fertilizer for river birch and azalea

[Stonewall]

Anybody have any suggestions for fertilizing river birches and azaleas? A new client wants his river birches to take off and his azaleas look weak.

my best bet for you would be some plant tone. for the azaleas you can use holy tone or acitone or miracid. but for the birch tree i would say some plant tone should do you some good. that will also work well for the azaleas. maybe not as well as the others... but give it a try.
