Growing Custard Apple in Australia: The Complete Guide
Custard Apple is a moderate subtropical fruit tree to grow, needing full , sheltered sun with regular watering.
We get asked about custard apple often enough that it's worth setting out the full picture here, beyond what fits on our printable card.
Often needs hand pollination
Custard apple flowers have a biology that makes natural pollination unreliable in home gardens — many growers hand-pollinate with a small brush to get a good fruit set.
Planting Custard Apple
Method — plant with the root flare at soil level; stake young trees. Soil — well-drained, moderately fertile. Timing — plant in spring, warm frost-free zones.
Ongoing Care
Keep these points in mind:
- Hand-pollinate flowers with a small brush for reliable fruit set.
- Water regularly through the growing season.
- Feed lightly after harvest.
- Protect from frost while young.
Common Problems
Worth paying attention to:
- Poor fruit set — natural pollination is often unreliable; hand-pollinate.
- Fruit fly — net or bag developing fruit.
- Mealybug — check developing fruit and treat with horticultural oil.
- Frost damage — vulnerable while young.
When and How to Harvest
Signs — skin segments soften slightly and colour lightens between them. Method — cut with a short stem attached, handle gently — fruit bruises easily. Curing — ripen at room temperature for a few days. Storage — ripe fruit in the fridge, a couple of days.
