apples Ready to Harvest?
Harvest timing is one of the most important skills to learn with sugar apple.
The fruit should generally be harvested when it has reached physiological maturity but before it becomes excessively soft on the tree.
Look for changes in:
– Segment separation
– Skin color
– Fruit softness
– Aroma
– Overall appearance
The exact signs vary among cultivars.
Learn the characteristics of your specific tree.
A sugar apple that is picked too early may fail to develop its best flavor.
One that is left too long can become damaged, split, or difficult to handle.
—
How to Harvest Sugar Apples
Handle sugar apples gently.
The fruit is relatively delicate and can bruise easily.
Use clean pruning shears when necessary and avoid dropping fruit.
Harvesting over several days or weeks may be preferable to allowing every fruit to become fully ripe simultaneously.
This is especially important if you have several trees.
A steady harvest is easier to eat, preserve, share, or sell.
—
How Much Fruit Can a Sugar Apple Tree Produce?
Production varies considerably from tree to tree.
UF/IFAS reports yields of approximately 20–50 fruit, or about 10–50 pounds, per tree, depending on climate, pollination, disease and insect pressure, and cultural practices.
A separate UF/IFAS economic publication uses approximately 25 pounds per mature tree as an industry production assumption for its South Florida economic model.
These figures should not be treated as guarantees for a backyard tree in Central Florida.
Your actual crop may be lower or higher.
Record your own results.
Track:
– Variety
– Tree age
– Number of fruit
– Total weight
– Average fruit weight
– Harvest dates
– Fruit quality
– Pest losses
– Fruit sold
– Fruit consumed at home
Those numbers become much more valuable to you than a generic yield estimate.
—
Is Growing Sugar Apples Profitable?
Sugar apple can be an interesting specialty fruit, but profitability is highly dependent on where and how you sell it.
The fruit is delicate and has a relatively short postharvest life, which makes local direct sales more practical than shipping it long distances.
UF/IFAS notes that Florida commercial sugar apple production is concentrated in warm areas of South Florida, particularly Miami-Dade County.
That doesn’t mean a Central Florida homeowner cannot sell sugar apples.
It means you should think of the crop as a local specialty product rather than a commodity crop.
Potential income sources include:
– Fresh fruit
– Premium varieties
– Direct-to-consumer sales
– Farmers markets
– Farm-gate sales where permitted
– Local specialty customers
– Plants
– Grafted trees
– Propagation material where permitted
For the actual numbers, see our dedicated Sugar Apple Profitability guide.
There we can examine potential yield, selling price, growing costs, and realistic backyard revenue.

Selling Homegrown Sugar Apples
Sugar apple can be an appealing fruit for customers who already know and love tropical fruit.
You may find customers interested in:
– Fresh ripe sugar apples
– Pink or red sugar apples
– Thai Lessard
– Unusual local fruit
– Freshly harvested tropical fruit
– Sugar apple plants
Because the fruit is delicate, local customers are particularly important.
Instead of trying to compete with large commercial fruit distributors, a small grower can potentially focus on freshness and variety.
When selling fruit, explain how to tell when it is ripe.
Many people who have never eaten sugar apple won’t know what to look for.
Before selling fruit or plants, check current Florida and local rules that apply to your specific type of sale.
