  • carrot fly barrier help

    good morning,can anyone help me.I read somewhere that a screen of polythene will help prevent the dreaded carrot fly,is this true,what i mean is a two foot high polythene barrier round my bed.
    Also am planting carrots and onions together, any advice on this as well

    I wouldn't use polythene: it'll get really hot & sweaty in the sunshine. Also, the wind will rip it and the carrot fly can get blown over things into any enclosure.

    In my experience, intercropping with onions doesn't work either: the only thing that does is to keep the crop covered with fine mesh or fleece

        I'm with TS... barrier might work on a row by row basis but a wider enclosure doesn't...neither do aliums

        You can grow em flatish under fleece(not suitable with onions)...or go with the more expensive enviromesh(or net curtain) tunnel.

            I had a sucessful barrier of fleece supported by canes last year, but hopeless on a bigger scale as just blown apart...going to cover the bed with evironmesh too.

              I had loads of voile left over from my mobile photographer days. Have sown it all together into a big cage which will be supported on canes. It's all different colours and will look vile but if it gets us maggot free carrots it will be worth it. Get down to your local charity shop and buy some net curtains. I got 4 the other day for a couple of quid.

                My carrot bed has a side and end constructed of 18 inch high perspex, a side and end constructed of 18 inch high debri netting, and the 'roof' has a roll back single section of enviromesh!

                    Somehow I don't think the neighbours will when they see it. Hope I don't get kicked off
