  • Space plants: 1 - 2 inches apart
  • Harvest in 5-7 weeks.
  • Compatible with (can grow beside): Chervil, cress,lettuce, leeks, spinach, strawberries, tomatoes
  • Avoid growing close to: Hyssop, gherkins
  • Cherry radish
  • French Breakfast radishes

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.

I always grow radish but often let them get too fibrey. I let some go to seed, amd found my sugarbag bees loved them. I then let them go to seed and found the young, tender seed pods are tastier than the radish itself, and you get far more output as they seed like crazy. Pickling the pods also works well, so now I grow them for the seed pods, and the bees. I recommend trying it

Pick your radish when they have grown to the right size and put them down in the veggie section of fridge - they will keep for weeks. They are more a late autumn winter early spring crop in sub tropics.

What kind of radishes are you growing?

I'm growing radishes for the first time.Tasty! What does 'they will mark the rows' mean? Thanx.

Radish will mark the row next door if planted next to some other seeds that come up in more days than radishes. For example if you plant __?__ veggie that comes up in 10 days, next to a row of radishes, the radishes will come up certainly by day 2 ( all things present as to sunlight and water). That mean the ?? veggie will be along side and in next row but not until day 10. That way you know not to plant something else in row space next to radishes. Neat trick I never thought of. Wish I had marked my lettuce groups with one radish seed in middle.

They are talking about planting radish with other seeds to mark the row. Like a couple of radish between two lettuce seeds/plants. Radish will germinate in 2-5 days to show where the others are planted. I suggest you do a thin line of radish.by itself. Plant the other seeds in a different row. What I do now is have soil nice and fine and level, pat it down a bit., then plant seeds in a thin row - pinch a few seeds in your fingers and wriggle your fingers to release a seed or two at a time. Then cover the seeds with seed raising mix or fine potting mix. Try and keep the seeds shaded until they germinate. Keep the plant area moist all the time.

This is great advice for a beginner. Thanks.

My baby sprouts were devoured in my raised bed, despite using bird netting. No bugs visible. What could it be??? So bummed.

You may have to go out at night to see what eats them. Could be snails or worms etc. If you can buy it, try some veggie netting.

Someone is eating my radish leaves. Tiny pinprick holes. Any advice?

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.
