I split them and have replanted them in the front garden. I will be repotting some of the primroses I sowed in May (see below how they look now) into the now vacant pots.
One thing I learned while splitting the primroses is that it's better to split them by hand - I originally tried splitting them with a spade, but on a couple of occasions I only succeeded in separating the top of the plant from its roots.

In the pic above the pots nearest the camera contain foxgloves.
