Having recently purchased a mulcher, I'm wondering if there is a
consensus to whether certain waste, like rose prunings, shouldn't be
used as mulch around other plants as they might carry disease.
For example, I wouldn't put maple clippings as mulch, they might
transmit bacterial cankers or even verticillium. I'd probably not put
rose, and although I did use a lot of willow the other day after putting
it through the machine, now I wonder if that was wise. Things like
elder or hedge laurel, give me no qualms.
So, what garden waste would be unsafe to use ground up as mulch around
trees and shrubs?
Thanks,

P.S. saw the first snowdrops poking up this afternoon!

Living in a phytophthora-affected area I wouldn't use shreddings from
any host species.

That sounds reasonable.
The other day I shredded a lot of bramble and didn't mulch with it on
the theory it might grow from tips.
I suppose my line will be drawn at anything that might carry a pathogen
or will regrow.

I use everything, except plants that die under suspicious circumstances!
I don't put rose shreddings under the roses and I have never known
anything grow from shreddings so I don't worry about that.
Unlike Mike I am too lazy to compost I just put it all straight on the
ground

I find that what ever I put down as mulch the blackbirds move it
around so much that it is kept aireated and all theie scratching about
moves weeds as well.
