I have tried this technique once or twice without much

(as they do in a compost heap if you put too many in
at once).

I would really like to use the clipping to mulch
around my respberries as they are getting old and weak
and I was hoping that would help next years canes
develop.

Any tips please?

If you dry them (rake them up rather than collect them) then they
won't heat up when you apply them as a mulch.
Thin layers regularly of fresh clippings is the way to avoid it
heating up.
