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

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.

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.

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 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??

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.

how long will it take for the radish seeds to be visible??
