Radishes are not winter-hardy.
Tip:
You can sow radishes in heated greenhouses so that you can harvest them through the whole winter.

Water regularly but only fertilise a little.
If you water and fertilise too little, then the root will grow slowly, will be dry and woody.
Tips:

• Radishes can be sown between the well-spaced rows of other vegetables which are good companions.
• It's possible to grow them in batches at intervals of time.

Pests: Cabbage white butterfly caterpillars, flea beetles
Preventative measures:

• Always keep the soil moist and hoe regularly to keep flea beetles away.
• A cardboard collar around the root crown can prevent the cabbage root flies or cabbage white butterflies from laying eggs.

If you wait too long with the harvest, they can become woody.

Remove the leaves because they take moisture and nutrients from the root.
Radishes can be wrapped in moist kitchen paper, and kept in a cool place (e.g. overnight on the terrace) for several days.

Radish leaves can be prepared like spinach leaves.
