Answer: You can prune azaleas to keep them neat and compact. Since these shrubs spend the summer months developing flower buds for the following spring's floral display, you'll want to prune them back immediately after they have finished flowering so they have the rest of the summer to develop new growth.
I'd plant Variegated Fallopia, Hosta, lamium or coral bells beneath the azaleas. They all prefer moist, acidic soils and shady sites.
