  • 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

  • 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.

why are my radish going to seed? Have very big top and no radish.. have done for about 3 years .

If they have very big leafy tops you are over fertilising BIG TIME. Plant radish after a leafy crop so that a lot of the N has been used. My experience is to grow radish into winter -sub tropical.

My radishes came out too small or not developed a full bulb/root at all. I used a peat based potting soil and compost + vermiculite also amended with fish/kelp emulsion. I am growing them in 6 inch deep flats with proper drainage holes. The variety is Cherry Belles, Rover, French Breakfast. Planted them in late summer for fall.

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.

Most of the heat is in the outer - red - skin. As a small child I'd peel that away (thumbnail worked well) and eat the white flesh inside, which is much milder. The leftover skin can be used in cooking, where they lose the peppery taste. Another way to use overly hot radishes is therefore to cut them into halves or quarters, coat in oil, and roast them in a hot oven (say 220C) until coloured and not too watery inside (30 mins or more).
