Azalea, Acer, Magnolia and Camelia

Hi
I am new to all of this but I do love to see a well maintained garden, I have a large garden back and front with a lot of Azalea, Acer, Magnolia and Camellias etc to which I have been advised to smother both gardens wit Irish Moss Peat but was wondering if I should mix the peat with horse manure 50/50 mix, can anybody please advise me on the best thing to do?
Manny Thanks

ITS simple Ericaceous Compost is the key............Good luck and god bless
