The soursop tree, also known as Graviola or Guanábana, is a tropical wonder. Also called soursop, it has been traditionally used to treat ailments and is believed to offer potential health benefits for conditions such as cancer, diabetes, and inflammation. Famous for its spiky green fruit and sweet, tangy pulp, this tree is beloved not only for its unique flavor but also for its health benefits. But for many home growers, getting a soursop tree to bear fruit and knowing when that fruit is ripe can feel like a mystery.
Whether you’re growing one in your backyard or keeping it potted on your patio, this guide will walk you through the exact steps to get your soursop tree to fruit, recognize when it’s ready to harvest, and explore the best ways to enjoy and preserve it.
Why Isn’t My Soursop Tree Producing Fruit?
There are several reasons your tree may be falling short in the fruit department. These include:
- Lack of pollination
- Poor soil conditions
- Inadequate sunlight
- Improper watering
- Tree immaturity
Let’s break these down and offer solutions.
Step 1: Boosting Pollination
Why Pollination Matters
In nature, soursop trees rely on beetles for pollination. Unfortunately, in many backyards, these natural pollinators are nowhere to be found.
Hand Pollination: Your Best Bet
If your tree isn’t fruiting, try hand-pollinating. Here’s how:
- Use a small brush or cotton swab.
- In the early morning, collect pollen from a male flower, you’ll see visible yellow grains.
- Transfer it to a female flower, which opens later and has a central ovary.
- Repeat this during the blooming season.
How Can You Tell if a Soursop Flower is Male or Female?
Male flowers usually open first and release pollen. Female flowers follow and are ready to receive pollen. You’ll want to catch this timing carefully to increase your chances of success.
Step 2: Soil and Location
What Type of Soil Does Soursop Need?
Soursop trees thrive in rich, well-draining soil.
- Ideal pH: 6.0–6.5
- Avoid clay-heavy, waterlogged ground.
- Add compost and organic matter to enrich the soil.
Step 3: Give It Plenty of Sun
How Much Sunlight Does a Soursop Tree Need?
Soursop trees love full sun. Make sure yours gets at least 6–8 hours of direct sunlight daily. Avoid placing it near taller trees or walls that cast shadows.
Step 4: Master the Watering Routine
Watering Basics
- Deep water 2–3 times per week, depending on climate.
- Let the top 2 inches of soil dry out between watering.
Signs You’re Doing It Wrong
- Yellow leaves: Overwatering
- Crispy or curled leaves: Underwatering
Step 5: Fertilize Smartly
What Is the Best Fertilizer for Soursop Trees?
Look for an organic fertilizer high in phosphorus and potassium. These support blooming and fruit development.
Fertilizing Schedule
Feed your soursop tree every 6–8 weeks during the growing season. Avoid fertilizers that are high in nitrogen, too much nitrogen encourages leafy growth, not fruit.
Step 6: Regular Pruning
Why You Should Prune
Pruning helps the tree breathe, prevents disease, and directs energy to fruiting branches.
How and When to Prune
Once a year:
- Remove dead or damaged branches
- Eliminate suckers from the base
- Thin out crowded areas
5. Prune Regularly
Pruning improves air circulation and helps the tree focus its energy on fruit production.
-Tips:
- Prune dead or crowded branches annually.
- Remove suckers from the base of the tree.
Step 7: Consider the Tree’s Age
How Long Does It Take for a Soursop Tree to Bear Fruit?
From seed, a soursop tree takes 3–5 years to bear fruit. Grafted trees may start fruiting in as little as 2 years.
If your tree is still young, be patient, it might not be ready yet.
Step 8: Watch the Weather
Protect from Wind and Cold
Strong wind can knock off flowers, and chilly nights can stunt growth. If needed, plant near a windbreak or wrap the trunk in winter.
How to Know When Soursop Is Ripe
Visual Clues
- Skin color changes from dark green to light green
- Spikes soften and flatten

Texture Test

How Long After Pollination?
Soursop typically ripens 4–5 months after flowering. Mark the bloom date for better tracking.
Harvesting Tips
Don’t Wait Too Long
If left on the tree too long, soursop can overripen and fall.
Harvesting Trick
Use garden shears and cut with some stem intact. Avoid pulling, it’s a delicate fruit.
