To avoid worms in your radishes, put wood ashes in the rows just before planting them. I have used that method and it works.

I want to try something different with another of section of radishes I want to plant here in the next day or two.

My radishes bolted but they also didnt form a sizeable bulb or if they did, they had kind of like a worm section eaten out.

So I am going to go down to the greenhouse or home depot or something and ask what is available to avoid this problem. I was reading on some blogs and one lady used sluggo and says that it worked great. I dont think this was slugs though. Another person said to use some stuff you mix into the soil that has tiny jagged egdes and it kills the worms. Another person said that doesnt work very well. Maybe they didnt use enough. Another person said to use a floating row cover. I dont want to get one of those. Another website mentioned planting mint close by because bugs dont like mint. I might try that. I will go talk to some people first before I decide and plant this section of radishes though.
