Hi,
I,m new to this but need advice about leucothue royal ruby..a stunning shrub but when do i prune it and how hard..I,ve also got red robins do i prune these at the same time?

 

Hi see here for a bit of info on your Leucothoe keiskei "Royal Ruby"( Keiskei Fetterbush )

no real need to prune but here is some pruning info relevant, if you feel you must (it is very slow growing)

Prune your Photinia fraserii "Red Robin" in early summer, but only if necessary - (they are not fantastically fast growing & Leucothoe is even slower) back to just above a pair of leaves with secateurs.
Hope this helps
