How to Grow Radishes at Home

Some like it hot and some like it peppery and what makes the mighty radish so wonderful is that it combines both of these flavours and ensures every salad bowl bursts with colour and depth of flavour. It is one of the easiest vegetables to grow, maturing quickly and offering taste buds a range of flavours and textures when cooked or raw.

The trick to growing radishes is to harvest them when they’re small, unless you really do like it hot. The larger the crop the stronger the taste will be. You’ll also find that there are winter varieties as well. These tend to be black in colour and offer a stronger flavour than that of the red radishes we often come by.

Through July and August you can grow your radishes ready to be harvested in the late summer. They need to be sown directly into the ground where little shade is provided. These crops are incredibly easy to grow and below you’ll discover how you can grow yours at home:


1.    Sow seeds approximately 2.5cm apart in rows that are 15cm apart. However, winter varieties are given a bit more space, about 15cm apart per seed
2.    Radishes are prone to flea beetles, so if your crops look as if they’ve been attacked, sprinkle powdered dry soil over them
3.    Water the crop well during mid-summer
4.    When they are roughly the size of a 10p piece, begin to harvest your radish crop


Radishes should be kept refrigerated with many varieties able to keep for up to two weeks. However, if you are growing black radishes you’ll be pleased to know that they can be stored for months at a time.
