This is an excellent time to spray horticultural oil on your azaleas (underneath the leaves) for lacebug. It's also a good time to take soil tests and turn them into your local extension office. It would be far better to find out a little bit about your soil (pH, especially) before adding anything to the soil. Right?

In the meantime, you can freshen up the mulch layer around your azaleas.

Thanks, I will go ahead with it. I just put fresh mulch down but have not tested the soil. Thanks again.
