I've had some success with kebab skewers from underneath.  Make sure the soil is moist, it helps unglue them

Cumberland pie with pots and creamed leeks with a side spoonful of Stokes red onion marmalade. That's me sorted.

Sounds like a modern hybrid that can also be grown as a climber like my Gertrude Jeykll. You may lose some flowers but it shouldn't kill it.

I once grew them but they weren't that prolific. May I recommend Elegance as a big fruiter with a great taste. There's also Marie du Bois which is also a good one. I have both here. 

I have rose bush that really needs taming.  Normally I would just dead head after first flowering (flowering now) and get a second bloom  end of summer.  I'd really like to prune it back hard to about 3ft tall as it's currently got quite a few stems waving around about 9ft up!  Will I kill it if I cut back hard after flowering in summer.  I'd like to get it down to below first leaves.  Not sure what type it is, vigorous, a modern hybrid I think.

Thanks.
