The message
from "d.boddey" contains these words:

I have a winter flowering shrub called mahona (charity) can anyone tell me
when they should be prunned ,and can they be cut back hard.
It is about 6ft tall now

They can be cut back hard, but you would lose this winter's flowers,
so I'd wait until late spring to do it. Mine is flowering now, nice
scent too.

Janet.
