carrots in a raised bed?

hi, i have been told that carrots don't do well on our allotment site as its clay soil.
if i made a raised bed deep enough to take them and fill as the carrots like would i have success?

No fresh manure or the carrots will fork.

That's exactly what I did as I had very heavy clay.  I used a 50/50 mix of compost and sharp sand and had very good results.  Never could grow carrots in the clay soil.

I have London clay soil and have raised beds, I got some great carrots last year by digging drills and filling with compost which I sowed the seeds in. I then covered the seeds with more compost and watered. I would have had even better results if I hadn't sowed too many seeds and then not thinned properly. This year my problem has been the heat (tops drooping over) but have thinned and I am digging up some decent carrots now. I was also told I wouldn't be able to grow carrots or parsnips, but it's not true.  

thanks all i will now go on to prove them wrong (once ive cleared the site that is)

Raised beds are deffinately better for carrots

I also have a very clay soil. I dug in several wheel barrows of spent compost last autumn. This bed then became a perfect place for both garlic and carrots which do not like clay soil. Sand would have a similar effect, ie aid drainage without adding too much nutrient that would cause carrots to fork.

The spent compost was from the council and has really lightened up the soil.  Alternating bewteen different additions (eg manure, spent compost, home made compost, green manures etc) mean that you can grow anything if you organise your rotation effectively.

Having said that, carrots grown in pots in a 50:50 sand:potting compost mix work brilliantly and can be started off really early and carry on late into the season.
