Another raspberry question.
I have just heard that raspberries need a neutral to acid soil. Mine
is on limestone. Any advice on what to mulch with to make it more
acidic? Would rather not use peat. In the past I've mulched with
mushroom compost. Oops!

Compost which has had clean (i.e. untreated) sawdust in it is good. Some
iron filings might help too, if you can get them. (If not, old nails,
etc help.)
