Hiya Martin, Had the same problem with lettuce and broccoli -- found the culprit/s were garden birds, swallows and wrens (obviously love the fresh new growth). I covered my new plants with 1.25l drink bottles with the neck cut off -- also acts as a mini hothouse. Have you considered slugs and snails? Good Luck.

Hello, My name is Carol. I am the wife of a farmer, J.Thompson, we grow all different types of fruits and veg, we grow a lot of carrots, tomatoes, snow peas and radish. All those rules and tips are nothing like the real deal. Basically depending on the type of radish, you use sufficent fertilizer, you dig a hole, place your seeds about 3-5cm apart (they need room to grow!) and give them 600mLs of water everyday. After about 2 weeks you should be finding some results. If nothing has changed and there is still no signs of radish, it is a dodgy brand of seeds, you are not giving it enough sunlight, it is just a dodgy seed or you need to take better care of it. THAT is the real deal. Do not believe any of that scientific stuff! it is just nature. Thankyou I hope your radish grow successfully.

my radishes seem to grow with the roots above the surface. The ground is a clay but I have it quite loose with some organic matter. would it be best to leave them as they are or to build the soil up around the base of each plant?

I would like to know that if after my radishes have come through and have been picked, will they keep growing or do i need to re sow more every time.

You will need to resow, preferably in a different place to avoid pests building up in the one location.

I planted radishes a few weeks ago and the seeds started to break through pretty much immediately. They have now refused to come out properly. I can see a little bit of withered leaves almost in the ground. What am I doing wrong?

As a good story about radish.... I live in south-west Brisbane... planted in early August and thinned out 3 weeks later... they were ready in another 3 weeks. Originally put blood and bone in well turned soil, kept them well watered. I still found some of them split though but not sure why but the rest were huge. Pity I don't eat them, gave most away and the rest went on the compost heap.

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?
