Small, spicy tasting root vegetable usually round but some longer varieties . Available in a range of colours between red and white.

Very easy to grow. Good for a child's first garden as seedlings appear in two or three days. Sow between other vegetables as they will mark the rows until the slower germinating plants appear.

Culinary hints - cooking and eating Radish

Wash well and remove leaves and roots.
Use raw in salads or on their own with bread and butter.

Long Scarlet radishes are good in a stirfry. All radishes make a great pickle.

Could I please know why my radishes are so bitter? Last year tasted nice!

Rex, I've found lack of water at any stage during growth will make radish turn bitter. It's also a dreadful problem with cucumbers - one day of wilting makes them completely inedible!

Can you eat the leaves of radish e.g. in salad or cooked
11 Jun 08, Chris (Unknown climate)
Christine, you can probably eat them without harm (they're a brassica), but the leaves are usually covered in prickly hairs, so why you'd want to is the main question - I would rather just eat the radish. You can certainly eat turnip and beetroot leaves, so radish leaves might be ok cooked? Perhaps you can let us know how you go with them?

how long will it take for the radish seeds to be visible??

Make sure radishes have enough water and don't let them become too enormous. If they are water deprived or get too big, they can become bitter. From sowing to harvesting, they are one of the quickest growers (if happy...6-8 weeks). They also love a dose of potash.

Does anyone know why some of my radishes are splitting? Only some came out perfect.

The most likely reason is that you have left them in the ground too long.

Your pot size must be relative to the size of the radish. Radishes come in sizes ranging from 2cm to 30cm & larger !
