can anyone tell me what variety of carrots and onions that can be grown in pots i do not have enough room in the garden to grow them .
They can both be grown in pots, variety isn't really important, just sufficient depth to the pot with carrots.
I would use any Early variety of carrot described as 'stump rooted' - they don't need too much depth. Chantenay is a good one for pots.
