I hope so - I use it here in NZ - just don't try it on Rhodos or
camellias (they hate it). Actually my favourite is cow manure and
sawdust - makes HUGE roses, but I can't seem to get it now I have
moved to Christchurch. Still trying out alternatives.

Would a trailer load constitute payment for Bed and Breakfast sometime? :-)

The roses will do fine, I put about a cubic metre on my roses early last
spring. (there's an aweful lot in a cubic metre :-/ ) I shoveled it on about
three inches thick, I had also dressed the soil around the plants with blood
and bone and they really responded. Lady Hillingden has increased in size
remarkably and Picture, normally a fragile little bush , put out new basal
shoots and flowered beautifully.

The only thing to be aware of is that mushroom compost tends to be very
alkaline to watch out that you don't kill off anything nearby such as
camellias, rhododendrons or any of the ericaceus shrubs.

I wondered about that! Actually I used to get a load each year from a
service club who did a fertilizer drive to raise money for charity,
but they don't seem to do that here. I guess I could try to find a
farmer, but it was a lot easier getting it delivered!

And for good reason. Mushrooms prefer a slighly alkaline environment (ph
7.4 - 7.6) which Rhododendrons and Camellias detest. Roses aren't too
fond of that pH range either, but less sensitive than rhodos.
Lesson: when using M.C. on roses, it's worthwhile to adjust the pH with
a bit of peat or redwood.

Given the performance of my roses this year I would have to agree with
this. Had used MC as a mulch on the roses for a couple of years but
this year got a big load of Cowmanure+Sawdust and put it on about 3"
thick and the performance has been wonderful. Huge basal canes and
lots of em!

Don't worry about it, all you need to do is purchase some powdered sulphur from
your garden shop and broadcast it by hand over the composted area. About 1/2 a
handful to every square metre will do, rake it in lightly and water the beds.
That should address any problem of alkalinity.
