Hi, this is my first post, I'm a gardening novice - very keen but lacking in knowledge! Thought these forums would be a big help...

A couple of years ago I planted a mossy saxifrage (Peter Pan), it's now spread to a clump about 12 by 6 inches. It looked really pretty last year but this year it looks like its gone brown and bare in the middle but the edges of the clump looks healthy. Can anyone tell me what's happened and what I need to do to get it looking good again?

Hi Rachael, I have read your post,but I don't know the answer. 

I think I have had the same problem with a plant but I'm not sure it was even a Saxifrage.It was a sort of Alpine that I got very cheap,doing very well but then it went brown but the ends remained green

Maybe replant the green& healthy bits?

Hi Rachael, exactly the same has hapened to em this year, every single clump has died back inthe middle. I think it may be due to the very damp conditions this year and the lack of air in the centre of the clump has lead to rotting. I'm hoping they will recover next year.

If not then mossy Saxifragaes are dead easy to propagate. Any piece with roots will soon grow into a healthy clump. Once the centre has gone like that it rarely fills up again, the natural habit is to grow outwards from the centre.

I have just removed a clump of Peter Pan, it was over a metre wide and a bit more long. They can get very big.

Oh and they also dislike midday sun.

It may well be birds. Don't laugh, folks. They attack them, maybe for nests (not up on wildlife) . I experienced this few years back when I grew alpines. Try upturned hanging basket over the clump

I bought one of these in the spring and it's been really pretty.  I assume spring would be the best time to try propagating it, would that be right?

Thanks!

Saxifrages tend to do this - like most perennials they grow old and woody in the centre and the younger stronger growth is around the outside.  It just needs lifting and dividing every few years like most perennials do. Discard the old woody centre

My saxifrage was doing so well, then when I came back from two weeks holiday it was wilting and brown at all the roots.  I lifted the green parts up and saw the earth they were planted in was absolutely teaming with wood lice.  What can I do - use nematoids?  Help please.

Woodlice are harmless JMF - they feed on decaying material so they've not caused the problem. It's possibly just gone short of water if it's been very dry.  Vine weevil can cause sudden wilting in plants so perhaps lift it and check the roots for the creamy white grubs, although they're not usually susceptible in my experience. 

Nematodes won't be any use.....the Woodlice are simply there to feed on the decaying parts of your plant.

Take cuttings from the green pieces of your plant and start again.  Check that the soil conditions and the site are the best for your saxifrage.

A good soaking often revives them.  

I just pick out the dead bits
