I can't promise four feet, as the stems do come up very quickly;
but
I found when I had a lot of them that they wouldn't -- I'm
guessing
here -- get above about five by the end of the summer. Cut them
off
six inches from the ground every year, about the end of this
month,
and you'll be all right. Stay ruthless in subsequent years, too.
The
same treatment for golden osiers, but a couple of weeks earlier,
as
they shoot sooner.


so I cut down to say 6" this month, how quick will they grow again ?

They'll reach four or five feet this season.
