My marigolds look as if they are being eaten. Upon closer inspection, I noticed what looks like teeny slugs! Can you help me? In all the years that I have planted marigolds I have never seen such a thing. Any suggestions would be appreciated. Thank you.

You can also try spraying the plants with neem oil to prevent other insect pests from munching on them. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
