The Radish is an edible root vegetable that comes in numerous varieties, varying in size, colour and duration of required cultivation time.  In Australia, we are more familiar with the small, crunchy pink or scarlet coloured roots that have become a standard ingredient in so many summer salads.
Radishes are categorized as either summer or winter crops. Summer radishes mature rapidly, with many varieties germinating in 3–7 days, and reaching maturity in three to four weeks. Winter radishes take longer and can be stored after harvesting.

  • Plant & Growing Tips:

    Radishes grow best in full sun location.

    In summer, they are happy in partial shade and have no objection to being planted amongst or near other crops.

    Radishes prefer light, sandy loams. Most soil types will work, though sandy loams are particularly good for winter and spring crops, while soils that form a hard crust can impair growth.

    As with other root crops, tilling the soil helps root growth and development. However, radishes are used in no-till farming to help reverse compaction.

    The secret to growing good radishes is to provide ample moisture.

    Radishes are a good starter crop for gardens and because they mature in 3 to 4 weeks.

    Thrives in cooler weather but dislikes frosts. It is best to plant out after the last frost date.

    Sow seeds of summer radish directly into the ground from early spring onwards, as soon as the soil has warmed up. Winter radishes can be sown in mid to late summer, but not too early or they will bolt.

    The depth at which seeds are planted affects the size of the root, from 1cm deep recommended for small radishes to 4cm for large radishes.

    Space your radishes 5cm apart within the row and 20 – 25cm apart between rows.

    Harvesting periods can be extended through repeated plantings, spaced a week or two apart.

  • Fertiliser Applications:

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.
