Is it possible to transplant carrot seedlings?
You can, but the leaves will probably turn purple/red then die. Best to sow thinly or in paper tubes, not toilet rolls though because they don't break down and can turn fungal or slimy - put me right off when it came time to eat them.
If direct sowing, I find that by putting a clear flattened out bag over the top aids germination - keeps the moisture better. Same with parsnips.
Thanks for your replies. Sowing again seems to be the best solution.
Carrots are similar to parsnips and have a tapered root. If the root is broken when transplanting, the carrots, if they survive will fork leading to misshaped carrots which is the reason most will advise to sow direct where you want your carrots to grow.
I'm happy to be wrong but sowing carrots in stony ground leads to the same problem.
I prefer to grow carrots in pots, sowing then direct and harvesting as mini veg. If you sow in pots though you need to be ruthless when thinning out. The root needs room to grow, and it won't row to a size were it's worth harvesting if competing with other seedlings.
