How to prune these plants
I've just moved into this old house so I'm still discovering what everything is in the garden
Having posted a similar post, I have 2 more plants I'm looking for advice on
This one is a bit of a mess, should I be pruning it carefully cutting the dead parts out or lopping the whole thing back ready for spring? I don't know what it is but it looks similar to something I planted in a previous garden of mine that had yellow flowers:
And these (below) look to me like they might be roses..
Can anyone ID this evergreen hedge? (below)... if I trim it back is it like evergreen trees that don't grow new leaves once you cut them off?
Apologies for the bad photography, my good camera is still packed after the move so I took these on the phone camera .
