Something is eating my Marigolds. I bought a small flat of marigolds two weeks ago and planted half of them in my vegetable garden the other half in my flower beds and flower pots. Within a couple of days the flowers in my vegetable gardens had almost disappeared, something is eating them but I don't know what. I have checked for slugs but have not found any. The marigolds in my flower pots are fine. Has anyone else experienced this before?

Cheers
