Hi Helen,

Spring is better as dividing them weakens the roots. Do it now and the wind and snow may weaken them too much.

thanks Kildermorie

Hi Helen, is there a reason you want to split them? We tend to let ours clump up.

Personally, I divide them every spring as I think they look better (certainly grow larger) as single plants. You also gain more plants for the border. They also seem to flower more strongly as have less competition.

I think Foxgloves look great in a clumps but Primrose and Primula (Primulae?) as singles, but that is personal taste.

your probably right MG , I just thought it would be best for them?

It is indeed personal taste Kildermorie - I think individual single rosette primulas look like bedding plants 'but' that is just my point of view. I do split them when they get to be too big of a clump.
