Q.Verbena Problem
Hi, I was wondering if you could venture a guess as to what type of white growth is inside my Verbena planter, and what do I need to do about it? Photo’s are attached Thanks !

The pictures are too far away. Not sure if things are moving in there, if things fly away when you disturb the area or nothing is changes when disturbed. If nothing changes, it could be a bad case of powdery mildew. Some triangular shapes in the second picture made think of a whitefly infestation. There are, however, other possibilities. Amongst verbena pests, there are white aphids and mealybugs. Your best bet is to take a sample for identification to a local garden center using a sealed, transparent plastic bag.
