How to Grow Star Apple from Seed

  1. Remove seeds:

    Cut a ripe fruit in half and remove the seeds. Be aware most seeds do not grow true to type.

  2. Clean Seeds:

    Rinse seeds then leave them in a bowl for 24 hours. Seeds lose viability fairly quickly. You should sow them within a month of collection.

  3. Prepare:

    Fill a starting pot with potting mix and then water thoroughly.

  4. Sow:

    Place the seeds on the surface of the potting mix. Spread a thin layer of potting mix over the seeds. Then lightly tap it down.

  5. Germination:

    Leave the pot in a sunny location and water at least weekly. Do not overdo it, as your seed will rot if your medium is permanently soggy. You should see a sprout after 25 – 30 days.

  6. Transplant:

    After a month or two transplant your seedling into a new pot or to your preferred location in the garden.

We fertilise at the start of the ‘wet season’ and two more times before the end of the wet. That is just 3 times per year, two months apart.


Make sure you water your tree every week for the first two months after planting. After this you will need to water only every few weeks during the dry season (a nice deep watering). During a typical wet season no watering is necessary.

Mulching around your trees will reduce evaporation and help you save a little on water. Plus your tree will love it.
