Will Cecile Brünner kill La Doyenne du Comice?

As you will see Cecile Brünner is really thriving in my garden and she's started to invade the big pear tree. I like the effect but I'm wondering if I should nip it in the bud -- will she completely smother the tree?

 

Looks great but anything that grown in a tree will rob light and create more weight on the branches and stops the air cirulating easily any chan chance you can prune the rose a 1/4 out each year I would also feed the pear tree xtra food in the spring , blood fish and bone would be ideal just to help it cope more ...

I don't dare use blood fish and bone because every fox in the neighbourhood will come and have a party every night in my garden.

Whatever Cecile intends to do it looks absolutely stunning.

 

When to prune?

(I’m very tempted to just take it all out of the tree, even though it would look amazing in two or three years if I left it. The idea of pruning a rose at the top of that pear tree every year gives me the heeby jeebies - I’d have to call someone in with a triple ladder.)

 

It's interesting how everyone seems totally relaxed about growing roses through trees on the internet -- I can't find any advice about pruning it, or it being a danger to the tree. Graham Stewart Thomas is equally cool, saying "Those ramblers which are given trees and hedgerows as supports are best left to themselves . . . "

Anyway Cecile is turning into such a glorious plant that I'll give her a long leash, as they say. But if anyone has had any experience of this, please say!
