petunia plug plants - can I split them?

[CityChick]

I ordered some petunia plug plants.  They're arrived, and I've noticed that a lot of the individual cells have got 2 tiny plants growing in them instead of just one :D

Can I split them to maximise the number I've got? 

Or would it be better to leave them alone incase I damage the leaves and/or roots when separating them?

Thanks for any advice.

I have done this in the past with impatiens speed plugs with no problem so I don't see why you shouldn't do it with petunias. It is really no different to pricking out seeds sown in a pot.

Thank you - that sounds positive then :D 

I haven't grown many flowers before, but I just kept getting a nagging thought that the roots of some veggies don't like being moved and fiddled with.  So I thought I'd ask just incase petunias were a bit particular like that.  Okay... i'll stop waffling and get back to gardening now ;D
