Hello. I have a smoke bush which is 4 years old.I has never flowered.
Every spring I prune it to near groud level as this is what the label
said. I have been told that you shouldnt prune every year. Is right if
so how and when sould I prune. The longest stems are about 6ft( 6 or 7
like this) and the rest about 3ft.
TIA
Gaz.
