Hi Lee,
These shrubs are a magnet for fungal problems and pests, especially where we live.* Of course they looked lovely in the nursery.* They probably kept them happy with lots of chemicals. Since you mention the sticky clear resin called honeydew (waste material of some pests), I suspect yours have aphids, scales or comstock mealybug.

You can click here to see different kinds of scale insects as I can't seem to find a picture of photonia scale.

Neem oil applied every 5 days until they are gone should do it.* You can also use insecticidal soap applied the same way.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
