  • 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

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.

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

Hi!! Would anyone be able to give some advice as to why my radishes when I picked them today, found that the base of them were split and not very healthy looking, rough skin? Could there be an issue in the soil? Thanks in advance.

A bit of a contradiction - splitting maybe too wet and tough could be too dry. I find I grow the best radishes in the winter - a light watering each day.

I picked some today - rough looking, probably a bit tough. They are longer than the winter ones - the root seems to be growing longer in search of water even though I water them every day or two. The winter ones are a lot better looking.

I grow radishes a few years ago and they were so hot and spicy and I wanted to have another go, but when I went to the shop they had three or four different type. I just want to know which ones are mild and I can grow here in Brisbane.

I have grown them for 40+ years and I think it has to do with watering and weather. Better grown into/in the winter - a more even growing conditions - smaller variation of temp and water in the soil. If grown in the hotter weather they can dry out a bit and I think this makes them hotter. Try and grow quickly. Pick as soon as they reach the required size. They will keep in the fridge for weeks.

You mentioned that Radishes are best planted at three times the seed's diameter. Could you suggest a specific depth for a variety such as a Cherry Radish?

I received some cherry radish in the mail yesterday and it says 10mm deep.

Just run the rake handle in the soil to make a small furrow 4-6mm deep. Shake a few seeds into one hand and then pick up a few with the other hand and drop along the furrow. When finished cover the seeds with 4-6mm of soil. Water them morning and night. You could put a piece of shade cloth over the top of them until they germinate.

Can I grow Radishes in pots . Deep pots. I live in Capel , Western Australia.

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