I have been trying to grow radishes for over 2 months now and I haven't had a single good crop. Either no round radish root at all or a very small pathetic root. What am I doing wrong??

Hi, I know its too late now..but when your tomato season begins, purchase a punnet of your favourite tommies.. then when the laterals are about pencil thickness,,intead of pinching them off.. buy a carton of beer (cans) when empty, cut the bottoms off, fill with garden soil, and stick the laterals in..water keep moist and you will get 20/30 tomato plants from one punnet..:) not only do you get loads of your favourite tommies,,!! you also enjoy emptying the cans...

I cannot grow radishes. They always end up all tops and nothing underneath. What am I doing wrong as they say any idiot can grown radishes.

As a commercial grower of radish (primex), I always remember the advice given to me many years ago, that being to never fertilise radish. As radish is one of the fastest growing vegetables, too much fertiliser causes the leaves to outgrow the root. Long leaves have no shelf life, just look in your local supermarket. I actually apply a VERY light application of Nitrophoska Blue which gives the leaves a beautiful velvety texture. I pick the radish when they are the size of a ten cent piece and leaves about four inches long. One of the great pleasures of my life is washing the bunches of radish and packing them in boxes of thirty for sale knowing that some-one is going to enjoy eating them as much as I enjoy growing them.

my radish leaves are turning yellow - what could be the reason?

Interesting what Robert said. I even spoke to yates and they told me to go easy on the liquid fertiliser/Nitrogen and appy a sprinkle of Superphosphate between the rows but this has made no difference whatsoever. Are we justing getting crap seed growing stock these day?.............because I grew radish as a kid and never had these problems as I would just dig up the ground and stick seeds in and they would grow just fine. What about sunlight? Surely other people here with same problem can't have their garden in a spot that doesn't get enough sun!?

Have you tried checking the composition of your soil?

Maybe a tip from the Bavarians: slice the radish thinly and sprinkle with salt. This will neutralise the bitter taste, and the salt will wash out with the liquid. You will need about a tea spoon of salt per 300mm (=foot) of radish. The connoisseur will do ONE spiral cut along the whole length of the radish with about 1mm pitch.

How long does it take for radishes to seed?
