My advice is, DON'T.

Just wait and watch, it will expand at an alarming rate once it is ready
and, unless you are able to contain it, you will wish you had never let
it.

They are absolutely taking over my garden and I am quite powerless to stop
them. They are growing at an alarming rate all amongst thick shrubs, on
steep banks, where I can't possibly get at them. Once they start they will
put out long leaders which root and start the process all over again so
that, in a year, one bush can became twenty, ad infinitum!

I can't poison them without killing everything around them; I can't dig
them
out because I cannot get into them without cutting other plants down. If
anyone has advice on how ho kill them in this situation, would they kindly
let me know.
Use a brushcutter or tether a couple of goats near it. Mine use to scoff
brambles like they were manna from goat heaven.
