I have for several years, when cutting off the tops of leeks prior to cooking, spread the leek leaves along the carrot rows - the smell seems to deter the arrival of carrot fly, and the leeks gradually rot down over the months and ultimately get dug in. Carrots protected this way have been virtually untouched by the fly (which is very bad on our allotment site)
I like that idea Pentillie and will give it a try. I've had resonable results growing alternate rows of carrots and onions in the past with the view that the smell of onions masks the carrots smell. I will be harvesting the last of my leeks over the next few weeks and the carrot seeds are just germinating, so the timing is rather good.
I've been growing carrots in 60cm high raised beds for the past 2-3 years with no fly damage at all but they got vine weevil last year so I'm trying them back in the ground.
A trowel in the hand is worth a thousand lost under a bush.

I have grown mine in pallet collar boxes and pleased to say no problems , fleece over them until they are a reasonable size
