My annual coriander question

Its running to seed already ! 

In previous years I've just taken the scissors across the top of the pot, refilled and started again when its started to bolt. This year its no more than 3 inches high so Id end up with very little.

Can I give it a bit of a trim without killing the lot, is there a knack ? every time I've tried the plants haven't recovered.

I think its just been too hot in the greenhouse for it this year.

Towards the end of last year, although it was cut and dispose of I was getting huge amounts from the smaller morrisons flower buckets which I was freezing. Not a nice as freshly picked but better than the bought stuff.

Are you growing a seed-cropping variety, or a leaf-cropping variety as this could influence things?

Lardman - if they're going to seed then I guess that the foliage has already changed shape and therefor the flavour has suffered already. I'd chop them off at ground level and see what happens. Alternatlively let them go to seed and save it for next year's sowings. Like you said, you've already planted some more so it's not the end of the world if nothing happens.
