Rhodies and azaleas have shallow fibrous roots that can be quite
densely packed. I wouldn't dig closely around their roots. Give it a
thick mulch of leaf mould, pine needles or peat. I wouldn't use
commercial ericaceous compost as it can be rather dense, and burying
the roots might deprive them of air. For feed, I'd water with a
solution either of commercial ericaceous feed, or simply sulphate of
ammonia, one level dessert spoon per gallon.

I'll get hold of one of these liquids.

When should one feed/how often?
