I planted some Amsterdam carrots in a deep container in the greenhouse a few months ago. The packet says harvest from May onwards. It is now well into June and I have plenty of healthy, green tops but nothing formed at the root     

Can anyone shed any light on this ?

It's happened to me before and with Amsterdam forcing. They looked fabulous but zilch underneath all that lovely foliage.  I have no idea what caused it. Mine were outside

That doesn't make sense. Carrots are genetically programmed to grow roots. The only year I manage to keep the slugs off them and this happens. I am just not meant to grow carrots. There are unknown forces at work

Two things come to mind: The soil is perhaps too rich (especially in nitrogen) and maybe too much watering?
I grow all my carrots in pots, and I reuse the soil that has grown the early potatoes. I do add a handful of poultry manure, and only water them when they show wilting.
I have grown 'early nantes' There is a lot of folliage but some of the roots are as thick as my finger and ready for thinning out.

They are in normal compost and I keep them watered as normal as anything. I don't want to risk them wilting as they may never recover. Besides, surely the root needs plenty of water to develop.

Mine aren't doing anything yet.  It has been rather cold.

I suppose it won't do any harm to just leave them. Just dissapointed as the packet says you get a very early crop.

I also only tend to water when the first signs of wilting appears, from memory if you limit watering then it encourages the root to delve deeper looking for moisture.

Ok, thanks for the tip

I have not watered as suggested but they are still very tiny and hardly worth pulling. Not very long despite the deep compost

..... and maybe too much watering?

Hmm need to stop the rain then.

They are in the greenhouse.
