Composting Contaminated Carrots
Every year my carrots have carrot root fly.
The ones I'm digging at the moment have to have about 30% cut out and thrown away. I have been composting the waste - and suddenly wondered if that is OK. Would that perpetuate the problem? -- Chris |

Or try making a wooden compost filled open framework at least 18" above ground as per the Big Dig allotment programme last year. Apparently the blighters don't fly that high. I'll let you know later! |

Apparently the blighters don't fly that high. I'll let you know later! They're not strong flyers and an open windswept area is good. Also plant a row of onions for one row of carrots. I use rosemary near by and mulch the carrots so that beneficial crawlies can hide under and eat the psila if invaded. |

Excellent - thanks for your reassurance. This year I might grow them under fleece. Bit of a clat though ... no weeding etc. -- Chris |

Planting onions next to your carrots is great to deter the psila flies, off course. I'm sure you knew that but I didn't write it, didn't I. That's why I use rosemary myself, smells nicer too. |

Is it different from the ordinary white fleece from the garden centre? And how would you do weeding? If you removed the fleece to do weeding, wouldn't that let the root fly in? -- Chris |

Seems to stop the little blighters and you can step over it to weed etc. Last year I had no damage to my carrots or parsnip. Now if it was only so easy to stop the slugs.... George |

I have looked at them, but decided they were too expensive for the area they would be needed for, and I believe you have to repeat the treatment after a short while. Alan |

Having a perpetually wrecked crop so that you have to buy your veg in, or using nematodes (which also protect other crops) once or twice a year? I ask the question in a genuine spirit because I haven't costed them on your basis. We use them here, along with other bio controls and they work. I'm not saying we don't get ANY slugs but I am saying we get fewer slugs over 6 acres of garden and nursery combined. -- Sacha http://www.hillhousenursery.co.uk South Devon http://www.discoverdartmoor.co.uk/ (remove weeds from address) |

Although the nematodes kill slugs, unfortunately, the snail population then has free range to munch away without any competition:-( |

No, I suspect that the carrots are much tastier. -- regards andyw |
