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.

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.

A better suggestion is a Styrofoam box used for corn or zucchini - if you can find bigger boxes the better - you can grow more at a time. Go to Foodworks, IGA or any supermarket and ask if they have any. Put newspaper, shade cloth or bubble wrap on the bottom - then about 25 mm of small pebble (the beach) - then another layer of paper, shade cloth or bubble wrap with some holes in it. Mix up some soil, sand, compost/manure and potting mix/seed raising mix. Put that in the box and give a good watering. Plant the radish and sprinkle some soil/ potting mix/seed raising mix over the radish. Keep out of the sun until they germinate or put some shade cloth or something similar over them until they germinate. With this free draining soil and shallow soil depth they will need watering each day and plenty of sun. Have 2-3-4 boxes and have a succession of plantings. This method can be also used to grow lettuce and baby spinach - plant very densely and cut the young leaves about 25-50 mm up the plant and they will reshoot - multiply cuttings. You can buy seeds on the internet 100-200 seeds for $1.
