Native to Brazil, the cashew is grown throughout tropical regions around the world. The cashew is an attractive small evergreen tree with a dense, symmetrical, spreading canopy, displaying rose coloured, scented flowers in panicles followed by an edible fruit known as the cashew apple. The cashew apple has been consumed for centuries by Aztec tribes, although this is not the most valued item of the plant. The most important component of the cashew is at the bottom of the cashew apple which is encased in the kidney shaped shell.

  • Plant & Growing Tips:

    The cashew is hardy and can cope with poor soils. However, cashews do best in deep, well drained, sandy or sandy loam soils. They should not be grown on heavy clay soils.

    Cashews are resistant to drought and will continue to thrive in dry seasons in excess of 40°C.

    Provide a location that is frost free, receives plenty of sunlight and is protected from strong winds.

    Newly planted cashews should be watered at planting and on a daily basis for the first week and then only once or twice a week for young cashews (first 3 years).

    Mulch can be used around the base of young cashews to help retain moisture.

    Mature cashews are rather resilient and can still produce quite well without irrigation, but for optimal yields weekly irrigation is necessary. During winter, little or no irrigation is generally needed.

    When sowing seeds, plant 2 inches deep, use 3-4 seeds and expect germination after 2-4 weeks. Keep only the healthiest seedling.

    Spacing when planting needs to be 4.5 - 6m between cashew trees.

    For the first 2 years formative pruning may be desirable to encourage lateral branching and growth. During spring and summer, remove 1-2 inches from all shoot tips which will stimulate new growth and promote the development of a more compact, well structured tree.

    For commercial growers, machinery is essential for maintenance, so steep slopes or rocky soils should be avoided.

  • Fertiliser Applications:

    Product: Dinofert Organic Fertiliser, Dinofert Standard Pellets

    Gardener Use: 7-12 cups (1.4-2.4kg)

    Commercial Use: Up to 3kg

    Comments: Promote growth of plants and advance onset of flowering and fruit, apply in late August and then every 30-60 days up until March.


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.
