Am I doing something wrong?

Did you also add something like Blood Fish and Bone or Growmore to the soil?

Manure/compost etc give you lovely soil but don't always supply all the required nutrients.
Yours have also been grown in a different environment to hers which can explain the difference....possibly more exposed?

Another consideration is that the compost in pots will heat up quicker than raised beds. 

Annother factor to consider - is - being greenfingered!! My neighbour over the field seems to do far better than me without all the LTC that I give my plants. I HATE her!!!!! (  :wacko:I don't really - she's a love!) :happy:

I think Trillium might have a point here. I am growing carrots on the allotment and in pots at home. The potted plants are all doing very well with very good germination. Not so on the allotment with reseeding again being the norm.
Because the potatoes are running late I have no room yet for the brasicas. They are also growing in pots and finally in supermarket buckets and they are all thriving.
The common factor is that I fuss over them and water them most evenings, and yes they do have an occasional feed.  The allotment is 5 miles away.
Raised beds by their nature are going to dry out quicker than pots.  Also pots can be moved about and given better shelter.
Possibly they need some TLC.
