When to transplant

[Small pumpkin]

The herb bed that was already here when we moved in has got to be changed. It is a small patch of ground with a little less grass in it than the lawn and the only herbs are 2 massive oregano plants and one large chive plant. When is the best time to split and put into pots? so I can turn the rubbish herb bed into a raised bed herb paradise

any time now, when you can keep the transplants coolish and dampish until they become established again.
I'm always ripping out the oregano in my own garden, it's a bit of a thug and self-seeds freely. Chives though, I can't get enough of, I love it

Thanks Two_Sheds
I had my finger crossed, that would be the answer. I'm going to start that little project now.
