So a friend has moved into an old house his grea grand parents first had, needs tidied but it has a great big rose out the front thats been there aslong as his own grand parents remember. But its in a sprry state and he says is going be moved, but ajy ideas on it
?

hopefully you can see the only decent bud, the leaves that are large dull looking and broad, and the rootball that is literally hanging half off and has been for a long time supposedly! how its living and growing is beyond me

so any ideas folks?
