How to grow radish

Regularly sow radish seed 0.5cm deep in rows 10-15cm apart. Thin seedlings of summer varieties to 2.5cm winter varieties (sown from July) to 10cm.

Remove weeds around your radish seedlings by hand to avoid disturbing the roots. Water weekly in dry weather for rapid and continuous growth.

Protect with a cloche if the weather is particularly cold in February and March.

Harvesting and using radish

Pull up summer varieties when they're small (from the size of a 5p coin) as bigger roots will become woody. Pull up larger winter varieties from autumn as needed.

Tips on growing radish
