When to divide Saxifrage?

Does anyone know when to divide or transplant saxifrage? I have looked and looked and found no information. I hate to guess and possibly lose them.

 

What kind of Saxifrage?
Silvers and Porophyllum types are best done from cuttings, about now.

 

I believe they are paniculata's? The tag just said Saxifrage but I looked at pictures and found one that looked like mine and it was labeled paniculata. How do you divide them or are cuttings better?

 

S.paniculata is one of the silvers. Cuttings are dead easy. Take a rosette or two or three from the edge of the plant, with a bit of stem and put them in a pot of sandy compost. they will root is a very short time, especially if you can manage to get rosettes with a bit of root on already.
I would not really try to divide a plant unless it was very large and even then it is more than likely that it would fall to pieces and you would end up with lots of bits to use as cuttings.

 

Thank you for helping me. As soon as the blossoms die I'll do as you said and take cuttings. It's one of my favorite plants as it is so pretty when it blooms but then, when they fade, the foliage is just as pretty. I can find room for lots of them.

 

Don't forget that the rosette which flowers will die. I like them too and have grown well over 50 different forms of the various species. They come in a range of colours too as long as it is based on white. So pure white, white with red spots, white with pink spots, white with so many spots the flowers appear, red or pink. There is also a pale yellow one.
If I get the time tomorrow I will take some photos of taking cuttings to help.

 

That would be really appreciated as it something I haven't really tried before. Thanks!

 

So here goes.

I used Saxifraga koelnatiana atropurpurea as I need some of it for myself.

Three pieces, one with out roots, but all of them will take.

Potting compost and Sharp sand, equal amounts.

Mixed evenly.

Most important label with name and date.

Holes for the cuttings.

Insert cuttings, water in and put in a shady spot.

 

Have to admit that this is how I normally take cuttings.

Pure sharp sand and in a frame with a shaded lid. Used to have heating cables under the sand, but they stopped working a long time ago. Stuff still roots though.

 

And a few Saxifrages. I have not got a picture of the yellow flowered one.
