Custard Apple

Custard Apple

The custard apple is a large sub tropical deciduous tree reaching 10m in height and has a large spreading canopy that is shaded with large, green drooping leaves. The tree displays yellow trumpet shaped flowers that emit a pleasant sweet smell, with only a small number of flowers setting fruit. The fruits are variable in shape with the outer being covered in rounded knobs, with the inside containing a custard like flesh.

  • Plant & Growing Tips:

    Prefers low elevations, warm sun and humid coastal climates with good summer rainfall.

    Custard apples tend to prefer sandy loam soils, but will still do fine in well structured clay loams.

    Plants require at least 1m of well drained soil to ensure good tree performance. Trees may need to be planted in mounds if the topsoil is less than 1m deep.

    Wind sensitive and does not take well to frosts especially young plants.

    Ideally, humidity around 70 – 80% is best for fruit growth and development. Dry inland areas do not provide enough humidity for fruit set and should be avoided.

    Irrigate young trees every 15-20 days for first few years except during winter. With bearing trees, discontinue watering as soon as fruits are fully grown.

    When young, start to structure trees by pruning to an open vase shape and maintain until tree matures. Keep canopy open to allow for light penetration and to achieve greater fruit distribution throughout the canopy.

    When planting your custard apple, plant them at a wide spacing: 6 – 7.5m apart and 8m between rows for the African Pride variety. Pink Mammoths, KJ Pinks and Maroochy Gold require slightly larger growing space: 9-10m apart and 10m between rows.

    Plant custard apple trees during late winter.

  • Fertiliser Applications:

    Stage: Pre-Plant

    Product: Dinofert Organic Fertiliser, Dinofert Standard Pellets

    Gardener Use: 4kg/site

    Commercial Use: 4kg

    Comments: Apply 2-3 months prior to planting to an area 1.5m across the site and incorporate to about 15cm deep.

     

    Stage: Young Trees 

    Product: Dinofert Organic Fertiliser, Dinofert Standard Pellets

    Gardener Use: 4 cups (800g)

    Commercial Use: 700-900g

    Comments: Apply after 6 months starting at 200g per tree increasing by a further 200g by the next application (400g) which is another 6 months later. Keep increasing the rates by 200g until a total of 800g is reached (this should be by the end of the 2nd year). Maintain this amount until the tree is bearing fruit. The fertiliser can be applied in trenches 15cm deep and 20cm wide around each tree at a distance of 1-1.5m from the base of the tree. As the tree matures, the trench will need to be extended to an appropriate greater distance.

     

    Stage: Mature Trees

    Product: Dinofert Organic Fertiliser, Dinofert Standard Pellets

    Gardener Use: 4-8 cups (0.8-1.6kg)

    Commercial Use: 1-1.6kg

    Comments: Apply in early autumn, early spring and in mid-summer. When using Dinofert fertilisers, allowances must be made for crop load. Increase rates for heavy bearing trees up to 1.6kg per tree for each application (total of 4.8kg fertiliser per year).

Please note that the above information and recommendations are provided in good faith and are given without liability for loss or damage suffered as a result of their application. Optimum response to fertilisers will only be achieved when weeds, insect pests and diseases are controlled and adequate soil water is available.

Fertiliser use recommendations are presented as a practical guide to good agronomic practice under most situations. Local soil, climatic and other conditions should also be taken into account as these could affect plant response to fertiliser rates and applications.

For further information we recommend you seek advice from your local agronomist.
