Time needed: 3 minutes

How to grow a Custard Apple Tree from Seed.

  1. Collect seeds.

    Scoop out the seeds from a ripe custard apple fruit. Rinse seeds to remove some of the pulp.

  2. Soak and dry seeds.

    Soak the seeds in water for a day or two. Throw out those that float and remove the others and place them on newspaper or a paper towel to dry out. After drying for a week they are ready for planting.

  3. Plant seeds.

    Plant seeds 2 or 3 cm (1 inch) deep in a container of potting mix. Water and then leave in direct sunlight.

  4. Germination.

    The seeds will germinate in 3 weeks or so. When your plant becomes too big for the container, plant it out into the place it will live out its life.

  5. Patience.

    Trees grown from seed should crop in 4 to 6 years.

Location and Soil

The custard apple tree thrives in the tropics as an evergreen perennial. It can be grown in the sub-tropics as well, but in colder regions it will become deciduous.

When growing, go for well-draining soil that is sandy and loamy. A mixture of sand and garden soil is best. This plant is forgiving of poor soil, but areas that become waterlogged should be avoided.

Fertilising

Apply a citrus fertiliser every three months until the tree begins to bear fruit. Feeding potash is done to increase flowering.

Regular fertilising of mature trees is not common, but when done it is known to increase longevity and slow the decline of trees.

Pruning

Pruning your custard apple tree serves a number of purposes. It can help to restore the centre of gravity to a tree that is leaning (you can also stake young trees to help with this).

Pruning can also keep your tree a manageable size for an urban environment and make fruit production more prolific. It can also make it easier for you to harvest the fruit, by keeping them at a height you can reach.

Growing in a pot

Start off in a 35 litre (10 gallon) container and upgrade to a 90 litre (24 gallon) container when growth requires repotting. Also remember to make sure the top of the root ball is level with the top of the pot.

Make sure your container drains well and place it in a sunny spot.

Watering

Water trees regularly throughout the dry season. However, during the ‘wet’ they will be fine without any additional water.
