Dave,

Have you looked at these sites? Maybe you'll find your answers in one
of them.

I believe the "gardens" you were referring to is the Royal National
Rose Society. Seems their website is down, or has moved. It used to
be rnrs.org

I'm curious about the details of that pruning method that some Brits
use for bushes. You know, the one where you just make a straight cut
across the middle top of the bush. Does anyone have any details about
it? Where do you choose your line? Do you do any other "lateral"
pruning. Etc. Etc.

My big Aloha is getting rangy and "tall growing" instead of its normal
bush form. I'd like to get it back to normal if possible. It's now
about 10 feet tall in the middle but looks sparse on the side. It used
to be really round. If this odd pruning method can help, I'm game. My
previous pruning methods haven't really helped the shape of the bush.
