The Q&A Archives: Annuals Dying

Question: I have a pot with Petunias and Marigolds. They are slowly dying, and have a soapy, iridescent residue. What is it? Pest?

Answer: The silvery residue is probably from slugs or snails. These pests feed at night so you rarely see them, but their damage is quite apparent. I use the iron based product called Sluggo. It works beautifully. Give it a try.
