fresh herbs

[fairydust]

I brought some fresh corriander from tesco and wondered can i plant it in the garden and take snipping when required

If it's one of the growing herbs in a pot then yes, you can.

yes I always do

I bought three pots of basil a month ago and planted them in a tub in the garden and they are still going strong (and we seem to get through mounds of the stuff)

yes it is - will it spread?
would be better to put it in a trough?
